I completed In App Purchase for Android. Play API give me purchase token, package name and product id.
But i try verification API and then api give me error.
I create a new service account in Google Developer Console and i linked from API Access to Google Play Developer Console. I try the API (https://developers.google.com/android-publisher/api-ref/rest/v3/inappproducts/get) but still same error:
The project id used to call the Google Play Developer API has not been linked in the Google Play Developer Console.
