+#### Google Access Token (Android only, iOS Coming soon)
+Upon successful authentication, Google creates an access token that can be obtained from the login method's result object. This access token can then be used for Google API:
+
+```js
+"providers": [
+         {
+             "id": "google.com",
+             "token": "<Google Access Token>"
+         }
+     ]
+```
+
 #### iOS
 If you didn't choose this feature during installation you can open the `Podfile` in the plugin's `platforms/ios` folder and uncomment the `GoogleSignIn` line.
