What is the Ratepay Payment Gateway 1.8?

The Ratepay Gateway 1.8 is a synchronous web interface that implements the services essential for enabling online shops to use Ratepay’s payment products. The Ratepay Gateway receives XML requests sent by the online shop via the HTTP POST method, processes them and returns an appropriate XML response. The Gateway response always contains a processing result which indicates the success or failure of the request and determines which subsequent operations are allowed.

The Gateway requests and responses are UTF-8 encoded XML documents which are formally specified as a set of XML schema files (XSDs). This document provides a supplementary description of the data structures defined by the XML schema files.
