With your Uber application in place, visit the Uber > OAuth bundle. Starting with the InitializeOAuth Choreo, use these Choreos to grant your application access to an Uber account. This short video demonstrates how to use our OAuth Choreos, and it's a good idea to take a break and watch it now before you dive into this step. This process will return an Access Token which can be used to authenticate with Uber. When an Access Token expires, you can run the Uber > OAuth > RefreshToken choreo providing the Client ID, Client Secret, and Refresh Token (also returned during the OAuth process) to retrieve a new Access Token.
Note: if your application only needs to use Choreos within the Projects and Estimates bundle, you'll just need to authenticate using your ServerToken. For Choreos within the User bundle, you are required to authenticate using OAuth credentials.
