service account (403) Forbidden Google Play In-app Billing Purchase Status API

Answer 1

I just solved this problem.

You must add the service account email ("1048550291137-rfqol5nm4k9tqr0a5bupedoakhd184k4@developer.gserviceaccount.com") in your google play publish page(https://play.google.com/apps/publish/, not the google developer console).

at "Settings"-"User account & rights", "Invite new user", submit with service account email, check the "View financial reports" right, then everythings works ok~
