# Apply a heartbeat action

Say yes to one planned action and let it happen — today that means sending the follow-up it drafted on its conversation. 409 when the action is no longer in the planned state, or is a kind with nothing to apply. If the thread's contact changed between drafting and approval the approval becomes a REFUSAL carrying that reason rather than a message to the wrong person. Admin only.

Access class: `workspace:admin`.
