Data API Code Snippets

1. Create a project in the API Console and set up credentials for a web application. Set the authorized JavaScript origins to identify the URL from which you'll be sending requests (e.g. http://localhost).

2. Copy the full code sample to a local file accessible to your web server (e.g. /var/www/html/example.html).

3. Find the line in the code sample that sets the client ID to be used for the request, and replace the value with the client ID for your credentials:

   gapi.client.init({
       'clientId': 'REPLACE_ME',

4. Open the file in your browser (e.g. http://localhost/example.html). It is recommended to use a browser with a debugging console, such as Google Chrome.

5. Authorize the request if necessary. If the request is authorized, the debugging console should display the API response to the request as a JSON object.

Prerequisites

• Node.js must be installed.
• The npm package management tool (comes with Node.js).
• The Google APIs Client Library for Node.js:

  npm install googleapis --save

• Access to the internet and a web browser.
• A Google account.

Set up your project and run code samples

1. Create a project in the API Console and set up OAuth 2.0 credentials in the Google API Console. When setting up your credentials, set the application type to Other.

2. Save the client_secret.json file associated with your credentials to a local file.

3. Copy the full code sample to a local file in the same directory as the client_secret.json file (or modify the sample to correctly identify that file's location.

4. Run the sample from the command line:

   node sample.js

5. Most samples print something to STDOUT or, for web application examples, to the web page you're viewing. You can also check the YouTube website to see the effects of requests that write data, such as requests that create playlists or channel sections.

Prerequisites

• Python 2.6 or greater
• The pip package management tool
• The Google APIs Client Library for Python:

  pip install --upgrade google-api-python-client

• The google-auth, google-auth-oauthlib, and google-auth-httplib2 for user authorization.

  pip install --upgrade google-auth google-auth-oauthlib google-auth-httplib2

• The Flask Python web application framework (if you are running the Python samples for web server applications).

  pip install --upgrade flask

• The requests HTTP library.

  pip install --upgrade requests

Set up your project and run code samples

1. Create a project in the API Console and set up OAuth 2.0 credentials in the Google API Console. When setting up your credentials, set the application type to Web application for samples that use the Flask Python web application framework and also set authorized redirect URIs for those credentials. Otherwise, set the application type to Other.

2. Save the client_secret.json file associated with your credentials to a local file.

3. Copy the full code sample to a local file in the same directory as the client_secret.json file (or modify the sample to correctly identify that file's location.

4. Run the sample from the command line:

   python sample.py

   Note for web server application examples:
   
   If you are running the Python samples for web server applications, then running the script starts a local web server. To actually execute the API request, you need to go to the served web page in a browser. For example, the Python samples that use the Flask web application framework contain a line like this:
   
   app.run('localhost', 8080, debug=True)
   
   This code starts a local web server at http://localhost:8080. However, the script doesn't try to execute an API request until you actually navigate to http://localhost:8080 in a browser. (The URL for your local server must also be set as an authorized redirect URI for your authorization credentials.)

5. Most samples print something to STDOUT or, for web application examples, to the web page you're viewing. You can also check the YouTube website to see the effects of requests that write data, such as requests that create playlists or channel sections.

Prerequisites

• PHP 5.4 or greater with the command-line interface (CLI) and JSON extension installed.
• The Composer dependency management tool.
• The Google APIs Client Library for PHP:

  php composer.phar require google/apiclient:^2.0
