RESTful Web API Design with Node.js (Video 9)

This video tutorial explains how to exchange a temporary credential for an access token, use it to retrieve user information, and log the user into an application. It covers modifying the authenticator using the OAuth module, handling callbacks, and verifying user identity through Twitter's API. The video concludes with a summary and a preview of exploring Twitter's REST API in the next session.
