I'm trying to get access to a particular recurring Google Calendar Meeting from a Service Account. The owner of the Calendar Meeting is a real user and created in their personal calendar (which can't be changed at this point). Sharing the entire Google Calendar of that user with the Service Account is not a viable solution.
Instead I've tried to just invite the Service Account to the meeting - so far so good.
However, I'm unable to retrieve that event with the Google Calendar API. Basically, I'm trying something like this:
scopes = ["https://www.googleapis.com/auth/calendar.readonly"]
google_credentials = ServiceAccountCredentials.from_json_keyfile_name(CREDENTIALS_FILE, scopes)
calendar_service = build("calendar", "v3", credentials=google_credentials)
events_result = calendar_service.events().list(
# calendarId="<some-service-account>@<some-project>.iam.gserviceaccount.com",
calendarId="primary",
singleEvents=True,
).execute()
print(events_result)
events = events_result.get("items", [])
print(events)
Neither getting the calendar with id primary nor with the <some-service-account>@<some-project>.iam.gserviceaccount.com works.
Also getting the calendar list of the service account looks like that:
scopes = ["https://www.googleapis.com/auth/calendar.readonly"]
google_credentials = ServiceAccountCredentials.from_json_keyfile_name(CREDENTIALS_FILE, scopes)
calendar_service = build("calendar", "v3", credentials=google_credentials)
print(calendar_service.calendarList().list().execute())
# OUTPUTS:
# {'kind': 'calendar#calendarList', 'etag': '"<removed>"', 'nextSyncToken': '<removed>', 'items': []}
Thus, an empty items list. I'm not sure what the problem is here - or if that's not even possible.
Am I missing some permissions for the Service Account?
