(Don't bid if you are not familiar with playstore in-app purchase. And you must show your experience related playstore in-app purchase)
I have android application.
I have implemented in-app purchase function of android app.
But I need to receive real-time updates from the playstore of user's integration.
For example, if the user cancels subscription, then need to receive status on nodejs backend.
Cancel, renew, resubscription,...
You have to do necessary setting and implement nodejs backend to receive in-app subscription update.
