# Recreate the socket, keeping the session

`POST /connections/{phoneNumber}/restart`

Tears down the live socket and spawns a replacement using the stored session, without clearing auth state — no QR, no re-pairing. Recovers a connection that is receiving and passing health checks but whose sends are wedged.

## Path parameters

- `phoneNumber` string, required

## Request body

- object
  - `reason` string — Free-text note recorded in the restart log line

## Response `202`

Restart accepted; reconnecting

## Other responses

- `403` — Forbidden — the API key does not own this connection. Returned when a connection is bound to a different API key.
- `404` — No stored session for this phone number
- `409` — Conflict — in cluster mode, the connection is owned by another live instance (id in the x-baileys-owner header).
- `421` — Misdirected Request — in cluster mode, this instance does not own the connection. The owning instance id is in the x-baileys-owner header; a proxy re-routes the request there. Not returned for the explicit-takeover routes: POST /connections/{phoneNumber}, /import-session and /restart.
