So the signature is now made starting from your relative path + NUL character + post data (which must include your nonce!).


This is how it was done for version 1:
* fast ticker
http://data.mtgox.com/api/2/BTCUSD/money/ticker_fast


You have your params(post_data) = the word nonce, followed by the actual ''nonce'' integer (params = [(u'nonce',nonce)])
and
http://data.mtgox.com/api/2/BTCUSD/money/ticker_fast?pretty


You have your header made up of ''Rest-Key'' (your API-KEY) and ''Rest-Sign'' (a hashed signature)

Rest-Sign is created by doing : base64encode( HMAC hash( base64decoded(API-secret), the nonce, with SHA512 digest))


'''What differs in version 2 is now''' : BEFORE the nonce, you are adding the '''relative path you are requesting'''(ie: BTCUSD/money/ticker) '''+ a NUL char (ascii code 0)'''.

So in my python code below which is very readable you can see everything remains the same as API v1 except now we are using api2postdatatohash = path + chr(0) + post_data          #new way to hash for API 2, includes path + NUL.

API Version 2:

The V2 API URL is:

https://data.mtgox.com/api/2/

Documentation

Unofficial documentation (So far the best we have) is provided at : https://bitbucket.org/nitrous/mtgox-api/overview (The bitcointalk forum link is: https://bitcointalk.org/index.php?topic=164404.0 )

Official docs are on: https://github.com/MtGox/mtgox-doc

Differences between v1 and v2:
  • The URL is now something along the lines of BTCUSD/money/order/add instead of BTCUSD/private/order/add in api1. All current known methods are found in the money category.
  • The requested path must now be included when you compute your hashed signature (Rest-Sign) for added security.

    In version 1, Rest-Sign is created through base64-encoding the 256-digest HMAC hashing of your post data (which of course must include your nonce) with your API secret, previously base64 decoded. Now in version 2, you must simply add before your post data the relative path you are requesting (anything after the /api/2/ base, ie: BTCUSD/money/ticker), concatenated with a NUL character (ASCII code 0). So the signature is now made starting from your relative path + NUL character + post data (which must include your nonce!).
  • fast ticker

and

Explanation of Methods

BTCUSD/money/order/quote
<@MagicalTux> it estimate the result of running an order at a given price based on market depth
BTCUSD/money/ticker_fast
Solves the problem of ticker lag. (supposedly)
