This sample configuration uses a `webhook` at http://127.0.0.1:8010/webhook to post the alerts.

Existem situações onde você deseja informar os **usuários** da sua API que a sua aplicação pode chamar a aplicação *deles* (enviando uma requisição) com alguns dados, normalmente para **notificar** algum tipo de **evento**.

Isso significa que no lugar do processo normal de seus usuários enviarem requisições para a sua API, é a **sua API** (ou sua aplicação) que poderia **enviar requisições para o sistema deles** (para a API deles, a aplicação deles).

            if (!listeners.isEmpty()) {
                Event event = new DefaultEvent(session, ee, eventType);
                for (Listener listener : listeners) {
                    listener.onEvent(event);
                }
            }
        }
    }

with a JSON body of:

```JSON
{
    "id": "2expen51ve",
    "customer": "Mr. Richie Rich",
    "total": "9999"
}
```

then *your API* will process the invoice, and at some point later, send a callback request to the `callback_url` (the *external API*):

```
https://www.external.org/events/invoices/2expen51ve
```

https://yourapi.com/invoices/?callback_url=https://www.external.org/events
```

com um corpo JSON de:

```JSON
{
    "id": "2expen51ve",
    "customer": "Mr. Richie Rich",
    "total": "9999"
}
```

então *sua API* processará a fatura e, em algum momento posterior, enviará um request de callback para o `callback_url` (a *API externa*):

```
https://www.external.org/events/invoices/2expen51ve
```
