To run this sample, set apiKey to your application's API key and clientId to
your application's OAuth 2.0 client ID. They can be generated at:
Then, add a JavaScript origin to the client that corresponds to the domain
where you will be running the script. Finally, activate the People API at:
<!DOCTYPE html>
<title>Say hello using the People API</title>
<meta charset='utf-8' />
<p>Say hello using the People API.</p>
<!--Add buttons to initiate auth sequence and sign out-->
<button id="authorize-button" style="display: none;">Authorize</button>
<button id="signout-button" style="display: none;">Sign Out</button>
<div id="content"></div>
