I think that I just may be confused by PayPal's tendency to frequently change the names of their services, plus maybe their web interface now.
According to the Version 3.2 nopCommerce User Manual, there are 2 types of PayPal accounts: PayPal Standard and Pay Pal Direct.
My client has "PayPal PayFlow Pro", so I'm following the instructions in the User Manual for the Direct service. The User Manual says to go to My Account > Profile > API Access, but when I'm logged into the PayPal account, those aren't choices. There is an Account Administration section, but it doesn't provide a Profile.
In fact, I can't find anywhere in the PayPal website to obtain Profile OR API Access.
Can anybody give instructions on how to use PayPal's new website?
