# 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`
even on coexistence numbers where the inbound referral omits it (this
webhook is the only surface that delivers it there); the clid is also
written 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`
