# WebhookEnvelope

> A schema in the One API reference. Source: https://hub.ozow.com/api-reference/one-api/schemas/webhook-envelope/

Every delivery has this shape. `data` is what the subscription's message type decides.

## Fields

- `type` (string, required) - The event type the subscription was created for.
- `timestamp` (string, date-time, required) - When the event was raised.
- `data` (any of, required) - What the subscription's message type decides. A `thin` subscription receives `WebhookEventData`, which is every event's default and the only form the subscription events support. A `full` subscription to `transaction.complete` receives `TransactionCompleteFullData`, and to `refund.complete`, `RefundCompleteFullData`. A `full` subscription to any of the subscription events receives nothing at all.
  - Option 1: `WebhookEventData`
  - Option 2: `TransactionCompleteFullData`
  - Option 3: `RefundCompleteFullData`
