I am developing a member site (PHP) where we will be taking subscription payments from users. For this, we are using PayPal - to which I am new to. Have set up the sandbox test accounts, and have set the IPN option and specifiied a url.
Now I want to test the IPN and set up tables in my database to save information each order/subscription.
Am finding the PayPal documentation is lacking, and have looked into various classes which can handle the IPN posts. All without success! I see there have been some posts here on the subject, but am still struggling.
If I am using a IPN script do I need to set the IPN url in the sandbox at all?
We would also need to deal with unsubscribes in any IPN script.
