Summary

Send a fan-out message to all subscribers on a broadcast channel in Backchannel.

Inputs

  • Channel (required) — The name or ID of the broadcast channel to which the message will be sent.
  • Content (required) — The message payload to broadcast; can be plain text or a JSON string.
  • Actor Label — A short label identifying this workflow as the producer of the broadcast message; defaults to 'n8n'.

Output shape

a list of JSON objects each representing the result of the broadcast message including the channel ID and message metadata

Each output item corresponds to an input item processed, containing the channel identifier and the server's response to the broadcast POST. The operation ensures the broadcast channel exists (creating it if necessary) before sending the message. Errors result in failures unless 'Continue On Fail' is enabled, in which case error messages are returned instead.
