Can you tell me the steps to integrate paypal Api to a website?

If you know the difference between PayPal Ipn and PayPal Api please explain briefly.

Please help me. i want to integrate PayPal api for a single product. how i can do it. if you give me some instruction to integrate it then it would be very helpful for me. If you know it please help me.:blush:

What you are asking is a very complex and involved question dependent on many unknown factors. Though the place to start of with anything relating to Paypal integration would be the Paypal Developer API Docs. The developer docs explain public facing interface to communicate directly with Paypal via programmatic means.

Edit: ipn is a feature (instant payment notification) where as – api is an (application programming interface)

Instant Payment Notification (IPN) allows to integrate paypal payments with your website’s backend operations, so you get immediate notification and authentication of the PayPal payments you receive.

Application Programming Interfaces (API) offers you direct credit card payment processing capability through PayPal. For credit card transactions, customers stay on your website as PayPal processes the payment in the background.
