-There are two types of gateway module:
-
-* Third Party Gateways - these are payment solutions where checkout occurs
-on a remote website, usually hosted by the payment gateway themselves.
-
-* Merchant Gateways - these are payment solutions where credit card details
-are collected - usually within the WHMCS application, though more and more
-often this will be done remotely, typically via an iframe, with a page hosted
-remotely by the payment gateway enabling tokenised storage.
-
-The sample files here demonstrate how we suggest a Third Party Payment Gateway
-module for WHMCS be structured and implemented.
