Friendly bitcoin API binding for Python.

bitcoin-python is a set of Python libraries that allows easy access to the Bitcoin peer-to-peer cryptocurrency client API.

This software is Open Source.

==Documentation==
Documentation can be found here, or in the source archive. It is built using Sphinx:

http://laanwj.github.com/bitcoin-python/doc/

==PIP==

The library can also be found in the Python package repository

https://pypi.python.org/pypi/bitcoin-python/0.3

This means that it can be installed using '''pip install bitcoin-python'''.

== Project status ==

According to [https://pypi.python.org/pypi/bitcoin-python/0.3 the PyPI page], bitcoin-python is not actively maintained. The page suggests using [https://github.com/petertodd/python-bitcoinlib python-bitcoinlib] instead, which offers far more features.

The PyPI page for bitcoin-python leaves open the opportunity for anyone to take up the maintainer role for bitcoin-python, if they contact the developer.

How to accept Bitcoin, for small businesses

2014-11-08T20:43:54Z

Andy2993:

{{merge|Merchant Howto}}

This guide is intended for small business owners who wish to help promote Bitcoin by accepting it as payment for goods and services. It's written with the assumption that you operate a regular business that sells goods or services for regular national currency such as dollars, and that you wish to accept Bitcoin as another legal way to pay, and that you intend to pay taxes on your Bitcoin income just like any other income.

With Bitcoin being touted as a way to conduct anonymous transactions and as way to compete with government currency, many small business owners wonder what's the right way to accept and account Bitcoin, or if it's legal or ethical, or whether and how they should pay taxes on income received through Bitcoin.

As far as we know, Bitcoin isn't yet formally recognized by governments and authorities as a "currency". But in practice, Bitcoin is likely no different than accepting payment in other forms, such as cash, or gold, or scrip, or gift cards or foreign currency. We think that it is pretty much the same as the local businesses of Great Barrington, Massachusetts choosing to accept their locally-printed [http://www.reuters.com/article/2007/06/19/us-usa-economy-berkshares-idUSN0530157720070619 "Berkshire Bucks"] to support their local economy.

====Starting to accept Bitcoin for transactions====
Accepting Bitcoin at a small business is best started in whichever manner keeps the accounting simple for you. This will vary by the type of business you are operating.

===Start with a sign===
[[{{ns:file}}:WeAcceptBitcoin.png‎]]

If you expect that the number of people interested in using Bitcoin is small, you might simply start by posting a sign or a note: "We Accept Bitcoin", and ask people to contact you directly in order to make a payment. Even if hardly anybody uses Bitcoin as a payment method, you're helping Bitcoin in two ways: one, by increasing awareness, and two, by making your customers more willing to accept Bitcoin as payment from others in the future, because now they know somewhere they can spend it.

===Utilize a merchant solution===
If you sell things on your website (goods or services), you'll want to use a [[#Merchant Services|Bitcoin merchant solution]] to accept the Bitcoins (you can usually opt to have them converted to USD or other currencies automatically with some services).

If you sell things in a brick and mortar shop, customers can pay using hardware terminals, touch screen apps or simple wallet addresses through QR Codes.

===Smart Phone or Tablet===
You can use a wallet address with any wallet. For that it's best if you can place a QR code near your cash register to which the customers can scan with their phone and pay (use http://ma.eatgold.com/accept to make a QR code sign). For a more convenient solution you can use a dedicated app or webapp that generates a QR code on the fly including the amount.

===Point-of-Sale hardware terminal===
With custom hardware you can integrate with existing registers and point-of-sales solutions (examples: [[File:Coinkite.gif|20px|link=https://coinkite.com/promo/wikibiz]] [https://coinkite.com/promo/wikibiz Coinkite], [https://xbterminal.com/ XBTerminal], [http://www.bitstraat.nl BitStraat]).

===Accounting===
When a customer makes a payment, you might simply issue a credit to their account. Ideally, you want to enter it in a way that suggests you received a payment. You could consider entering it as a "discount", but you may want to consider whether this inappropriately disguises the nature of the transaction. If on the other hand, you're giving "discounts" for Bitcoins, but then you are selling the Bitcoins for currency and then counting that as income, then chances are good that your calculation of income is making up for it. Ask your accountant.

===Businesses that offer gift cards===
If your business sells gift cards or gift certificates, you may find that the easiest way to accept Bitcoin is to accept it only for the purchase of gift cards, and then require the gift cards to be used for actual purchases of goods or services. This way, the accounting practices you already have in place for processing gift cards can be put to use. The accounting for Bitcoins would then be minimized to tracking sales of a single SKU.

This method is also ideal for retail food establishments and convenience stores, where the payment of Bitcoins through a mobile phone for a small daily food purchase might be cumbersome or disruptive, especially in front of a line of other customers. Bitcoins in this case would be best used to reload prepaid cards that can then be swiped at point-of-sale.

If you don't accept gift cards, but you already accept credit cards through a swipe terminal, consider the possibility that you could add a retail gift card system through the swipe terminal you already own. Many point-of-sale terminals, including ones from VeriFone®, are designed around the ability to support multiple applications on the same terminal. Gift cards are also highly profitable because of "breakage", or in other words, the fact that a significant percentage of them never get redeemed.

You could consider adding a private label gift card program from a provider who specializes in this, not just as a jumpstart to accepting Bitcoins, but as an extra boost to income. A private label gift card service provider necessarily have to handle your funds - they can simply provide a solution that keeps track of the balance on the cards on your behalf, including features that allow users to check their balances by phone or by web. Such a solution, of course, is also what makes the cards swipeable through the card reader.

===Businesses that mail invoices===
Does your business send out invoices to customers? Adding one line may make a huge impact for the Bitcoin economy. Perhaps you list it as a payment option just after Visa, MasterCard, and American Express, even if that means your customer must call or e-mail to make a payment.

If you have access to the programming expertise such that you can generate Bitcoin addresses programmatically, consider generating a brand new Bitcoin address for each invoice, and print it on the invoice. When a Bitcoin payment arrives, you'll automatically know where it should arrive.

Customers might wonder how much BTC they should pay in order to satisfy an invoice in full. Your invoice might suggest an amount. For example, if your invoice is for $100 and BTC's are currently worth $1.24 each, your invoice might suggest that it can be paid in full ''"with a payment of 80.65 BTC if paid by (date)"''.

You might be able to anticipate the possibility that even though a Bitcoin address can be printed on an invoice or payment stub, that they are very cumbersome for most people to type, especially being a mix of uppercase and lowercase letters. However, you should probably still do it anyway. The customer is probably going to want some paper trail for his payment. Giving him a pre-printed payment stub with a pre-printed address will satisfy that, because the customer can independently and publicly prove through [[Block Explorer]] that the payment took place.

