Where can I get API username and password for WHMCS plugin?

To setup the WHMCS plugin you need to enter your API username and password, which can be done in the:

 WHMCS Module Settings > CloudLinux Licenses.

• Please note, that access to the CloudLinux API is available to the reseller level accounts only.

The "username" here is your cln.cloudlinux.com login.

The "password" is the IP's registration token from the profile at https://cln.cloudlinux.com/clweb/account/profile.xhtml
