To start using your PayPal PayFlow Pro account with rwAuction Pro, set PayPal PayFlow Pro as your Merchant Account Gateway in the administration control panel under Billing and Fees > Credit Cards. The following settings are required:
PayFlow User - If you set up one or more additional users on the account, this value is the ID of the user authorized to process transactions. If, however, you have not set up additional users on the account, USER has the same value as VENDOR. This value is case-sensitive.
PayFlow Vendor - Your vendor is the Login ID or merchant login you created when you
signed up for PayPal Merchant Services. The user is also the vendor,
unless you have created additional accounts (users) within PayPal
Manager.
PayFlow Partner - Your Partner depends on how you registered for your PayFlow account. If
you purchased your account from PayPal's website or sales department,
your Partner ID is PayPal, VeriSign, VSA, or CyberCash. If you
purchased it from a reseller, contact the reseller for your Partner ID.
This value is case-sensitive.
PayFlow Password - The 6- to 32-character password that you defined while registering for the account. This value is case-sensitive.
