This guide will walk you through the steps to integrate your Helcim Commerce account with WHMCS.

Before getting started you will need the following:

Download the Module


  • WHMCS 7.4
  • Helcim Commerce account with gateway feature enabled. Please contact us to have this feature enabled on your account.
  • The Helcim module for WHMCS (link above)

Notice Regarding Security

While this module uses tokenization for card storage due to the way WHMCS is currently designed there are instances where local storage will be used. WHMCS will only call the storeremote function after a client has at least one invoice set to the Helcim Gateway. This is currently a feature request with WHMCS, more information can be found at:
