anybody who have an experienced with online payment with paypal? im planning to make a website with online payment which accepts credit cards..i want it connected to paypal since paypal is my payment gateway..i want it like, after the customers fill -up some form fields they will be taken to another page like payment information where they will enter their credit card number, but my problem is how do i get the response from payment so that my program knows that credit card is valid or not..so its like if the credit card is not valid then it will go to a diffrent page then if it is valid then it will go to another page..but how do i get the response from paypal? anybody have an experience with this..thanks alot.
