# Heartbeat Call Session

`POST /call/sessions/{call_session_id}/heartbeat`

Update heartbeat for an active call session to prevent it from being cleaned up

🔒 Had no auth dependency — anyone who knew/guessed a call_session_id could
keep an arbitrary call "alive" indefinitely, defeating orphan cleanup.
Requires the caller to be an authenticated participant of the session.

## Path parameters

- `call_session_id` string, required

## Headers

- `authorization` string, nullable

## Response `200`

Successful Response

## Changes

- **2026-09-02** `45cbba31aa7d` — 1 info
  - added the new optional `header` request parameter `authorization`
