Yes, Apple App Store sends notification events of subscription state changes in the JSON format. You can receive these notifications or webhook events from the Apple App Store by configuring your server URL in App Store Connect.
Please ensure these notifications are also passed by your server to Chargebee using the same JSON format, to maintain uniform subscription status in Chargebee.
