Regular check of subscription status for IAP

Hi, For a user who subscribed a product via In-App Purchase, how does the application backend know that the user is still subscribed?

The initial purchase happens on the mobile app. Via receiving and validating the receipt of initial purchase, the backend of mobile app would be informed.

However, what is the appropriate option for the subsequent subscription payments? How do I know whether the user is still paying?

Thanks.

Great question, we recommend using App Store Server Notifications V2, designed for this very purpose. They inform your server directly when things like renewals occur. (https://developer.apple.com/documentation/appstoreservernotifications)

  • Thanks a lot for the response. Does this architecture "retry" a notification if it cannot deliver the message in the first try?
