# Events, Deliveries, and Attempts

# Events, Deliveries, and Attempts

Praeto Dispatcher separates webhook delivery into three records.

## Event

An event is the publisher-side object accepted by Praeto.

```json theme={null}
{
  "event_type": "invoice.created",
  "payload": {
    "invoice_id": "inv_001"
  }
}
```

The event stores `event_id`, `tenant_id`, `event_type`, `payload`, `idempotency_key`, `payload_hash`, and `created_at`.

## Delivery

A delivery is the planned delivery of one event to one endpoint. One event can create many deliveries if multiple endpoints subscribe to the event type.

Delivery statuses include `pending`, `delivered`, `failed`, and `dead_lettered`.

## Attempt

A delivery attempt records each outbound HTTP try, including status code, response body, and creation timestamp.
