# Subscription collection succeeded

Raised when an individual collection succeeds. Beta, subject to change.

Delivered by Svix, with `svix-id`, `svix-timestamp` and `svix-signature` headers. Verify the signature with the webhook's secret before acting on the contents.

## Authentication

Ozow sends no credential with this call, so this check is the only thing standing between a real delivery and a stranger’s. Verify the delivery signature before acting on the contents: your notification URL is public, and anyone can post to it.

## Payload

**application/json**

- `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`
