Proper method of getting a server auth access token for a client to use with google analytics
[Here][1] is an example of how to set up server side auth. The above code creates a new token when anyone visits the site. You can see the endpoint that gets that access token [here][2].
Below are the general steps to get to a working version:
Step 1: Create a service account and download the JSON key
Step 2: Add the service account as a user in Google Analytics
Step 3: Use the JSON key data to request an access token
# service-account.py
import json
from oauth2client.client import SignedJwtAssertionCredentials
# The scope for the OAuth2 request.
SCOPE = 'https://www.googleapis.com/auth/analytics.readonly'
# The location of the key file with the key data.
KEY_FILEPATH = 'path/to/json-key.json'
# Load the key file's private data.
with open(KEY_FILEPATH) as key_file:
_key_data = json.load(key_file)
# Construct a credentials objects from the key data and OAuth2 scope.
_credentials = SignedJwtAssertionCredentials(
_key_data['client_email'], _key_data['private_key'], SCOPE)
# Defines a method to get an access token from the credentials object.
# The access token is automatically refreshed if it has expired.
def get_access_token():
return _credentials.get_access_token().access_token
Back to the client side:
Step 4: Load the Embed API library.
<script>
(function(w,d,s,g,js,fs){
g=w.gapi||(w.gapi={});g.analytics={q:[],ready:function(f){this.q.push(f);}};
js=d.createElement(s);fs=d.getElementsByTagName(s)[0];
js.src='https://apis.google.com/js/platform.js';
fs.parentNode.insertBefore(js,fs);js.onload=function(){g.load('analytics');};
}(window,document,'script'));
</script>
Step 5: Add HTML containers to host the dashboard components.
<div id="chart-1-container"></div>
<div id="chart-2-container"></div>
Step 6: Write the dashboard code.
Use the access token obtained in step 3 to authorize the Embed API.
gapi.analytics.ready(function() { /** * Authorize the user with an access token obtained server side. */ gapi.analytics.auth.authorize({ 'serverAuth': { 'access_token': '{{ ACCESS_TOKEN_FROM_SERVICE_ACCOUNT }}' } }); ... The additional work of creating an endpoint which returns the token depends on your back end implementation but the source code of how the demo does it can be found [here][2].
