# Common Envelope

> Shared webhook envelope fields for all Spark360 events.

All Spark360 webhook events use the same top-level envelope for consistent parsing and idempotency.

```json theme={null}
{
  "event": "lead.enriched",
  "event_id": "uuid-v4",
  "timestamp": "2026-04-06T14:22:00Z",
  "organization_id": "b8ff2073-228d-4f0f-b5db-28b49cf4069e",
  "data": {}
}
```

* `event_id`: unique per delivery attempt; use for deduplication
* `timestamp`: ISO 8601 UTC
* `organization_id`: Spark360 organization UUID
