New to v2 is the "Payment Description" field, which allows WHMCS administrators to specify the payment description shown on the payment screen of PayPal and Coinbase. The available "variables" are...

  • %COMPANY_NAME% - The name of your company (The company name specified in WHMCS's settings)
  • %CLIENT_ID% - The unique id of the client's WHMCS account
  • %CLIENT_DISPLAY_NAME% - The display name as configured by the client's public pay settings
  • %CLIENT_HASH_ID% - The client's unique public pay hash id

The above "variables" will be replaced with the correct values at runtime.
