Addon Modules

From WHMCS Documentation

(Redirected from Addons)

Addon modules allow developers to extend the functionality of WHMCS further including new pages in the admin or client areas. You can enable, disable, and manage them in the WHMCS Admin Area.

You can access this feature at Configuration () > System Settings > Addon Modules or, prior to WHMCS 8.0, Setup > Addon Modules.

You can find addons to download and install in the WHMCS Marketplace.

  1. Click Activate for the addon you wish to enable.
  2. Click Configure.
  3. If the addon has includes module-specific settings, configure them.
  4. Select the administrator roles to allow to access the addon in the Access Control section.
  5. Click Save Changes.

The addon will now appear in the Addons menu.
