WalletBit/API/Send

Send to Email or Bitcoin address

$fields = array(
  'merchant' => 'owner@example.com',
  'customer_email' => 'johnsmith@example.com',
  'address' => '',
  'amount' => 0.01000000,
  'details' => 'You got Bitcoins!'
);
$fields['encrypted'] = strtoupper(hash('sha256', $fields['merchant'] . ':' . $fields['customer_email'] . ':' . $fields['amount'] . ':' . 'API Key'));

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'https://walletbit.com/api');
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, TRUE);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, TRUE);
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch, CURLOPT_POST, count($fields));
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($fields));
$response = curl_exec($ch);
curl_close($ch);

if ($response == '1')
{

}

If 'customer_email' is not on WalletBit, it will try to send to the defined bitcoin address.
