Are you using PHP? If so, this guide should have you covered: https://github.com/ryanjarvinen/eventbrite.php/blob/master/OAUTH2-README.md

By default, PHP's $_SESSION store will be used to save each user's access_token. You'll need PHP session support to be enabled in order to get the basic demo working: https://github.com/ryanjarvinen/eventbrite.php/blob/master/OAUTH2-README.md#2a-using-phps-built-in-_session-storage-optional

PHP's default $_SESSION storage definitely has a few trade offs. If it is not your preferred data storage system, you can provide your own data-management callbacks, allowing you to store the access_token in a cookie, in your database, or in any other location that works well with your system architecture. More information is available here: https://github.com/ryanjarvinen/eventbrite.php/blob/master/OAUTH2-README.md#3-define-data-management-callbacks

Here is a basic implementation example, which takes advantage of the default $_SESSION store: https://github.com/ryanjarvinen/eventbrite.php/blob/master/examples/oauth2-login-example.php
