This is rather confusing. I'm trying to set up PayPal as my payment gateway. I've run into some confusion and need help. In WHMCS it is asking for API Username API Details are required for Refunds and Subscription cancellations API Password API Signature When I go to the PayPal site I don't see any of this. They provide two items (which I won't list here) Client ID Secret I don't want to be guessing on this as I want it to work right the first time. Now I'm inclined to believe that API username and API Password are the username and password I log into PayPal would that make the ClintID the API Signature? I'd really appreciate any assistance. Thanks.
