# Open Instant Match Room

`POST /instant-match/sessions/{session_id}/room`

The private group room this match opens. Idempotent: either person may
ask, and the second one gets the room the first one made.

Who may be here comes from the MATCH SESSION and nothing else. The caller
is the token; the other person is whoever the match says they are. Nothing
is read out of the request body, so a body cannot name a stranger.
