Hi all, We are several developers to experience issue with in-app purchases & promotion: if the promotion is used inside the app instead of the standard payment method, the returned developer payload is empty. A post has been opened on Stack Overflow: http://stackoverflow.com/questions/34979420/in-app-purchases-made-via-promo-codes-return-empty-developer-payload-string
I asked the Google Play Developer Support ([email protected]) but the answer I received is globally "there is no bug". Moreover, as commented in a comment by user greywolf82, when you use the promotion via the Google Play store, this purchase can't have a developer payload so it may be a serious security flaw if we can't check the developer payload validity. So, does anyone have a valid developer payload after using a promotion code? -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
