# Show the Authentication UI

Once you’ve got your API Client ID & Secret and you’ve successfully generated a token, it’s time to render Rollout Link in your application. Rollout Link is the authentication UI that enables your users to authenticate with their CRM/TMS of choice and once that credential is stored, you can make API requests to read and write data to their CRM/TMS.
