# Register Instant Match Call

`POST /video/register-instant-match`

Register an instant match call for proper end call notifications

🔒 Had zero auth dependency — anyone could overwrite ANY call_id's active-
call registry entry (caller/callee identities, room name, and — since this
merges with `existing_data` — could also be used to probe/tamper with an
in-flight call's token-economy fields). Now requires the caller to be one
of the two parties they're naming.
