Channel Preview

You can preview your channel in the within the Uplynk platform. This allows you to test and verify your channel, including URL parameters, before you actually try it in a production environment.

In conjunction with the developer tools built into the web browser, you can view the actual HTTP requests for playback using your desired URL parameters and the returned manifests.

  1. Go to the channel details page.
