ReleaseNotes

Namecheap.com WHMCS Registrar plug-in is an open-source plug-in that is distributed free of charge. It focuses on integrating Namecheap as a domain registrar at WHMCS.

After the integration you can setup Namecheap as the default registrar for your customers and decide which services and TLDs to offer to your customers from within the WHMCS admin area.

Pre-requisites

• Access to WHMCS admin area.
• An understanding of Namecheap’s environments.
• Namecheap account with API access enabled on the desired environment.

NOTE: Namecheap has a production as well as a test server environment. The test server environment is called Sandbox. We urge you to test the WHMCS Registrar plug-in in our sandbox environment, before pointing it to production. For more detailed information, please visit the developer's site at http://developer.namecheap.com.

Create a folder called namecheap under Modules/Registrar in your WHMCS root directory and paste the downloaded namecheap.php and namecheapapi.php files inside the folder (the namecheap.php and namecheapapi.php files are located inside the downloaded archive).
