We have a product we are using paypal to pay. BUT, we need to get info from paypal indicating that they paid. It works if the customer waits for the paypal message to redirect them to our page.. but many people click away and it doesn't get updated on our mysql server. I simply need someone to get us using paypal's IPN so that it calls a simple php page that updates the record indicating that they paid. Shouldn't take someone longer then an hour, but just need someone to go through the steps and get it working.
