I have a portal, that requires monthly subscription.
But upon making the first payment, we would require a IPN verification to automatically update our system.
What my concers are is:
User logs in as username: Member1 - he makes payments - redirects to paypal - Paypal send info to my Site - IPN verification - Update Database
We would like to know how can we pass the value of the Member at the end so that we can update the database to indicate that this member made the payment.
