Payment Gateway modules allow you to integrate payment solutions with the WHMCS platform.
The sample files here demonstrate how we suggest a Bank Gateway that uses a remotely hosted payment page should be created for WHMCS.
For more information, please refer to the documentation at: https://developers.whmcs.com/payment-gateways/remote-input-gateway/
A remote input bank module is a type of gateway that accepts input of pay method data remotely within an iFrame so that it appears transparent to the end user, and then exchanges it for a token that is returned back to WHMCS to be stored for future billing attempts.
Within WHMCS, sensitive payment data such as a bank account number is not stored locally when a remote input module is used.
For the purposes of this sample, a demo of a remotely hosted payment page is
provided within the demo directory.
In a real world scenario, this file/page would be hosted by the payment gateway being implemented. On submission they would validate the input and return the user to the callback file with a success confirmation.
The recommended structure of a remote input bank gateway module is as follows.
modules/gateways/
|- callback/remotebank.php
| remotebank.php
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.
