I was wondering if anyone could help me out with how to go about accepting recurring payments via paypal with IPN.
I'm currently thinking of doing the express checkout option, and I am using Zend Framework.
Some questions I NEED answered:
- What information must I store in the database?
- Client wants to implement a referrer rewards system: if you refer a paying friend you get one month free; is this possible?
- Can you at least outline the API calls I need to implement to get this working or even better provide me with examples?
