Hello,
We are considering using the Advanced Commerce API for a native macOS app distributed through the Mac App Store.
Our use case is a base auto-renewable subscription with optional subscription add-ons (e.g. Effects and Templates).
The Advanced Commerce API eligibility page lists Mac Catalyst, but does not explicitly list native macOS.
However, the macOS 15.4 release notes mention support for Advanced Commerce API purchases in StoreKit.
Could someone please clarify:
-
Is Advanced Commerce API supported for native macOS App Store apps (not Mac Catalyst), including subscriptions with optional add-ons?
-
Does it support introductory free trials, e.g. a 3-day free trial for the base subscription?
-
Can existing auto-renewable subscription subscribers be migrated to Advanced Commerce API and then purchase optional add-ons as part of the same subscription?
Many thanks!
