PayPal's Agreement API not sending notification on payments
I am trying to set up recurring payments for licenses using PHP.
I am using PayPal's Agreement API. Everything "seems" to be working correctly. I am in sandbox mode and I am being redirected to the ReturnURL successfully. However, I am not receiving notifications for the payments made.
The system is going to be set up to receive payment notifications on a monthly basis. Upon receipt of this notification, the license will be extended.