Does your business have a website? On your invoice, consider allowing them to go to a special URL to get the address to make a Bitcoin payment just by typing in their invoice number. For example, ''ht<nowiki>tps://ww</nowiki>w.yoursite.com/paybtc'' with a form they can enter their invoice number, or just ''ht<nowiki>tps://ww</nowiki>w.yoursite.com/paybtc/60365'' for paying invoice #60365. This way, they can see the Bitcoin address, copy and paste it directly into their Bitcoin client.

Use a brand new address for each invoice whenever possible, and use it only once. This benefits the customer as it removes any ambiguity as to which customer is making which payment and for which invoice.

Online wallet supporting invoicing, subscriptions and recurrent payments, [https://www.xcoinmoney.com/info/sending-paying-invoices xCoinMoney]

===Avoiding fraud===

You should also consider the possible risk that fraudsters could send counterfeit invoices to your customers, and entice them to make a payment to a Bitcoin address they control, instead of you. While that isn't likely in general - it depends on how well a fraudster could find out who your customers are in the first place - it would certainly be an unpleasant situation if it ever happened. One way you could control that is, whenever possible, never let people try to type Bitcoin addresses off payment stubs - instead, force people to get the full Bitcoin address from your website via secure SSL. But, still print ''most'' of the address on the payment stub (perhaps with four or five characters starred out), so that the customer's need for a paper trail can be satisfied, so they can prove they paid if there is ever a dispute. Merchants can also use the IP address geolocation to understand the close proximity of users. There is automated solution such as [https://www.fraudlabspro.com FraudLabs Pro] that automates the screening of Bitcoin transactions to determine risk level.

==Setting Prices==

When a business accepts bitcoins for payment, there generally is the need to convert them to the currencies used for paying suppliers, employees and shareholders. Some merchants set prices based on the current market rate at the time the price quote is presented to the customer (merchant services like [[File:Polycoin_favicon.png|20px|link=http://www.polycoin.io]] [http://www.polycoin.io Polycoin], [[File:BIPS.gif|20px|link=https://bips.me]] [https://bips.me BIPS], [[File:Favicon-32x32_.png|20px|link=https://bitcoinpay.com]] [https://bitcoinpay.com BitcoinPay], [http://www.bit-pay.com Bit-pay], [https://coinbase.com Coinbase] or [http://paysius.com Paysius] do this automatically).

[[Bitcoin Prices]] lists the exchange rate for many currencies on multiple exchanges.

When prices are determined using an automated process, the current market rate can be based on either a current price or on a weighted average basis. [[Bitcoin Charts]] provides a [http://bitcoincharts.com/about/markets-api data feed that provides weighted prices]. [[Bitcoin Average]] also offers a weighted average price index, featuring average price across all exchanges reachable in the world and in over 150 currencies. 24h sliding average price index is also available and all data is [https://bitcoinaverage.com/api.htm reachable through the API].

When bitcoin funds for purchases are received, some merchants instantly exchange those proceeds into the preferred currency used (again done automatically by [[File:Polycoin_favicon.png|20px|link=http://www.polycoin.io]] [http://www.polycoin.io Polycoin], [[File:BIPS.gif|20px|link=https://bips.me]] [https://bips.me BIPS], [http://www.bit-pay.com Bit-pay], [https://coinbase.com Coinbase] or [[File:Favicon-32x32_.png|20px|link=https://bitcoinpay.com]] [https://bitcoinpay.com BitcoinPay]. Hedging for each transaction can nearly entirely eliminate exchange rate risk that the business is exposed to when accepting bitcoins for payment.

==Contract==

A sales contract might be used to ensure that specific terms are met to lessen the chances of a misunderstanding. For instance, the party sending payment is responsible for paying any [[transaction fee]] that might be necessary. A contract might specify that a transaction fee must be paid and what amount, so as to prevent the situation where the transaction is considered a low priority transaction and thus isn't confirmed quickly.

Other items that might be addressed in a contract:

* Requirement and handling of escrow through an [[:Category:Escrow_services|escrow service]].
* Jurisdiction for disputes.
* Refund policy (particularly with the exchange rate being volatile)

==Paying taxes on Bitcoin income==
[[Tax compliance]] is a topic of concern for small businesses. We aren't accountants or lawyers, and can't give legal or accounting advice.

But in many respects, Bitcoin transactions work very much like cash. Just like Bitcoin, cash is anonymous and doesn't leave a paper trail, yet is widely used in commerce every day.

Ask yourself how you would handle a cash transaction. Do you accept cash transactions? Do you normally pay taxes on cash transactions? The answer for Bitcoin should probably be the same.

As for how to decide what a Bitcoin transaction is worth... the IRS, as far as we know, has never issued a guide mentioning how to value Bitcoin transactions. But they probably have rules and guidelines on how to value transactions made in foreign currency or "cash equivalents". We imagine the accounting would be similar.

With Bitcoins, there's likely to be some difference between the value of BTC when you received them as payment, versus when you go to exchange them for another currency like USD, should you decide to do so. This scenario, likewise, would be no different if you accepted foreign currency or gold as payment. Under some scenarios, it might make sense to book the dollar value of BTC income as it is received, and then to book any difference incurred when it is exchanged for fiat currency. Under others, it might make sense to book the whole thing at the time of exchange.

Perhaps you might talk to your accountant. You don't need to get into a discussion with your accountant about block chains and private keys or the philosophy behind a decentralized currency. By comparing the fundamentals of Bitcoins to accounting concepts already well understood by the public, you can probably get all the answers you need. What would you ask your accountant if you decided that you wanted to accept ''Berkshire Bucks'' or 1-ounce gold coins as payment?

Earning bitcoins

2014-11-06T18:32:22Z

Andy2993:

These websites have bonus programs that allow you to earn bitcoins by doing things like taking surveys, answering questions, trying apps, viewing advertisements, referring others to the website, and making purchases at other websites. Some of these have many of the same offers (but they give different payouts for participating in those offers).

== Offer Programs ==

* [http://www.freedigitalmoney.com/Bitcoins Free Digital Money] Earn bitcoins by participating in sponsored offers. There are approximately 1000 offers available. Some offers are free and some require a purchase. Bitcoins are sent to you immediately after you participate in each offer. No account is needed to participate in offers.

* [http://www.iwantfreebitcoins.com iWantFreeBitCoins] Earn bitcoins by participating in sponsored offers. There are approximately 700 offers available. Some offers are free and some require a purchase. You receive a currency called BitPoints added to your balance immediately after you participate in each offer. Your BitPoints can be converted to bitcoins when you request a payout, which will be processed the following Wednesday or Sunday. The referral program pays 25% of everything earned by each user you refer. An account is needed to participate in offers.

