Paypal Express Checkout Setup

I'm setting up Paypal Express Checkout with CS-cart 4.0 and have a few questions. The API user name and password to be entered are my business Paypal username/password, correct? Do I want to choose signature or certificate verification? Prefix is just to identify source of tranasction on statements, correct? Thanks for any insights.

You will find info there.[/font][/color]



The above is if you choose PayPal express checkout as your processor.

Thanks! That helps a lot. Going with Paypal express.
