# list_member_removed

`POST list_member_removed` (webhook)

A contact was removed from a lead list. Same payload as
`list_member_added`, and the same per-row volume caveat.

## Payload

- object: Every outbound event uses this envelope. `data` is the only part that varies by event type.
  - `event` string: Event type. Also sent in the `X-Webhook-Event` header.
  - `timestamp` string, date-time: When the event was delivered — not necessarily when it occurred.
  - `data` object: Event-specific payload.
    - `member_id` string, uuid
    - `list_id` string, uuid
    - `list_name` string
    - `contact_id` string, uuid
    - `contact_name` string, nullable
    - `contact_email` string, nullable
    - `changed_at` string, date-time
  - `webhook_id` string, uuid: Delivery ID. Also sent as `X-Webhook-ID`. Use it to deduplicate retries.
  - `organization_id` string, uuid

## Acknowledgement `200`

Return any 2xx to acknowledge. A non-2xx or a timeout is treated as a failed
delivery and retried with backoff up to your configured `max_retries`.