* [http://www.rugatu.com/ Rugatu Q&A] Get bitcoins by answering questions that other members have posted. A great way to do some freelancing job if you have an area of expertise and help support the bitcoin community. Sometimes higher value bounties are posted for programmers or media artists. You can login with your existing google, facebook, yahoo or openid account.

Andy2993:

Bitcoin API call list (as of version 0.8.0)

== Common operations ==

=== Listing my bitcoin addresses ===

Listing the bitcoin [[address|addresses]] in your wallet is easily done via ''listreceivedbyaddress''. It normally lists only addresses which already have received transactions, however you can list all the addresses by setting the first argument to 0, and the second one to true.

[[accounts explained|Accounts]] are used to organize addresses.

API reference (JSON-RPC)

2014-10-30T15:24:20Z

Andy2993:

== Controlling Bitcoin ==

Run ''bitcoind'' or ''bitcoin-qt -server''. You can control it via the command-line bitcoin-cli utility or by [http://json-rpc.org/wiki/specification HTTP JSON-RPC] commands.

You must create a bitcoin.conf configuration file setting an rpcuser and rpcpassword; see [[Running Bitcoin]] for details.

Now run:
$ ./bitcoind -daemon
bitcoin server starting
$ ./bitcoin-cli -rpcwait help
# shows the help text

A [[Original Bitcoin client/API Calls list|list of RPC calls]] will be shown.

$ ./bitcoin-cli getbalance
2000.00000

If you are learning the API, it is a very good idea to use the test network (run bitcoind -testnet and bitcoin-cli -testnet).

== JSON-RPC ==

Running Bitcoin with the -server argument (or running bitcoind) tells it to function as a [http://json-rpc.org/wiki/specification HTTP JSON-RPC] server, but
[http://en.wikipedia.org/wiki/Basic_access_authentication Basic access authentication] must be used when communicating with it, and, for security, by default, the server only accepts connections from other processes on the same machine. If your HTTP or JSON library requires you to specify which 'realm' is authenticated, use 'jsonrpc'.

Bitcoin supports SSL (https) JSON-RPC connections beginning with version 0.3.14. See the [[Enabling SSL on original client daemon|rpcssl wiki page]] for setup instructions and a list of all bitcoin.conf configuration options.

Allowing arbitrary machines to access the JSON-RPC port (using the rpcallowip [[Running_Bitcoin|configuration option]]) is dangerous and '''strongly discouraged'''-- access should be strictly limited to trusted machines.

To access the server you should find a [http://json-rpc.org/wiki/implementations suitable library] for your language.

== Proper money handling ==

See the [[Proper Money Handling (JSON-RPC)|proper money handling page]] for notes on avoiding rounding errors when handling bitcoin values.

== Python ==

[http://json-rpc.org/wiki/python-json-rpc python-jsonrpc] is the official JSON-RPC implementation for Python.
It automatically generates Python methods for RPC calls.
However, due to its design for supporting old versions of Python, it is also rather inefficient.
[[User:jgarzik|jgarzik]] has forked it as [https://github.com/jgarzik/python-bitcoinrpc Python-BitcoinRPC] and optimized it for current versions.
Generally, this version is recommended.

While BitcoinRPC lacks a few obscure features from jsonrpc, software using only the ServiceProxy class can be written the same to work with either version the user might choose to install:

<source lang="python">
from jsonrpc import ServiceProxy

access = ServiceProxy("http://user:password@127.0.0.1:8332")
access.getinfo()
access.listreceivedbyaddress(6)
#access.sendtoaddress("11yEmxiMso2RsFVfBcCa616npBvGgxiBX", 10)
</source>

The latest version of python-bitcoinrpc has a new syntax.
<source lang="python">
from bitcoinrpc.authproxy import AuthServiceProxy
</source>

== Ruby ==

<source lang="ruby">
require 'net/http'
require 'uri'
require 'json'

class BitcoinRPC
def initialize(service_url)
@uri = URI.parse(service_url)
end

def method_missing(name, *args)
post_body = { 'method' => name, 'params' => args, 'id' => 'jsonrpc' }.to_json
resp = JSON.parse( http_post_request(post_body) )
raise JSONRPCError, resp['error'] if resp['error']
resp['result']
end

def http_post_request(post_body)
http = Net::HTTP.new(@uri.host, @uri.port)
request = Net::HTTP::Post.new(@uri.request_uri)
request.basic_auth @uri.user, @uri.password
request.content_type = 'application/json'
request.body = post_body
http.request(request).body
end

class JSONRPCError < RuntimeError; end
end

if $0 == __FILE__
h = BitcoinRPC.new('http://user:password@127.0.0.1:8332')
p h.getbalance
p h.getinfo
p h.getnewaddress
p h.dumpprivkey( h.getnewaddress )
# also see: https://en.bitcoin.it/wiki/Original_Bitcoin_client/API_Calls_list
end
</source>

== PHP ==

The [http://jsonrpcphp.org/ JSON-RPC PHP] library also makes it very easy to connect to Bitcoin. For example:

<source lang="php">
require_once 'jsonRPCClient.php';

$bitcoin = new jsonRPCClient('http://user:password@127.0.0.1:8332/');

echo "<pre>\n";
print_r($bitcoin->getinfo()); echo "\n";
echo "Received: ".$bitcoin->getreceivedbylabel("Your Address")."\n";
echo "</pre>";
</source>

'''Note:''' The jsonRPCClient library uses fopen() and will throw an exception saying "Unable to connect" if it receives a 404 or 500 error from bitcoind. This prevents you from being able to see error messages generated by bitcoind (as they are sent with status 404 or 500). The [https://github.com/aceat64/EasyBitcoin-PHP EasyBitcoin-PHP library] is similar in function to JSON-RPC PHP but does not have this issue.

== Java ==

The easiest way to tell Java to use HTTP Basic authentication is to set a default Authenticator:

<source lang="java">
final String rpcuser ="...";
final String rpcpassword ="...";

Authenticator.setDefault(new Authenticator() {
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication (rpcuser, rpcpassword.toCharArray());
}
});
</source>

Once that is done, [http://json-rpc.org/wiki/implementations any JSON-RPC library for Java] (or ordinary URL POSTs) may be used to communicate with the Bitcoin server.

