Hi I am using pay pal for the first time for a client. Can anyone advise if pay pal returns any variables in get or post to advise that the payment was successful. The system is for purchasing credits and obviously can use my own page to return to from pay pal. But how do you get the info that the payment was successful and also check that it came from papal so that people can't just type in the url and add credits themselves. Thanks
You will need to integrate with the paypal API. Check out their integration part of their site. There are several pre0built scripts that will help you integrate into your website. http://www.paypal.com/integration
