Payment Gateway modules allow you to integrate payment solutions with the WHMCS platform.
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 Tokenised Payment Gateway module for WHMCS be structured and implemented.
For more information, please refer to the documentation at: https://developers.whmcs.com/payment-gateways/
A tokenised module is a type of merchant gateway that accepts input of pay method data locally and then exchanges it for a token that is stored locally for future billing attempts.
Within WHMCS, sensitive payment data such as a card number is not stored locally when a tokenisation module is used.
The recommended structure of a merchant gateway module is as follows.

For the latest WHMCS minimum system requirements, please refer to https://docs.whmcs.com/System_Requirements
We recommend your module follows the same minimum requirements wherever possible.
