Prior to starting development, I wanted to verify that this integration of custom tenders would be approved by Clover + not violate the app market policies.
We want to create a Clover app that listens for incoming orders from a third-party REST API. These orders will already be paid using a different service, since we're going to make the use of the Clover app optional. On receiving and accepting an order in the Clover app, the order would then be created using the Clover REST API + marked as paid via a custom tender.
This sounds like it would adhere to the app market policies, since there are no in-app payments and app acquirement would be free. However, this comment introduced some doubt and wanted to hear from someone at Clover just to make sure:
