Registrar Modules allow you to create modules that allow for the registration and management of domain names in WHMCS.

The sample files here demonstrates how a registrar module for WHMCS should be structured and exercises all supported functionality.

For more information, please refer to the documentation at:

https://developers.whmcs.com/domain-registrars/

Clone the sample registrar module locally:

git clone [email protected]:WHMCS/sample-registrar-module.git

Rename the module directory and file to your desired module name:

mv modules/registrars/registrarmodule/registrarmodule.php modules/registrars/registrarmodule/newmodule.php
mv modules/registrars/registrarmodule/ modules/registrars/newmodule/

Open the newmodule.php file and replace all occurencies of registrarmodule_ with the new name, in this instance newmodule_.

Login to the WHMCS Admin Area and navigate to Setup > Products > Domain Registrars to activate.

The recommended structure of a registrar module is as follows.

 registrarmodule/
  |- lib/
  |- templates/
  |- tests/
  |  hooks.php
  |  logo.png
  |  registrarmodule.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.

We strongly encourage you to write unit tests for your work. Within this SDK we provide a sample unit test based upon the widely used PHPUnit.
