How to get started with WHMCS on Zapier

Connect to WHMCS on Zapier

WHMCS uses basic authentication to authenticate your account on Zapier.

  • Enter your WHMCS username and password for an administrative user to authenticate. Zapier recommends creating a separate API user for better activity tracking.
  • The host should be your fully qualified domain name without a trailing slash at the end. For example, "" (without the quotes). 
  • While IP allowlisting is not available for API access due to our backend's dynamic nature, you can secure your connection with an API key.
