# End Instant Match Call Session

`POST /instant-match/sessions/{match_session_id}/end`

End an instant match call session and update the corresponding call session.

🔒 Had no participant check — anyone who knew a match_session_id (a
URL-shaped string, not a secret) could force-end another pair's call,
including its billing-relevant duration/status side effects.

Also had no `except HTTPException: raise` before its catch-all — unlike
every other endpoint in this file — so the 403 this fix raises would have
been swallowed and reported back as a generic 500.

## Path parameters

- `match_session_id` string, required

## Headers

- `authorization` string, nullable

## Response `200`

Successful Response

- unknown

## Other responses
