I'm looking into integrating PayPal REST API to be used on a web site that sells subscriptions. The tricky part is that my web site has an affiliate program which is tracked by a separate vendor's affiliate tracking system. So when a payment is processed by PayPal, a notification of this event needs to be sent to the affiliate tracking system. The affiliate vendor system can handle Paypal IPN (Instant Payment Notification) but I don't believe it can handle Paypal webhooks. I want to write my code to use Paypal's REST API or hopefully a .Net SDK that wraps the REST API (if available).
From reading PayPal's documentation, I've gathered that PayPal supports two kinds of notifications: IPN and webhooks. I've gathered that the following tools support only certain notification methods:
Paypal buttons. NVP API, SOAP API -> supports IPN
REST API -> supports webhooks
So my question is: can the REST API generate IPN or perhaps can I make the webhooks look like IPN so my affiliate tracking system sees the IPN messages that it recognizes?
