For paypal express payment (the one pay via a paypal account), I am quite happy to provide a return url and handle the payment in a paypal page. (so the transaction doesn't happen in my site).
If I want to accept credit card payments, I saw some APIs that I can pass credit card number from my site to paypal. Is it possible that I can just provide a return url and go to a paypal page? On that page, my user can type in credit card number and payment details. So I won't have to worry if my site is secure with those financial data.
Many Thanks
