# Respond To Message

`POST /api/v1/master/messages/{message_id}/respond`

Answer a question, decide an approval request, or acknowledge an
escalation/report. First decider wins: the status flip is a conditional
update from 'open', so two racing responders can't both decide. Approvals
enqueue an immediate follow-up run that executes the stored action.
