A python client library for Google Play Services OAuth.

gpsoauth

Python client library for Google Play Services OAuth.

gpsoauth allows python code to use the "master token" flow that KB Sriram described at http://sbktech.blogspot.com/2014/01/inside-android-play-services-magic.html.

import gpsoauth

email = 'example@gmail.com'
password = 'my-password'
android_id = '0123456789abcdef'

master_response = gpsoauth.perform_master_login(email, password, android_id)
master_token = master_response['Token']

auth_response = gpsoauth.perform_oauth(
    email, master_token, android_id,
    service='sj', app='com.google.android.music',
    client_sig='...')
token = auth_response['Auth']

This can be useful when writing code that poses as a Google app, like gmusicapi does here.

Many thanks to Dima Kovalenko for reverse engineering the EncryptedPasswd signature in https://web.archive.org/web/20150814054004/http://codedigging.com/blog/2014-06-09-about-encryptedpasswd/.

For an explanation of recent changes, see the changelog.

Alternative flow

There is an alternative login flow if you are experiencing BadAuthentication errors.

1. Go to https://accounts.google.com/EmbeddedSetup
2. Log into your Google Account
3. Click on "I agree" when prompted
4. Obtain the value of the oauth_token cookie. For more details see the gpsoauth-java readme.

Then, perform the token exchange:

import gpsoauth

email = 'example@gmail.com'
android_id = '0123456789abcdef'
token = '...' # insert the oauth_token here

master_response = gpsoauth.exchange_token(email, token, android_id)
master_token = master_response['Token']  # if there's no token check the response for more details

auth_response = gpsoauth.perform_oauth(
    email, master_token, android_id,
    service='sj', app='com.google.android.music',
    client_sig='...')
token = auth_response['Auth']
