Enterprise Feature - SMS is only available on Enterprise plans.
status: "human_handoff_ended" webhook fires.
If the pathway is still sitting on the Transfer to Human node, pass
node_id so the agent continues somewhere useful. Otherwise the next inbound message re-enters that node and hands the thread off again.Headers
Path Parameters
Body Parameters
A fixed message to send from the agent as it takes the thread back. Cannot be combined with
generate_reply.Have the agent generate and send its next turn immediately from the current (or
node_id) node, rather than waiting for the user to text.Response
