# WhatsApp automatic event detected

`POST whatsapp.automatic_event` (webhook)

Fired when Meta's automatic event identification (opt-in during
Embedded Signup; not available for EU/UK/JP businesses) detects a
lead or purchase in a Click-to-WhatsApp conversation. Branch on
`eventName` (`LeadSubmitted` | `Purchase`). Carries the `ctwa_clid`.
Meta omits that clid on a minority of referrals on any number
(coexistence or not, most often WhatsApp Status placements); when it
does, this event can supply it and Zernio writes it back onto the
conversation, so POST /v1/whatsapp/conversions becomes usable for the
thread.

## Payload

- object
  - `id` string
  - `event` 'whatsapp.automatic_event'
  - `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.
  - `accountId` string — SocialAccount id of the WhatsApp number whose conversation was flagged.
  - `conversationId` string — Zernio conversation id, when the thread could be resolved.
  - `platformMessageId` string — The wamid of the message Meta's analysis flagged.
  - `eventName` string — Meta-detected event: `LeadSubmitted` | `Purchase`.
  - `ctwaClid` string — Meta's CTWA click id, the Conversions API match key.
  - `customData` object — Purchase events may carry the detected amount.
    - `currency` string
    - `value` number
  - `detectedAt` string, date-time

## Acknowledgement `200`
