Promotions can be a valuable tool to increase user engagement or attract new users by offering content or features to a limited number of users free of charge.
We are happy to share an improvement in the Google Play Developer API that makes it easier to track your promotions from your own backend. Starting today, the API for Purchases.products will return "
Promo" as a new value for the field
purchaseType when the user redeems a promo code. Now, the possible values are:
0. Test(test purchases)
1. Promo(Promo code redemption purchase)
For purchases made using the standard in-app billing flow, the field will continue to not be set in the API response.