== Perl ==

The JSON::RPC package from CPAN can be used to communicate with Bitcoin. You must set the client's credentials; for example:

<source lang="perl">
use JSON::RPC::Client;
use Data::Dumper;

my $client = new JSON::RPC::Client;

$client->ua->credentials(
'localhost:8332', 'jsonrpc', 'user' => 'password' # REPLACE WITH YOUR bitcoin.conf rpcuser/rpcpassword
);

my $uri = 'http://localhost:8332/';
my $obj = {
method => 'getinfo',
params => [],
};

my $res = $client->call( $uri, $obj );

if ($res){
if ($res->is_error) { print "Error : ", $res->error_message; }
else { print Dumper($res->result); }
} else {
print $client->status_line;
}
</source>

== Go ==

The [https://github.com/conformal/btcrpcclient btcrpcclient package] can be used to communicate with Bitcoin. You must provide credentials to match the client you are communicating with.

<source lang="go">
package main

import (
"github.com/conformal/btcnet"
"github.com/conformal/btcrpcclient"
"github.com/conformal/btcutil"
"log"
)

func main() {
// create new client instance
client, err := btcrpcclient.New(&btcrpcclient.ConnConfig{
HttpPostMode: true,
DisableTLS: true,
Host: "127.0.0.1:8332",
User: "rpcUsername",
Pass: "rpcPassword",
}, nil)
if err != nil {
log.Fatalf("error creating new btc client: %v", err)
}

// list accounts
accounts, err := client.ListAccounts()
if err != nil {
log.Fatalf("error listing accounts: %v", err)
}
// iterate over accounts (map[string]btcutil.Amount) and write to stdout
for label, amount := range accounts {
log.Printf("%s: %s", label, amount)
}

// prepare a sendMany transaction
receiver1, err := btcutil.DecodeAddress("1someAddressThatIsActuallyReal", &btcnet.MainNetParams)
if err != nil {
log.Fatalf("address receiver1 seems to be invalid: %v", err)
}
receiver2, err := btcutil.DecodeAddress("1anotherAddressThatsPrettyReal", &btcnet.MainNetParams)
if err != nil {
log.Fatalf("address receiver2 seems to be invalid: %v", err)
}
receivers := map[btcutil.Address]btcutil.Amount{
receiver1: 42, // 42 satoshi
receiver2: 100, // 100 satoshi
}

// create and send the sendMany tx
txSha, err := client.SendMany("some-account-label-from-which-to-send", receivers)
if err != nil {
log.Fatalf("error sendMany: %v", err)
}
log.Printf("sendMany completed! tx sha is: %s", txSha.String())
}
</source>

== .NET (C#) ==
The communication with rpc service can be achieved using the standard http request/response objects.
A library for serialising and deserializing Json will make your life a lot easier:

Json.Net ( http://james.newtonking.com/json ) is a high performance JSON package for .Net. It is also available via NuGet from the package manager console ( Install-Package Newtonsoft.Json ).

The following example uses Json.Net:

<source lang="csharp">
HttpWebRequest webRequest = (HttpWebRequest)WebRequest.Create("http://localhost.:8332");
webRequest.Credentials = new NetworkCredential("user", "pwd");
/// important, otherwise the service can't desirialse your request properly
webRequest.ContentType = "application/json-rpc";
webRequest.Method = "POST";

JObject joe = new JObject();
joe.Add(new JProperty("jsonrpc", "1.0"));
joe.Add(new JProperty("id", "1"));
joe.Add(new JProperty("method", Method));
// params is a collection values which the method requires..
if (Params.Keys.Count == 0)
{
joe.Add(new JProperty("params", new JArray()));
}
else
{
JArray props = new JArray();
// add the props in the reverse order!
for (int i = Params.Keys.Count - 1; i >= 0; i--)
{
.... // add the params
}
joe.Add(new JProperty("params", props));
}

// serialize json for the request
string s = JsonConvert.SerializeObject(joe);
byte[] byteArray = Encoding.UTF8.GetBytes(s);
webRequest.ContentLength = byteArray.Length;
Stream dataStream = webRequest.GetRequestStream();
dataStream.Write(byteArray, 0, byteArray.Length);
dataStream.Close();

WebResponse webResponse = webRequest.GetResponse();

... // deserialze the response
</source>

There is also a wrapper for Json.NET called Bitnet (https://sourceforge.net/projects/bitnet)
implementing Bitcoin API in more convenient way:

<source lang="csharp">
BitnetClient bc = new BitnetClient("http://127.0.0.1:8332");
bc.Credentials = new NetworkCredential("user", "pass");

var p = bc.GetDifficulty();
Console.WriteLine("Difficulty:" + p.ToString());

var inf = bc.GetInfo();
Console.WriteLine("Balance:" + inf["balance"]);
</source>

== Node.js ==

* [https://github.com/freewil/node-bitcoin node-bitcoin] (npm: bitcoin)

Example using node-bitcoin:

<source lang="javascript">
var bitcoin = require('bitcoin');
var client = new bitcoin.Client({
host: 'localhost',
port: 8332,
user: 'user',
pass: 'pass'
});

client.getDifficulty(function(err, difficulty) {
if (err) {
return console.error(err);
}

console.log('Difficulty: ' + difficulty);
});
</source>

Example using Kapitalize:

<source lang='javascript'>
var client = require('kapitalize')()

client.auth('user', 'password')

client
.getInfo()
.getDifficulty(function(err, difficulty) {
console.log('Dificulty: ', difficulty)
})
</source>

== Command line (cURL) ==

You can also send commands and see results using [http://curl.haxx.se/ cURL] or some other command-line HTTP-fetching utility; for example:

<source lang="bash">
curl --user user --data-binary '{"jsonrpc": "1.0", "id":"curltest", "method": "getinfo", "params": [] }'

{{merge|How to accept Bitcoin, for small businesses}}

Accepting Bitcoins is easy, and there are several ways to do it.

==Manually==
# Download a bitcoin client
# When a customer wants to buy something, send them a Bitcoin address where their payment should be sent.
#* You can do this by clicking "New.." next to your address in the Bitcoin client and sending that address to the customer.
# When payment comes in to that address, send the goods to your customer. Depending on the value of what you're selling, you may wish to wait until the payment shows Confirmed.
# To issue a refund, obtain from the customer the [[Address|bitcoin address]] where the refund payment should be sent. The refund address will likely be different from the address used when the customer sent payment, especially if an [[EWallet]] was used by the customer.

==Automated==
===Pre-generating Bitcoin addresses===
You can accept Bitcoins on your website without needing to use Bitcoin APIs or third party services if you pre-generate a large number of receiving Bitcoin addresses and store them in a database on your web server, and dispense them one-by-one to customers when they are ready to pay. This way, your web server never actually handles the bitcoins - it simply gives out addresses belonging to a wallet you maintain elsewhere. By using a unique address per order, you will always know which payment belongs to which order. [https://www.casascius.com Example of website using this method]

To pre-generate addresses, use a tool such as [[Pywallet]] (which can generate a wallet.dat file) or [[Bitcoin Address Utility]] (which can generate a CSV file). In both cases, you will be generating a list of [[Address|Bitcoin address]]es along with their corresponding [[private key]]s. Only the Bitcoin addresses (not the private keys) should be loaded on the web server.

