# Webhook message format

Webhook messages are structured in a JSON format, which includes several key properties that provide important information about the event. The `resource` property contains an object that matches the format of the response object for the corresponding API call.

Here is a breakdown of the main properties in a webhook message:

| Field           | Description                                                                                                                                     |
| --------------- | ----------------------------------------------------------------------------------------------------------------------------------------------- |
| `id`            | A unique identifier for the webhook event.                                                                                                      |
| `create_time`   | The timestamp when the event was created.                                                                                                       |
| `resource_type` | The type of resource associated with the event (e.g., authorization, payment).                                                                  |
| `event_version` | The version of the event schema.                                                                                                                |
| `event_type`    | The specific type of event that occurred (e.g., PAYMENT.AUTHORIZATION.CREATED).                                                                 |
| `summary`       | A brief description of the event.                                                                                                               |
| `resource`      | An object containing details about the resource involved in the event. See the coresponding API documentation for the structure of this object. |
