This is more of a request for information on how to proceed.
We already have an approved app in the App Marketplace. We are building a new SaaS stack in EU and need event notifications from our EU customers to go to a different notification endpoint (the new data center in EU). I assume that this would require a new Marketplace App, but is it possible to duplicate an existing app and make changes to only the notification endpoint?
I’m also assuming that this is the easiest way to do this because I cannot see a way of segregating the data from EU and non-EU customers by adding a new notification event subscription with a different endpoint. Is that possible?
