Android Publisher API 购买订阅获得 403

Question

I'm trying to validate receipts using Google's API, but I am running into an issue where hitting this request.

https://www.googleapis.com/androidpublisher/v3/applications/packageName/purchases/subscriptions/subscriptionId/tokens/token

returns "The project id used to call the Google Play Developer API has not been linked in the Google Play Developer Console."

but

https://www.googleapis.com/androidpublisher/v3/applications/packageName/inappproducts

returns the list of products which makes me believe I have authorization right, but just can't pinpoint why I can't get individual subscriptions.

Answer 1

I had to go into that product, make a small change, and saved. That fixed the API.
