Attach payment by cards from PayPal to the site for individuals. persons from Kazakhstan perhaps?

Question

PayPal

A man contacted me today. Wants to create a mini-online store that accepts card payments. He offered to go to the banks and conclude an acquiring agreement. He says that he has no legal status, the usual physical. face, and with physical Banks do not enter into agreements with individuals. Previously, I connected only payments from banks. I read that in paypal you can create a physical account. face and accept payments from cards via API. I read in the documentation that for Go live it is available only for the Business account. Send and receive money is available for Personal account. As far as I understand Personal account, you can simply go in and register on the system's website itself. Next, to use the API, I need to create credentials. And then I can connect the payment system to the site using their api? Since I don’t have a paypal account myself, I want to clarify where to go to “dig” further?
