We currently have a google checkout buynow button on our website that we use to take new signups for our business. We have to MANUALLY "activate" someone's account after receiving their payment and it's a pain. We would like to AUTOMATE this process by having google send back some variables to our php code and make this an automated process. Anyone that knows how to do this will be rewarded greatly. Act fast as this is an IMMEDIATE NEED! Thank you!
