# WhatsApp number verification-required event

`POST whatsapp.number.verification_required` (webhook)

Fired when a regulated number has an out-of-band identity-verification
step (e.g. Onfido). `verificationUrl` is the link to forward to the
number's end user; the order completes once they pass.

## Payload

- object
  - `id` string
  - `event` 'whatsapp.number.verification_required'
  - `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
  - `verificationUrl` string

## Acknowledgement `200`
