PayPal subscriptions PDT / IPN - PLEASE

Question

Am having a lot of trouble getting my head around this paypal payment stuff...

How can i confirm that the user has successfully signed up for my subscription

Answer 1

If you want to implement Paypal IPN and your customers don't use same email from my experience you can use a form to authenticate the user

• user login on your website with xxx@example.org
• user clicks on your item and pays with yyy@example.org
• after he pays you can redirect him to a form where they can merge Paypal account with website account
• every time that user pays then your IPN will be covered by the information he provided
• you should save his payment information for later use.
