title: Error posting new Google domains activity
body: <p>I have used this guide: <a href="https://developers.google.com/+/domains/quickstart/python" rel="nofollow noreferrer">Quick start for Python</a>.</p>
  
  <p>I also have created an G-Suite account to access to Google Apps domain control panel.</p>
  
  <p>Here my code to insert a post:</p>
  
  <pre><code>__author__ = 'joannasmith@google.com (Joanna Smith)'
  
  import httplib2
  import pprint
  
  from apiclient.discovery import build
  
  from oauth2client.service_account import ServiceAccountCredentials
  
  
  
  SERVICE_ACCOUNT_EMAIL = 'servizio@projecttest-161515.iam.gserviceaccount.com'
  
  
  
  SERVICE_ACCOUNT_PKCS12_FILE_PATH = './ProjectTest-9179fae1c392.json'
  
  
  USER_EMAIL = 'its2016web@assicuraora.com'
  
  
  SCOPES = ['https://www.googleapis.com/auth/plus.me','https://www.googleapis.com/auth/plus.stream.write']
  
  
  def authenticate():
  
    print 'Authenticate the domain for %s' % USER_EMAIL
  
  
    credentials = ServiceAccountCredentials.from_json_keyfile_name(
      SERVICE_ACCOUNT_PKCS12_FILE_PATH, scopes=SCOPES)
  
    delegate_credentials = credentials.create_delegated(USER_EMAIL)
  
    http = httplib2.Http()
    http = delegate_credentials.authorize(http)      
    return build('plusDomains', 'v1', http=http)
  def activitiesInsert(service):
  
    user_id = 'me'
  
  
    print('Insert activity')
    result = service.activities().insert(
        userId = user_id,
        body = {
            'object' : {
                'originalContent' : 'Happy Monday! #caseofthemondays'
            }
            'access' : {
                'items' : [{
                    'type' : 'domain'
                }],
                'domainRestricted': True
            }
        }).execute()
    print('result = %s' % pprint.pformat(result))
  
  
  if __name__ == '__main__':
    service = authenticate()
    activitiesInsert(service)
  </code></pre>
  
  <p>To retrieve ClientID I have to check "Enable delegation on the whole domain G Suite" on Service account keys, and I also have added scopes to client ID from Google Apps domain control panel.</p>
  
  <p>But when I run my code it output this error:  </p>
  
  <blockquote>
    <p>&lt;HttpError 403 when requesting
    <a href="https://www.googleapis.com/plusDomains/v1/people/me/activities?alt=json" rel="nofollow noreferrer">https://www.googleapis.com/plusDomains/v1/people/me/activities?alt=json</a>
    returned "Forbidden"></p>
