Handling billing notification events
Because in-app purchases are completed through Apple’s interface, your app needs a way to detect when a user performs actions such as subscribing to or canceling a plan. Apple StoreKit sends server-side billing notifications whenever these events occur. This step ensures your app’s backend is correctly connected to Apple’s billing system.
Click Connect billing notification events. This automatically registers the correct endpoint URL for your app with Apple StoreKit.
It can take up to five minutes for Apple to update and recognize the new endpoint.
If you encounter an error, confirm that your API key has admin access. See this article for instructions.
Testing setup
1
Send test notification
Click Send test notification. Make sure at least five minutes have passed since connecting the billing notification events.

If an error occurs, check App Store Connect → Apps → App Information → App Store Server Notifications.
