Google APIs Node.js Client

This is Google's officially supported node.js client library for using OAuth 2.0 authorization and authentication with Google APIs.

Questions/problems?

• Ask your development related questions on
• If you've found an bug/issue, please file it on GitHub.

Installation

This library is distributed on npm. To add it as a dependency, run the following command:

m install google-auth-library --save

Application Default Credentials

This library provides an implementation of Application Default Credentials for Node.js.

The Application Default Credentials provide a simple way to get authorization credentials for use in calling Google APIs.

They are best suited for cases when the call needs to have the same identity and authorization level for the application independent of the user. This is the recommended approach to authorize calls to Cloud APIs, particularly when you're building an application that uses Google Compute Engine.

Download your Service Account Credentials JSON file

To use Application Default Credentials, You first need to download a set of JSON credentials for your project. Go to APIs & Auth > Credentials in the [Google Developers Console](developer console) and select Service account from the Add credentials dropdown.

This file is your only copy of these credentials. It should never be committed with your source code, and should be stored securely.

Once downloaded, store the path to this file in the GOOGLE_APPLICATION_CREDENTIALS environment variable.

Enable the API you want to use

Before making your API call, you must be sure the API you're calling has been enabled. Go to APIs & Auth > APIs in the [Google Developers Console](developer console) and enable the APIs you'd like to call. For the example below, you must enable the DNS API.

Call an API

As long as you update the environment variable below to point to your JSON credentials file, and the fill in the placeholder variables from your project, the following snippet should work.

google = require('googleapis');
GoogleAuth = require('google-auth-library');

authFactory = new GoogleAuth();
dns = google.dns('v1');

Factory.getApplicationDefault(function(err, authClient) {
 (err) {
console.log('Authentication failed because of ', err);
return;

 (authClient.createScopedRequired && authClient.createScopedRequired()) {
var scopes = ['https://www.googleapis.com/auth/cloud-platform'];
authClient = authClient.createScoped(scopes);


r request = {
// TODO: Change placeholders below to values for parameters to the 'get' method:

// Identifies the project addressed by this request.
project: "",
// Identifies the managed zone addressed by this request. Can be the managed zone name or id.
managedZone: "",
// The identifier of the requested change, from a previous ResourceRecordSetsChangeResponse.
changeId: "",
// Auth client
auth: authClient


s.changes.get(request, function(err, result) {
if (err) {
  console.log(err);
} else {
  console.log(result);
}
;
