# post.external.deleted

A tracked native post was removed from the platform.

### Payload notes

`post.deletedAt` is the detection time.

### Detection limits

Coverage is bounded to the most recent posts the platform listing returns, so very old deletions may go undetected.

### When it does not fire

Detection diffs against posts a prior sync already indexed. An account with no indexed post never emits it.




**Payload for `post.external.deleted`:**

- **id** (required) `string`: Stable webhook event ID: the dedupe key, also sent as the X-Zernio-Event-Id header and identical on every retry and redelivery. It identifies the event only, never an account or other resource.
- **profiles**: `WebhookProfiles` - See schema definition
- **test** `boolean`: Always true when present: only a sample sent by POST /v1/webhooks/test with an event carries it. Real deliveries never do.
- **event** (required) `string`: No description - one of: post.external.created, post.external.updated, post.external.deleted
- **post** (required): `ExternalPostWebhookPost` - See schema definition
- **account** (required) `object`: 
  - **id** (required) `string`: No description
  - **accountId** `string`: Account ID (same as id); canonical field for account filtering.
  - **platform** (required) `string`: No description
  - **username** (required) `string`: No description
- **timestamp** (required) `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.
