Paypal Auto Creditor

[Coly010]

Ok so I created a few buttons on paypal to manage my in game purchases.

My problem is that I've never worked with an auto creditor system before, so what I'm asking is how do I find out from paypal that the player paid the money, so that I can credit them the pack. I have the button return the item number of the pack, which it does using $_GET. So far I've it set up so that it credits the user based on $_GET and I thank god the game is not live because people could just fake it.

Any help is appreciated.

I think paypal has an api for this. You could look into that.

Am I right in thinking IPN is what I'm looking for?

Probably. I've never focused much on it because I use Dave's Donation mod.

I really can't get my head round any of this.

I have set up Express Checkout, it was working for the sandbox accounts, but then once I swapped it to the live accounts it says I need to sign up to accept Digital Goods, which I can't find a link to anywhere. On the documentation it tells me to click the Get Started button. When I do nothing happens.

I've tried setting up buttons, but I can't find a way to securely find out if the transaction was completed so the code can credit the user.

MCCode's come's with an IPN file. Paypal also provide's an IPN PHP file.

Use those in your application. They already have the methods to check a payment is completed.