If you are shipping goods manually, you can use the Bitcoin software to check for incoming payments, or alternately consider using [[Block Explorer]] or [[Abe]] to verify payment when you're about to ship. To make this easy, make your website provide you a full hyperlink that includes the proper receiving address: ht<nowiki>tp://www</nowiki>.blockexplorer.com/address/ADDRESSGOESHERE.

If you are delivering digital goods or services and want to be able to deliver instantly upon payment and/or confirmation, you can use a third-party service such as [[Bitcoin Notify]] to tell your website when a payment has been received. This sort of service requires no significant API implementation - they will simply make a POST to your website or send you an e-mail when a payment has been received on one of your addresses.

If you keep Bitcoins off your web server, this ensures your wallet cannot be stolen if your web server experiences a security intrusion. Your risk becomes limited to the possibility that a successful intruder could add his own addresses to your address pool and steal funds from a few incoming orders until you detect the problem, however, this is a relatively controllable risk.

===Using offchain payment networks===

[[Off-Chain_Transactions|Off chain]] networks provides various benefits to Bitcoin, such as instant confirmations and protection against double spending.

===Using a third-party plugin===
You can use an existing [[:Category:Shopping Cart Interfaces|shopping cart interface]] from a 3rd party to automatically handle all Bitcoin payments on your website. If you want to develop the system yourself, you can utilize the Bitcoin client's [[API tutorial (JSON-RPC)|JSON-RPC API]] to automatically accept payments.

Things to note if you build it yourself:
# When a customer orders something on your website it records:
#* Bitcoin address that payment should be sent to
#* Order details (delivery address etc.)
#* Customer's refund address (optional - if you wish you can ask for this later, only in cases a refund is required)
#* Payment amount
# When payment arrives, checks that they have paid the correct amount or not, and informs you
#* You dispatch the goods to the customer and mark the order as fulfilled
#* If you cannot dispatch the goods you mark the order as denied and ask the customer for a refund address (unless you already have it from earlier) to send a refund.
# Forwards the funds to bitcoin address of your choice

===If You have a retail business and do not have internet or smart phone===
You can still accept Bitcoin. [https://easybitz.com/merchant] EasyBitz.com has a very simple way to accept bitcoin with just a print out and a phone that gets sms text messages.

[[File:Easybitz bitcoin pointofsale.png|400 px|alt=Accept Bitcoin without internet|EasyBitz ZeroClick System|link=https://easybitz.com/merchant]]

===Businesses that mail invoices===
Does your business send out invoices to customers? Adding one line may make a huge impact for the Bitcoin economy. Perhaps you list it as a payment option just after Visa, MasterCard, and American Express, even if that means your customer must call or e-mail to make a payment. However it is possible to create automated invoices by using known payment systems supporting invoicing, and recurring invoice setup.

==Common Errors==
It has been observed on occasion that a business funnels all its orders through the same Bitcoin address, and asks people to send some BTC, then send email describing the timing and the amount of the transaction to 'claim' it. This is '''not''' secure, since anyone can see the transaction details using a tool such as [[Block Explorer]], and then try to claim someone else's transaction as theirs.

Do not do this. Give each customer a unique Bitcoin address.

==Listing your business on the Bitcoin Trade page==

Anyone can add and update a listing on the [[Trade|trade]] page. Just register if you haven't and add to the appropriate category. If you'ld like assistance, perhaps someone in the [http://webchat.freenode.net/?channels=#bitcoin-marketing #bitcoin-marketing] IRC channel would be willing to assist. If you have a brick and mortar business that accepts bitcoin you can add it to the bitcoin directories. [https://easybitz.com] [http://coinmap.org]

PHP developer intro

2014-10-30T14:10:18Z

Andy2993:

'''L'''inux '''A'''pache '''M'''ySQL '''P'''HP + Bitcoin tutorial.

For this introduction we assume that you have GNU/Linux server with Apache and PHP and that you wish to interact with the Bitcoin network from a web application. We assume some knowledge of Bitcoin and experience in PHP.

While this is written for PHP, the same principles apply for other languages. See the associated [[API reference (JSON-RPC)|API reference]] pages for info on other languages.

The easiest way to get started is to run Bitcoin in daemon mode with which PHP communicates via local HTTP requests. A library called [http://jsonrpcphp.org/ JSON-RPC] is used to call the various functions of bitcoind, which will respond back with a [http://en.wikipedia.org/wiki/Json JSON object].

== Setting up Bitcoin ==

You can download the Bitcoin daemon from the [[Main_Page|homepage]] and run one of the included binaries or compile your own from the included source code. See [[Running Bitcoin]] for details on configuring bitcoind.

Before running bitcoind you will need to create a configuration file in the Bitcoin data directory (~/.bitcoin/bitcoin.conf on Linux):
<source lang="bash">
rpcuser=user
rpcpassword={you MUST pick a unique password to be secure}
</source>
If you miss this step, bitcoind will remind you.

Now run bitcoind:
<source lang="bash">
$ ./bitcoind
# wait a few seconds for it to start up
$ ./bitcoind getinfo
# various information will be shown. If you get an error, try again until you see some useful output.
$ ./bitcoind help
# get help on commands, note no dash before help
</source>

Bitcoin will begin synchronizing with the network and downloading a complete copy of the block chain. As of August 2012, more than 2gb of data must be downloaded and verified during this process. It may take two or more hours to complete. You will know when it's done when the block count reaches the [http://blockexplorer.com/q/getblockcount current count].

== Getinfo (Bitcoind's version of Hello World) ==

Assuming Bitcoin has finished the initialisation process; download the file jsonRPCClient.php from [http://jsonrpcphp.org/ JSON-RPC PHP] and place it in a web-accessible location.

Second, create a PHP file with the following and visit it with your browser to test.

<source lang="php">
require_once 'jsonRPCClient.php';

$bitcoin = new jsonRPCClient('http://user:password@127.0.0.1:8332/');

echo "<pre>\n";
print_r($bitcoin->getinfo());
echo "</pre>";
</source>

'''Note:''' The jsonRPCClient library uses fopen() and will throw an exception saying "Unable to connect" if it receives a 404 or 500 error from bitcoind. This prevents you from being able to see error messages generated by bitcoind (as they are sent with status 404 or 500). The [https://github.com/aceat64/EasyBitcoin-PHP EasyBitcoin-PHP library] is similar in function to JSON-RPC PHP but does not have this issue.

