PayFlow - Credentials
We're using PayPal PayFlow Pro but in the wizard, WA asks for 4 pieces of info when that is selected: Partner, Merchant Login, User and Password.
If I try using the live manager.paypal.com credentials, it fails. If I use the test credentials using my sandbox account on PayPal, they don't offer those 4 credentials, just the 3 credentials: Username, Password and Signature.
There are just too many places this could go wrong and any insight into this would be appreciated.
