I have set up a service account for my google calendar api project. The idea is that my web site can connect to my google calendar and display events, etc. As it was put by google
Service account clients are created when domain-wide delegation is
enabled on a service account.
Which indeed happened and so I have a connecting OAuth 2.0 client ID. So far so good. I generated a json file that I used to connect and try to authenticate using this code
from cal.models import Cal as Caldb
import httplib2
from apiclient.discovery import build
from oauth2client.file import Storage
from oauth2client.client import OAuth2WebServerFlow
from oauth2client import tools
from calendar import monthrange
from calendar_gui import MyCalendar
from datetime import datetime
from datetime import date
from django.utils.safestring import mark_safe
from oauth2client.service_account import ServiceAccountCredentials
import os
from django.conf import settings
def authenticate():
scope= ['https://www.googleapis.com/auth/calendar']
credentials = ServiceAccountCredentials.from_json_keyfile_name(os.path.join(settings.PROJECT_ROOT, '../', 'myjson.json'), scopes=scope)
delegated_credentials = credentials.create_delegated('email@email.com')
http = httplib2.Http()
http = delegated_credentials.authorize(http)
service = build(serviceName='calendar', version='v3', http=http, credentials=credentials)
return service
But alas
service = build(serviceName='calendar', version='v3', http=http, credentials=credentials)

I have enabled the google calendar api. In fact, I feel like I've followed all of the steps. In fact, I've done this once before with complete success, but I'm perplexed now. I read that maybe I need to wait 24-48 hours before this all takes effect. Could it be as simple as that?
For right now, I'm just testing this locally. Nothing pushed to the server yet.