== Precision ==

Bitcoin amounts can range from 1 Satoshi (0.00000001 BTC) to nearly 2,100,000,000,000,000 (21,000,000 BTC). To avoid rounding errors, you must make sure your PHP implementation supports the full range of Bitcoin values without losing precision. Most PHP implementations use IEEE 64-bit double-precision floating point numbers with 53 bits of precision, which is enough to correctly represent the full range of bitcoin values.

See [[Proper Money Handling (JSON-RPC)]] for more information.

If your PHP implementation does not support 64-bit numbers (again, this is very rare), you must use a version of bitcoind that sends values as strings (genjix maintains a fork at http://github.com/genjix/bitcoin) and use the [http://php.net/manual/en/ref.gmp.php GMP] and [http://php.net/manual/en/ref.bc.php BC Math] libraries for all calculations involving bitcoin amounts.

== Accounts ==

In Bitcoin, money is sent to addresses and many addresses can be held by one wallet. The balance shown by default in bitcoind is the sum of the bitcoins in all the addresses in the wallet.

Bitcoin goes another step. You can have [[Accounts explained|accounts]]. Each account holds multiple addresses and acts like a mini-bitcoind.

<source lang="bash">
$ ./bitcoind listaccounts
# show list of accounts and various info for each one
$ ./bitcoind getaccountaddress user889
# get an address to receive money to that is unique for the account user889
$ ./bitcoind getbalance user889
# get the sum of all the money in the addresses owned by the account user889
</source>

In your application, each user should have a unique username. You may then query bitcoind for a unique address using $bitcoin->getaccountaddress("user889"); [gets the first address for user889] or $bitcoin->getnewaddress("user889"); [creates a new address for user889].

The customer then deposits to this address.

You can check the funds for that customer by doing $bitcoin->getbalance("user889", 4);. The 4 indicates the minimum number of confirmations we will accept before assuming this payment is valid.

If you will be using accounts for multiple deposits and withdrawals long-term, you may want to consider tracking user balances in your own database. This simplifies transfers between your application's accounts and decouples your accounts from the Bitcoin wallet.

=== getnewaddress vs getaccountaddress ===

Using getnewaddress helps increase maintain anonymity of your users by making it hard for a malicious agent to track payments flowing through your application. Running getnewaddress too often, however, will cause your wallet to become filled with many empty addresses.

It is therefore recommended to in some way limit the number of unfunded addresses each user can request. Here is an example using sessions:
<source lang="php">
<?php
require_once('jsonRPCClient.php');
$bitcoin = new jsonRPCClient('http://root:root@127.0.0.1:8332/');
# now check for appropriate funds in user account
try {
$username = ...
if(isset($_SESSION['sendaddress']))
$sendaddress = $_SESSION['sendaddress'];
else {
$sendaddress = $bitcoin->getnewaddress($username);
$_SESSION['sendaddress'] = $sendaddress;
}
$balance = $bitcoin->getbalance($username);
}
catch (Exception $e) {
die("<p>Server error! Please contact the admin.</p>");
}
?>
</source>

This creates a new address at the beginning of every new session, and stores it in the session variable.

How to accept Bitcoin, for small businesses

2014-10-30T00:52:31Z

Andy2993:

{{merge|Merchant Howto}}

This guide is intended for small business owners who wish to help promote Bitcoin by accepting it as payment for goods and services. It's written with the assumption that you operate a regular business that sells goods or services for regular national currency such as dollars, and that you wish to accept Bitcoin as another legal way to pay, and that you intend to pay taxes on your Bitcoin income just like any other income.

With Bitcoin being touted as a way to conduct anonymous transactions and as way to compete with government currency, many small business owners wonder what's the right way to accept and account Bitcoin, or if it's legal or ethical, or whether and how they should pay taxes on income received through Bitcoin.

As far as we know, Bitcoin isn't yet formally recognized by governments and authorities as a "currency". But in practice, Bitcoin is likely no different than accepting payment in other forms, such as cash, or gold, or scrip, or gift cards or foreign currency. We think that it is pretty much the same as the local businesses of Great Barrington, Massachusetts choosing to accept their locally-printed [http://www.reuters.com/article/2007/06/19/us-usa-economy-berkshares-idUSN0530157720070619 "Berkshire Bucks"] to support their local economy.

====Starting to accept Bitcoin for transactions====
Accepting Bitcoin at a small business is best started in whichever manner keeps the accounting simple for you. This will vary by the type of business you are operating.

===Start with a sign===
[[{{ns:file}}:WeAcceptBitcoin.png‎]]

If you expect that the number of people interested in using Bitcoin is small, you might simply start by posting a sign or a note: "We Accept Bitcoin", and ask people to contact you directly in order to make a payment. Even if hardly anybody uses Bitcoin as a payment method, you're helping Bitcoin in two ways: one, by increasing awareness, and two, by making your customers more willing to accept Bitcoin as payment from others in the future, because now they know somewhere they can spend it.

===Utilize a merchant solution===
If you sell things on your website (goods or services), you'll want to use a [[#Merchant Services|Bitcoin merchant solution]] to accept the Bitcoins (you can usually opt to have them converted to USD or other currencies automatically with some services).

If you sell things in a brick and mortar shop, customers can pay using hardware terminals, touch screen apps or simple wallet addresses through QR Codes.

[[File:Easybitz bitcoin pointofsale.png|400 px|alt=Accept Bitcoin without internet|EasyBitz ZeroClick System|link=https://easybitz.com/merchant]]

[[File:Bitcoin-pos-terminal.png|200 px|alt=Bitcoin POS Terminal|Coinkite terminal]] [[File:Mobile_Web_App_Bitcoin_Register.jpeg|100 px|alt=Bitcoin POS Terminal|CoinBox terminal]]

[[File:Mobile_Checkout_Phone.png|200 px|alt=Bitcoin Mobile Checkout|BIPS Mobile Checkout|link=https://bips.me/point-of-sale]]

===Smart Phone or Tablet===
You can use a wallet address with any wallet. For that it's best if you can place a QR code near your cash register to which the customers can scan with their phone and pay (use http://ma.eatgold.com/accept to make a QR code sign). For a more convenient solution you can use a dedicated app or webapp that generates a QR code on the fly including the amount.

===Point-of-Sale hardware terminal===
With custom hardware you can integrate with existing registers and point-of-sales solutions (examples: [[File:Coinkite.gif|20px|link=https://coinkite.com/promo/wikibiz]] [https://coinkite.com/promo/wikibiz Coinkite], [https://xbterminal.com/ XBTerminal], [http://www.bitstraat.nl BitStraat]).

===Accounting===
When a customer makes a payment, you might simply issue a credit to their account. Ideally, you want to enter it in a way that suggests you received a payment. You could consider entering it as a "discount", but you may want to consider whether this inappropriately disguises the nature of the transaction. If on the other hand, you're giving "discounts" for Bitcoins, but then you are selling the Bitcoins for currency and then counting that as income, then chances are good that your calculation of income is making up for it. Ask your accountant.

