# Revoke a sandbox session

`DELETE /v1/whatsapp/sandbox/sessions/{sessionId}`

Hard-deletes the session. The user loses the ability to send to that
phone via the sandbox until they re-activate it. Existing conversations
and messages already exchanged with that phone are untouched —
revocation only blocks FUTURE sends.

Sessions belonging to other users cannot be revoked; the response is
the same 400 as "session not found" so existence isn't leaked.

## Path parameters

- `sessionId` string, required

## Response `200`

Session revoked

- object
  - `success` boolean

## Other responses

- `400` — Invalid or unknown session id
- `401` — Unauthorized
- `403` — Inbox addon required
