# WhatsApp number released event

`POST whatsapp.number.released` (webhook)

Fired when a number is released and is no longer usable (by the user, a
billing cleanup, or an admin). Terminal. `reason` carries the cause
(e.g. `user_requested`, `cleanup_suspended`).

## Payload

- object
  - `id` string
  - `event` 'whatsapp.number.released'
  - `timestamp` string, date-time — UTC time at which Zernio generated this event (set once when the event payload is built, before delivery is queued). Retries and redeliveries keep the original value, so it reflects the event, not the delivery attempt.
  - `number` object
    - `id` string
    - `phoneNumber` string
    - `country` string
    - `profileId` string
  - `reason` string, nullable

## Acknowledgement `200`