===Businesses that offer gift cards===
If your business sells gift cards or gift certificates, you may find that the easiest way to accept Bitcoin is to accept it only for the purchase of gift cards, and then require the gift cards to be used for actual purchases of goods or services. This way, the accounting practices you already have in place for processing gift cards can be put to use. The accounting for Bitcoins would then be minimized to tracking sales of a single SKU.

This method is also ideal for retail food establishments and convenience stores, where the payment of Bitcoins through a mobile phone for a small daily food purchase might be cumbersome or disruptive, especially in front of a line of other customers. Bitcoins in this case would be best used to reload prepaid cards that can then be swiped at point-of-sale.

If you don't accept gift cards, but you already accept credit cards through a swipe terminal, consider the possibility that you could add a retail gift card system through the swipe terminal you already own. Many point-of-sale terminals, including ones from VeriFone®, are designed around the ability to support multiple applications on the same terminal. Gift cards are also highly profitable because of "breakage", or in other words, the fact that a significant percentage of them never get redeemed.

You could consider adding a private label gift card program from a provider who specializes in this, not just as a jumpstart to accepting Bitcoins, but as an extra boost to income. A private label gift card service provider necessarily have to handle your funds - they can simply provide a solution that keeps track of the balance on the cards on your behalf, including features that allow users to check their balances by phone or by web. Such a solution, of course, is also what makes the cards swipeable through the card reader.

===Businesses that mail invoices===
Does your business send out invoices to customers? Adding one line may make a huge impact for the Bitcoin economy. Perhaps you list it as a payment option just after Visa, MasterCard, and American Express, even if that means your customer must call or e-mail to make a payment.

If you have access to the programming expertise such that you can generate Bitcoin addresses programmatically, consider generating a brand new Bitcoin address for each invoice, and print it on the invoice. When a Bitcoin payment arrives, you'll automatically know where it should arrive.

Customers might wonder how much BTC they should pay in order to satisfy an invoice in full. Your invoice might suggest an amount. For example, if your invoice is for $100 and BTC's are currently worth $1.24 each, your invoice might suggest that it can be paid in full ''"with a payment of 80.65 BTC if paid by (date)"''.

You might be able to anticipate the possibility that even though a Bitcoin address can be printed on an invoice or payment stub, that they are very cumbersome for most people to type, especially being a mix of uppercase and lowercase letters. However, you should probably still do it anyway. The customer is probably going to want some paper trail for his payment. Giving him a pre-printed payment stub with a pre-printed address will satisfy that, because the customer can independently and publicly prove through [[Block Explorer]] that the payment took place.

Does your business have a website? On your invoice, consider allowing them to go to a special URL to get the address to make a Bitcoin payment just by typing in their invoice number. For example, ''ht<nowiki>tps://ww</nowiki>w.yoursite.com/paybtc'' with a form they can enter their invoice number, or just ''ht<nowiki>tps://ww</nowiki>w.yoursite.com/paybtc/60365'' for paying invoice #60365. This way, they can see the Bitcoin address, copy and paste it directly into their Bitcoin client.

Use a brand new address for each invoice whenever possible, and use it only once. This benefits the customer as it removes any ambiguity as to which customer is making which payment and for which invoice.

Online wallet supporting invoicing, subscriptions and recurrent payments, [https://www.xcoinmoney.com/info/sending-paying-invoices xCoinMoney]

===Avoiding fraud===

You should also consider the possible risk that fraudsters could send counterfeit invoices to your customers, and entice them to make a payment to a Bitcoin address they control, instead of you. While that isn't likely in general - it depends on how well a fraudster could find out who your customers are in the first place - it would certainly be an unpleasant situation if it ever happened. One way you could control that is, whenever possible, never let people try to type Bitcoin addresses off payment stubs - instead, force people to get the full Bitcoin address from your website via secure SSL. But, still print ''most'' of the address on the payment stub (perhaps with four or five characters starred out), so that the customer's need for a paper trail can be satisfied, so they can prove they paid if there is ever a dispute. Merchants can also use the IP address geolocation to understand the close proximity of users. There is automated solution such as [https://www.fraudlabspro.com FraudLabs Pro] that automates the screening of Bitcoin transactions to determine risk level.

==Setting Prices==

When a business accepts bitcoins for payment, there generally is the need to convert them to the currencies used for paying suppliers, employees and shareholders. Some merchants set prices based on the current market rate at the time the price quote is presented to the customer (merchant services like [[File:Polycoin_favicon.png|20px|link=http://www.polycoin.io]] [http://www.polycoin.io Polycoin], [[File:BIPS.gif|20px|link=https://bips.me]] [https://bips.me BIPS], [[File:Favicon-32x32_.png|20px|link=https://bitcoinpay.com]] [https://bitcoinpay.com BitcoinPay], [http://www.bit-pay.com Bit-pay], [https://coinbase.com Coinbase] or [http://paysius.com Paysius] do this automatically).

[[Bitcoin Prices]] lists the exchange rate for many currencies on multiple exchanges.

When prices are determined using an automated process, the current market rate can be based on either a current price or on a weighted average basis. [[Bitcoin Charts]] provides a [http://bitcoincharts.com/about/markets-api data feed that provides weighted prices]. [[Bitcoin Average]] also offers a weighted average price index, featuring average price across all exchanges reachable in the world and in over 150 currencies. 24h sliding average price index is also available and all data is [https://bitcoinaverage.com/api.htm reachable through the API].

When bitcoin funds for purchases are received, some merchants instantly exchange those proceeds into the preferred currency used (again done automatically by [[File:Polycoin_favicon.png|20px|link=http://www.polycoin.io]] [http://www.polycoin.io Polycoin], [[File:BIPS.gif|20px|link=https://bips.me]] [https://bips.me BIPS], [http://www.bit-pay.com Bit-pay], [https://coinbase.com Coinbase] or [[File:Favicon-32x32_.png|20px|link=https://bitcoinpay.com]] [https://bitcoinpay.com BitcoinPay]. Hedging for each transaction can nearly entirely eliminate exchange rate risk that the business is exposed to when accepting bitcoins for payment.

==Contract==

A sales contract might be used to ensure that specific terms are met to lessen the chances of a misunderstanding. For instance, the party sending payment is responsible for paying any [[transaction fee]] that might be necessary. A contract might specify that a transaction fee must be paid and what amount, so as to prevent the situation where the transaction is considered a low priority transaction and thus isn't confirmed quickly.

