I'm really struggling with trying to use Service Account authentication to use the Google Directory API (Admin SDK).
Using client based three legged OAuth this works (tested here - https://developers.google.com/admin-sdk/directory/v1/reference/members/insert) but there's a problem with the permission delegation to the service account I am using. Under the Google Apps administration, I enabled using APIs and added the service account to the list of allowed OAuth clients as instructed.
Here is the code:
import httplib2
import sys
from apiclient.discovery import build
from oauth2client.client import SignedJwtAssertionCredentials
credentials = SignedJwtAssertionCredentials(
'<KEY>@developer.gserviceaccount.com',
'<KEY DATA>',
scope='https://www.googleapis.com/auth/apps.groups.settings https://www.googleapis.com/auth/admin.directory.group https://www.googleapis.com/auth/admin.directory.group.member'
)
http = httplib2.Http()
http = credentials.authorize(http)
service = build("admin", "directory_v1", http=http)
groups = service.groups()
g = groups.get(groupKey="<GROUP NAME>").execute()
Eventually, I get the following error:
apiclient.errors.HttpError: <HttpError 403 when requesting https://www.googleapis.com/admin/directory/v1/groups/<GROUP NAME>?alt=json returned "Not Authorized to access this resource/api">
I tried using the following API as well:
service = build("groupssettings", "v1", http=http)
But this returns an error as well - "Backend Error".
