I implemented PayPal app w/webhook using REST API and JS SDK for my customer which has "gone live".
The customer also has a legacy IPN handler registered w/PayPal, still in use, especially for prior made subscriptions.
Purchases/Subscriptions made in the live "new app" via REST API/JS SDK unfortunately also cause IPN messages to be delivered to the legacy IPN handler (with types of 'cart' or 'recurring_payment' ).
Ideally, I don't want new sales via REST/JS SDK to generate IPN messages to the legacy IPN handler, as it will cause confusion as to what is a new purchase and what is a legacy purchase. I can track new sales via webhook, so why is PayPal generating IPN message for the new API???
Is there a way to prevent delivery of these "new API" sales as IPN messages to the legacy IPN handler?
