API Access Now Available
Start and stop streams, toggle captions, and change languages from Companion, ProPresenter, or a simple HTTP request. Every LiveSunday plan now includes API keys.

You can now drive LiveSunday from the tools you already use in the booth.
The API can start and stop a stream, check whether a session is running, clear or hide captions, and change transcription or translation languages. A dashboard admin still needs to be connected with audio ready before a start request will succeed.
Bitfocus Companion and ProPresenter can call the same endpoints, so a button press can stand in for clicking Start on the Stream page.
Read the full reference, including authentication and language codes, in the API docs. Explore and try requests in the interactive specification.
