Hello Analytics API: JavaScript quickstart for web applications

This tutorial walks through the steps required to access a Google Analytics account, query the Analytics APIs, handle the API responses, and output the results. The Core Reporting API v3.0, Management API v3.0, and OAuth2.0 are used in this tutorial.

Step 1: Enable the Analytics API

To get started using Google Analytics API, you need to first use the setup tool, which guides you through creating a project in the Google API Console, enabling the API, and creating credentials.

Create a client ID

From the Credentials page:

  1. Click Create Credentials and select OAuth client ID.
  2. Select Web application for APPLICATION TYPE.
  3. Name the credential.
  4. Set the AUTHORIZED JAVASCRIPT ORIGINS to http://localhost:8080
  5. Set the AUTHORIZED REDIRECT URIS to http://localhost:8080/oauth2callback
  6. Click Create.

Step 2: Setup the sample

You'll need to create one file named HelloAnalytics.html, which will contain the HTML and JavaScript code for our example.

  1. Copy or download the following source code to HelloAnalytics.html.
  2. replace '<YOUR_CLIENT_ID>' with your client ID. created above.
<!DOCTYPE html>
  <meta charset="utf-8">
  <title>Hello Analytics - A quickstart guide for JavaScript</title>

<button id="auth-button" hidden>Authorize</button>

<h1>Hello Analytics</h1>

<textarea cols="80" rows="20" id="query-output"></textarea>


  // Replace with your client ID from the developer console.

  // Set authorized scope.
  var SCOPES = ['https://www.googleapis.com/auth/analytics.readonly'];

  function authorize(event) {
    // Handles the authorization flow.
    // `immediate` should be false when invoked from the button click.
    var useImmdiate = event ? false : true;
    var authData = {
      client_id: CLIENT_ID,
      scope: SCOPES,
      immediate: useImmdiate

    gapi.auth.authorize(authData, function(response) {
      var authButton = document.getElementById('auth-button');
      if (response.error) {
        authButton.hidden = false;
      else {
        authButton.hidden = true;

function queryAccounts() {
  // Load the Google Analytics client library.
  gapi.client.load('analytics', 'v3').then(function() {

    // Get a list of all Google Analytics accounts for this user

function handleAccounts(response) {
  // Handles the response from the accounts list method.
  if (response.result.items && response.result.items.length) {
    // Get the first Google Analytics account.
    var firstAccountId = response.result.items[0].id;

    // Query for properties.
  } else {
    console.log('No accounts found for this user.');

function queryProperties(accountId) {
  // Get a list of all the properties for the account.
      {'accountId': accountId})
    .then(null, function(err) {
      // Log any errors.

function handleProperties(response) {
  // Handles the response from the webproperties list method.
  if (response.result.items && response.result.items.length) {

    // Get the first Google Analytics account
    var firstAccountId = response.result.items[0].accountId;

    // Get the first property ID
    var firstPropertyId = response.result.items[0].id;

    // Query for Views (Profiles).
    queryProfiles(firstAccountId, firstPropertyId);
  } else {
    console.log('No properties found for this user.');

function queryProfiles(accountId, propertyId) {
  // Get a list of all Views (Profiles) for the first property
  // of the first Account.
      'accountId': accountId,
      'webPropertyId': propertyId
  .then(null, function(err) {
      // Log any errors.

function handleProfiles(response) {
  // Handles the response from the profiles list method.
  if (response.result.items && response.result.items.length) {
    // Get the first View (Profile) ID.
    var firstProfileId = response.result.items[0].id;

    // Query the Core Reporting API.
  } else {
    console.log('No views (profiles) found for this user.');

function queryCoreReportingApi(profileId) {
  // Query the Core Reporting API for the number sessions for
  // the past seven days.
    'ids': 'ga:' + profileId,
    'start-date': '7daysAgo',
    'end-date': 'today',
    'metrics': 'ga:sessions'
  .then(function(response) {
    var formattedJson = JSON.stringify(response.result, null, 2);
    document.getElementById('query-output').value = formattedJson;
  .then(null, function(err) {
      // Log any errors.

  // Add an event listener to the 'auth-button'.
  document.getElementById('auth-button').addEventListener('click', authorize);

<script src="https://apis.google.com/js/client.js?onload=authorize"></script>


Step 3: Run the sample

After you have enabled the Analytics API, and set up the sample source code the sample is ready to run.

  1. Publish HelloAnalytics.html to your web server and load the page in your browser.
  2. Click the Authorize button, and authorize access to Google Analytics.

When you finish these steps, the sample outputs the name of the authorized user's first Google Analytics view (profile) and the number of sessions for the last seven days.

With the authorized Analytics service object you can now run any of code samples found in the Management API reference docs. For example you could try changing the code to use the accountSummaries.list method.
