Return values explained

Return Values Explained

When you make a call to the API, the result of the call will be output into the body of the HTTP response. The response is split into two or three sections using the  | (pipe) character. For example:

OK|1268316443|http://pfi.me/0/XXXXXXX

A successful response will always begin with OK. Error responses will begin with ERROR.

The second section of the string reports the ID of the transaction in our platform. This will be posted to you with every subsequent HTTP POST callback. We recommend that you interpret this value as a 64-bit integer to avoid integer overflow issues.

The final section is the URL to which you must redirect your end user (HTTP 302).
