I have a Google Marketplace app that uses a service account for access user's drive account. It requires domain wide grants,
As per the doc here: https://developers.google.com/+/domains/authentication/delegation
""" If the service account is listed as an app on the Google Apps Marketplace, then domain-wide access to user data is granted during the installation of that app. """
However I cannot find a way to specify the service account id in my app, how do I make sure that the service account is indeed granted privileges when the admin installs the app
