How to authorise a gdata contacts client in python

I'm trying to use Google Contacts API to add a entry to the user's contacts. I've managed to use OAuth2 and get access token and make an authorised request to Google Contacts API. But I did it manually, a simple GET to https://www.google.com/m8/feeds/contacts/default/full. I want to use gdata so I don't have to manually create the xml.

The problem is I cannot authorise the gdata's ContactsClient.

From the doc:

gd_client = gdata.contacts.client.ContactsClient(source='YOUR_APPLICATION_NAME')
# Authorize the client.

But how do I authorise it? The example uses email ans password to create an authorised ContactsClient

self.gd_client = gdata.contacts.client.ContactsClient(source='GoogleInc-ContactsPythonSample-1')
self.gd_client.ClientLogin(email, password, self.gd_client.source)

And so far I haven't found how to authorise the gdata client. I did found that I can pass a gdata.gauth.ClientLoginToken to gdata.contacts.client.ContactsClient, but it didn't work as well

auth_token = gdata.gauth.ClientLoginToken(credentials.access_token)
gd_client = gdata.contacts.client.ContactsClient(
     source='project-id',
     auth_token=auth_token)
contact = create_contact(gd_client)

I get a 401 - Unauthorized "There was an error in your request. That's all we know"

This create_contact comes from the doc

Using example @dyerad indicated and the spinet for create contacts on the Google Contacts API doc I created the example code below.

I just had to fix a wee error on the create_contact snippet I took from the doc. You should use

    # Set the contact's postal address.
    new_contact.structured_postal_address.append(gdata.data.StructuredPostalAddress(
        rel=gdata.data.WORK_REL, primary='true',
        street=gdata.data.Street(text='1600 Amphitheatre Pkwy'),
        city=gdata.data.City(text='Mountain View'),
        region=gdata.data.Region(text='CA'),
        postcode=gdata.data.Postcode(text='94043'),
        country=gdata.data.Country(text='United States')))

instead of

# Set the contact's postal address.
new_contact.structured_postal_address.append(
  rel=gdata.data.WORK_REL, primary='true',
  street=gdata.data.Street(text='1600 Amphitheatre Pkwy'),
  city=gdata.data.City(text='Mountain View'),
  region=gdata.data.Region(text='CA'),
  postcode=gdata.data.Postcode(text='94043'),
  country=gdata.data.Country(text='United States'))

Here is the full code:

import flask
import httplib2
from oauth2client import client
from logging import info as linfo
import atom.data
import gdata.gauth
import gdata.data
import gdata.contacts.client
import gdata.contacts.data

app = flask.Flask(__name__)

client_info = {
    "client_id": "<CLIENT_ID>",
    "client_secret": "<CONTACTS_CLIENT_SECRET>",
    "redirect_uris": [],
    "auth_uri": "https://accounts.google.com/o/oauth2/auth",
    "token_uri": "https://accounts.google.com/o/oauth2/token"
}

scopes = 'https://www.google.com/m8/feeds/'


def create_contact(gd_client):
    new_contact = gdata.contacts.data.ContactEntry()
    # Set the contact's name.
    new_contact.name = gdata.data.Name(
        given_name=gdata.data.GivenName(text='Elizabeth'),
        family_name=gdata.data.FamilyName(text='Bennet'),
        full_name=gdata.data.FullName(text='Elizabeth Bennet'))
    new_contact.content = atom.data.Content(text='Notes')
    # Set the contact's email addresses.
    new_contact.email.append(gdata.data.Email(address='[email protected]',
                                              primary='true',
                                              rel=gdata.data.WORK_REL,

    new_contact.email.append(gdata.data.Email(address='[email protected]',
                                              rel=gdata.data.HOME_REL))
    # Set the contact's phone numbers.
    new_contact.phone_number.append(gdata.data.PhoneNumber(text='(206)555-1212',

    # Set the contact's IM address.
    new_contact.im.append(gdata.data.Im(address='[email protected]',

    # Send the contact data to the server.
    contact_entry = gd_client.CreateContact(new_contact)
    linfo('Contact\'s ID: %s' % contact_entry.id.text)
    return contact_entry
