I have searched PayPal, Google, and Bing for details regarding Payment Data Transfer (PDT) and subscriptions, without result.
My question is, For each recurrence of a subscription payment will I receive a PDT request?
I understand that the first PDT is requested/initiated by the payer's browser. For subsequent payments though, will PayPal initiate a PDT request, or will I have to create an Instant Payment Notification (IPN) endpoint?
