Gateway Developer Guide and Reference 07 January 2014 13
Preface
This guide describes the data parameters for the Gateway payments solutions.
Scope
This guide is a reference to the payment card data parameters available for submitting in
transaction requests over the Gateway to multiple supported processors. It also covers the
resulting response data parameters and errors.
The guide describes the requirements of an ever growing list of processing platforms. It
organizes parameters into a core set of request parameters supported by all processors,
additional parameters unique to individual processors, and purchasing card parameters
specialized to monitor credit card use in businesses. It also provides a section on response
parameters and error codes (PNREF values that are not 0).
Although this guide provides guidance on getting started with the SDK, setting up credit card
processing, and testing your integration, its broad scope does not lend to use as a tutorial on
integration. Refer to the
PayPal Developer website and the Classic APIs - Payflow Gateway SDK
for detailed working examples and use cases.
