Steps to reproduce the behavior

I have the below code snippet to handle subscription purchase

// On button press
requestPurchase(sku);

// Purchase updated listener
this.purchaseUpdateSubscription = purchaseUpdatedListener((purchase) => {
      console.log('purchaseUpdatedListener', purchase);
      const receipt = purchase.transactionReceipt;
      await finishTransaction(purchase);
      await Firebase.updateUser({
        'subscription.ios': purchase
      })
    });

So far I was able to perform purchase and store the receipt onto Firebase. But my question is do I need to call getAvailablePurchases on every app launch to store the latest purchase receipt? Or do I only need to store the receipt when the user purchases the subscription for the first time? Also, how do I validate if the subscription has expired?

This is usually done using webhooks. For Apple you can enable server-to-server notifications that will communicate with your server. Google has something similar, but setting it up is much more complicated and there is no docs on that. Android Developers has a basic doc here, but what you want is a Pub/Sub system that google has.

Also this StackOverflow question has some good information

UPDATE I actually found a good source that will help you to set up server-to-server notifications. RevenueCat Docs has a lot of useful information. Here is the link for Apple and Google Pub/Sub
