Hello all, As an example, I've seen arcade websites where one can pay $5 and instantly receive 5 "game credits" on their arcade account. I'm thinking Paypal runs an external script right after it confirms payment or something. What I want to do is the following: 1) Person makes a $10 donation 2) Automatically adds their username to a donation list I don't want to have to do such things manually. Something along those lines. Is this even possible?
Yes, it is possible and fairly simple. You will want to integrate your website with paypal using the IPN or a more advanced payment API's. I personally like their express checout method. https://www.paypal.com/IntegrationCenter/ic_expresscheckout.html Here's Paypal's integration center: https://www.paypal.com/IntegrationCenter/ic_home.html There are a number of free and paid scripts available to help you integrate with these, or if it's within your budget it would be easy to find someone that can do the integration for you.
