Complete the steps described in the rest of this page, and in about five minutes you'll have a simple Python command-line application that makes requests to the YouTube Data API.The sample code used in this guide retrieves the
channelresource for the GoogleDevelopers YouTube channel and prints some basic information from that resource.
To run this quickstart, you'll need:
- Python 2.6 or greater.
- The pip package management tool.
- Access to the internet and a web browser.
- A Google account.
Step 1: Turn on the YouTube Data API
- Use this wizard to create or select a project in the Google Developers Console and automatically turn on the API. Click Continue, then Go to credentials.
- On the Add credentials to your project page, click the Cancel button.
- At the top of the page, select the OAuth consent screen tab. Select an Email address, enter a Product name if not already set, and click the Save button.
- Select the Credentials tab, click the Create credentials button and select OAuth client ID.
- Select the application type Other, enter the name "YouTube Data API Quickstart", and click the Create button.
- Click OK to dismiss the resulting dialog.
- Click the (Download JSON) button to the right of the client ID.
- Move this file to your working directory and rename it
Step 2: Install the Google Client Library
Run the following command to install the library using pip:
pip install --upgrade google-api-python-client
See the library's installation page for alternative installation options.
Step 3: Set up the sample
Create a file named
quickstart.py in your working directory and paste in the
# Sample Python code for user authorization import httplib2 import os import sys from apiclient.discovery import build from apiclient.errors import HttpError from oauth2client.client import flow_from_clientsecrets from oauth2client.file import Storage from oauth2client.tools import argparser, run_flow # The CLIENT_SECRETS_FILE variable specifies the name of a file that contains # the OAuth 2.0 information for this application, including its client_id and # client_secret. CLIENT_SECRETS_FILE = "client_secret.json" # This OAuth 2.0 access scope allows for full read/write access to the # authenticated user's account and requires requests to use an SSL connection. YOUTUBE_READ_WRITE_SSL_SCOPE = "https://www.googleapis.com/auth/youtube.readonly" API_SERVICE_NAME = "youtube" API_VERSION = "v3" # This variable defines a message to display if the CLIENT_SECRETS_FILE is # missing. MISSING_CLIENT_SECRETS_MESSAGE = "WARNING: Please configure OAuth 2.0" # Authorize the request and store authorization credentials. def get_authenticated_service(args): flow = flow_from_clientsecrets(CLIENT_SECRETS_FILE, scope=YOUTUBE_READ_WRITE_SSL_SCOPE, message=MISSING_CLIENT_SECRETS_MESSAGE) storage = Storage("%s-oauth2.json" % sys.argv) credentials = storage.get() if credentials is None or credentials.invalid: credentials = run_flow(flow, storage, args) # Trusted testers can download this discovery document from the developers page # and it should be in the same directory with the code. return build(API_SERVICE_NAME, API_VERSION, http=credentials.authorize(httplib2.Http())) args = argparser.parse_args() service = get_authenticated_service(args) ### END BOILERPLATE CODE # Sample python code for channels.list def channels_list_by_username(service, **kwargs): results = service.channels().list( **kwargs ).execute() print('This channel\'s ID is %s. Its title is %s, and it has %s views.' % (results['items']['id'], results['items']['snippet']['title'], results['items']['statistics']['viewCount'])) channels_list_by_username(service, part='snippet,contentDetails,statistics', forUsername='GoogleDevelopers')
Step 4: Run the sample
Run the sample using the following command:
The sample will attempt to open a new window or tab in your default browser. If this fails, copy the URL from the console and manually open it in your browser.
If you are not already logged into your Google account, you will be prompted to log in. If you are logged into multiple Google accounts, you will be asked to select one account to use for the authorization.
- Click the Accept button.
- The sample will proceed automatically, and you may close the window/tab.
- Authorization information is stored on the file system, so subsequent executions will not prompt for authorization.
- The authorization flow in this example is designed for a command-line application. For information on how to perform authorization in a web application, see Using OAuth 2.0 for Web Server Applications.

AttributeError: 'Module_six_moves_urllib_parse' object has no attribute 'urlparse'
This error can occur in Mac OSX where the default installation of the "six"
module (a dependency of this library) is loaded before the one that pip
installed. To fix the issue, add pip's install location to the
system environment variable:
Determine pip's install location with the following command:
pip show six | grep "Location:" | cut -d " " -f2
Add the following line to your
<pip_install_path>with the value determined above:
~/.bashrcfile in any open terminal windows using the following command:
TypeError: sequence item 0: expected str instance, bytes found
This error is due to a bug in
httplib2, and upgrading to the latest version
should resolve it:
pip install --upgrade httplib2
