How can I get real-time subscription notification to my server if there is a change in subscription or when there is an in-app puchase.
Thanks for posting! At the moment, there is no mechanism to notify you automatically whenever the status of an IAP item changes.
The only option related to verification of IAP, is the Receipt Verification Service (RVS) as described here: https://developer.amazon.com/docs/in-app-purchasing/iap-rvs-for-android-apps.html
