Subscription across multiple applications

We are working on App Bundles which will allow In-App purchases across multiple apps. Our goal is to identify whether the transaction is successful on the renewal date without opening the app.

It can be done by validating the receipts but how to check the same if the application is not launched.

How to detect the auto-renewal from another app which is of same App Bundle?

Here are the resources we referred:
WWDC Video
Apple Documnetation
Validating Receipts with the App Store
App Bundle

Has anyone implemented the same?
