Streaming Destinations
The destination table lists the external endpoints configured for the simulcast stream.

Treat stream keys as sensitive credentials. Do not publish or share them with anyone who should not be able to stream to the configured destination.
One simulcast instance can display multiple destination rows when it was configured to stream to more than one endpoint.
Fields, destinations, webhook information, and credentials depend on the RTMP configuration, stream state, and data available for the selected meeting.
