# The Published Event Object

When a resource is saved/deleted/signed off, an HTTP/POST request is sent to your target URL.

The target URL should accept a JSON string in the POST body of the request.

The content of the POST will look as follow:

```json theme={null}
{
  "data": {...}, // The object (definition will change per resources)
  "action": "saved", // Actions available: saved, deleted
  "event_id": 1234, // The event id to reference this request
  "event_uuid": "019078c0-4f3a-7abc-9def-0123456789ab", // UUID7 identifier for this event
  "application_id": 12345, // The client id of the oauth2 application
  "resource": "patients", // The resource for this object.
  "resource_url": null // Optional URL to retrieve the resource payload
}
```
