# Close a case

`POST /contact_cases/{id}/close`

Close a case. closed_by_id is derived server-side from the
authenticated caller's own agent identity -- there is no request
body -- so the closing-agent attribution the platform treats as a
hard invariant cannot be forged by supplying an arbitrary agent_id.
Returns the actually-persisted state, including already_closed
semantics reflected via the returned closed_reason / closed_by_type /
closed_by_id fields when the case had already been closed by
someone/something else.
