Server notifications v2

You can probably begin here: https://developer.apple.com/documentation/appstoreservernotifications/app_store_server_notifications_v2

Thank you for your recommendation. I read this documentation and many more but I can not find information about what types of In-App purchases we should receive server notifications for.

For example, documentation says we can receive notification with type SUBSCRIBED that can also have subtype INITIAL_BUY, which means the user either purchased or received access through Family Sharing to the subscription for the first time. ( https://developer.apple.com/documentation/appstoreservernotifications/notificationtype#possibleValues )

While we receive this type of notification for Auto-Renewable Subscription I would also expect to receive this notification for Non-Renewing Subscription as well, which is not the case.

Also when I check subscriptions of my sandbox user it does not show Non-Renewing Subscriptions even though purchase was successfull and it is listed in the latest_receipt_info of notification body.

The purpose of Server notifications are to receive updates on transactions and status changes that can occur outside of your app - such scenarios only apply to auto-renewing subscriptions(ARS). While for the other IAP types, its primarily limited to refunds and access changes due to Family Sharing.

Can you share the benefit of receiving a server notification for a purchase of a non-renewing subscription (NRS)? Is there anything you found that gave you the impression you should expect a notification for a NRS?

Note: The subscriptions management page applies only to ARS, as a customer needs to be able to cancel that subscription and if applicable, change the level of service. While that doesn't apply to a NRS, therefore is not visible on that page.