Other items that might be addressed in a contract:

* Requirement and handling of escrow through an [[:Category:Escrow_services|escrow service]].
* Jurisdiction for disputes.
* Refund policy (particularly with the exchange rate being volatile)

==Paying taxes on Bitcoin income==
[[Tax compliance]] is a topic of concern for small businesses. We aren't accountants or lawyers, and can't give legal or accounting advice.

But in many respects, Bitcoin transactions work very much like cash. Just like Bitcoin, cash is anonymous and doesn't leave a paper trail, yet is widely used in commerce every day.

Ask yourself how you would handle a cash transaction. Do you accept cash transactions? Do you normally pay taxes on cash transactions? The answer for Bitcoin should probably be the same.

As for how to decide what a Bitcoin transaction is worth... the IRS, as far as we know, has never issued a guide mentioning how to value Bitcoin transactions. But they probably have rules and guidelines on how to value transactions made in foreign currency or "cash equivalents". We imagine the accounting would be similar.

With Bitcoins, there's likely to be some difference between the value of BTC when you received them as payment, versus when you go to exchange them for another currency like USD, should you decide to do so. This scenario, likewise, would be no different if you accepted foreign currency or gold as payment. Under some scenarios, it might make sense to book the dollar value of BTC income as it is received, and then to book any difference incurred when it is exchanged for fiat currency. Under others, it might make sense to book the whole thing at the time of exchange.

Perhaps you might talk to your accountant. You don't need to get into a discussion with your accountant about block chains and private keys or the philosophy behind a decentralized currency. By comparing the fundamentals of Bitcoins to accounting concepts already well understood by the public, you can probably get all the answers you need. What would you ask your accountant if you decided that you wanted to accept ''Berkshire Bucks'' or 1-ounce gold coins as payment?

{{merge|How to accept Bitcoin, for small businesses}}

Accepting Bitcoins is easy, and there are several ways to do it.

==Manually==
# Download a bitcoin client
# When a customer wants to buy something, send them a Bitcoin address where their payment should be sent.
#* You can do this by clicking "New.." next to your address in the Bitcoin client and sending that address to the customer.
# When payment comes in to that address, send the goods to your customer. Depending on the value of what you're selling, you may wish to wait until the payment shows Confirmed.
# To issue a refund, obtain from the customer the [[Address|bitcoin address]] where the refund payment should be sent. The refund address will likely be different from the address used when the customer sent payment, especially if an [[EWallet]] was used by the customer.

==Automated==
===Pre-generating Bitcoin addresses===
You can accept Bitcoins on your website without needing to use Bitcoin APIs or third party services if you pre-generate a large number of receiving Bitcoin addresses and store them in a database on your web server, and dispense them one-by-one to customers when they are ready to pay. This way, your web server never actually handles the bitcoins - it simply gives out addresses belonging to a wallet you maintain elsewhere. By using a unique address per order, you will always know which payment belongs to which order. [https://www.casascius.com Example of website using this method]

To pre-generate addresses, use a tool such as [[Pywallet]] (which can generate a wallet.dat file) or [[Bitcoin Address Utility]] (which can generate a CSV file). In both cases, you will be generating a list of [[Address|Bitcoin address]]es along with their corresponding [[private key]]s. Only the Bitcoin addresses (not the private keys) should be loaded on the web server.

If you are shipping goods manually, you can use the Bitcoin software to check for incoming payments, or alternately consider using [[Block Explorer]] or [[Abe]] to verify payment when you're about to ship. To make this easy, make your website provide you a full hyperlink that includes the proper receiving address: ht<nowiki>tp://www</nowiki>.blockexplorer.com/address/ADDRESSGOESHERE.

If you are delivering digital goods or services and want to be able to deliver instantly upon payment and/or confirmation, you can use a third-party service such as [[Bitcoin Notify]] to tell your website when a payment has been received. This sort of service requires no significant API implementation - they will simply make a POST to your website or send you an e-mail when a payment has been received on one of your addresses.

If you keep Bitcoins off your web server, this ensures your wallet cannot be stolen if your web server experiences a security intrusion. Your risk becomes limited to the possibility that a successful intruder could add his own addresses to your address pool and steal funds from a few incoming orders until you detect the problem, however, this is a relatively controllable risk.

===Using offchain payment networks===

[[Off-Chain_Transactions|Off chain]] networks provides various benefits to Bitcoin, such as instant confirmations and protection against double spending.

===Using a third-party plugin===
You can use an existing [[:Category:Shopping Cart Interfaces|shopping cart interface]] from a 3rd party to automatically handle all Bitcoin payments on your website. If you want to develop the system yourself, you can utilize the Bitcoin client's [[API tutorial (JSON-RPC)|JSON-RPC API]] to automatically accept payments.

Things to note if you build it yourself:
# When a customer orders something on your website it records:
#* Bitcoin address that payment should be sent to
#* Order details (delivery address etc.)
#* Customer's refund address (optional - if you wish you can ask for this later, only in cases a refund is required)
#* Payment amount
# When payment arrives, checks that they have paid the correct amount or not, and informs you
#* You dispatch the goods to the customer and mark the order as fulfilled
#* If you cannot dispatch the goods you mark the order as denied and ask the customer for a refund address (unless you already have it from earlier) to send a refund.
# Forwards the funds to bitcoin address of your choice

===If You have a retail business and do not have internet or smart phone===
You can still accept Bitcoin. [https://easybitz.com/merchant] EasyBitz.com has a very simple way to accept bitcoin with just a print out and a phone that gets sms text messages.

[[File:Easybitz bitcoin pointofsale.png|400 px|alt=Accept Bitcoin without internet|EasyBitz ZeroClick System|link=https://easybitz.com/merchant]]

===Businesses that mail invoices===
Does your business send out invoices to customers? Adding one line may make a huge impact for the Bitcoin economy. Perhaps you list it as a payment option just after Visa, MasterCard, and American Express, even if that means your customer must call or e-mail to make a payment. However it is possible to create automated invoices by using known payment systems supporting invoicing, and recurring invoice setup.

==Common Errors==
It has been observed on occasion that a business funnels all its orders through the same Bitcoin address, and asks people to send some BTC, then send email describing the timing and the amount of the transaction to 'claim' it. This is '''not''' secure, since anyone can see the transaction details using a tool such as [[Block Explorer]], and then try to claim someone else's transaction as theirs.

Do not do this. Give each customer a unique Bitcoin address.

==Listing your business on the Bitcoin Trade page==

Anyone can add and update a listing on the [[Trade|trade]] page. Just register if you haven't and add to the appropriate category. If you'ld like assistance, perhaps someone in the [http://webchat.freenode.net/?channels=#bitcoin-marketing #bitcoin-marketing] IRC channel would be willing to assist. If you have a brick and mortar business that accepts bitcoin you can add it to the bitcoin directories. [https://easybitz.com] [http://coinmap.org]
