So I am having a bit of trouble here. See I need to have a script on a web page update a database after a successful transaction, but I cant just have the paypal redirect to the script after the completed transaction other wise the purchaser could somehow scam the php script. I know php to a decent degree but I dont want to go and learn the whole paypal api just to figure this bugger out.
Anyone wanna give me a hand, I am pretty sure its just a little snippet of code or something.
