Example project demoing App Store Server Notifications.
Check the .env.example file for initial setup.
Run the app via pnpm start and then setup a tunnel using ngrok.io or tunnel.dev for the configured port number.
Add https://some.domain/webhooks/apple as a sandbox URL for the app at https://appstoreconnect.apple.com/apps/{id}/appstore/info. Note that you will need to setup a (dummy) subscription for the app to see the option.
Finally, you can run curl -X POST http://localhost:4000/webhooks/apple/send-test to trigger a notification and see it logged.
