## Eine Anwendung mit Callbacks

Sehen wir uns das alles anhand eines Beispiels an.

Stellen Sie sich vor, Sie entwickeln eine Anwendung, mit der Sie Rechnungen erstellen können.

Diese Rechnungen haben eine `id`, einen optionalen `title`, einen `customer` (Kunde) und ein `total` (Gesamtsumme).

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

con un JSON body de:

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

luego *tu API* procesará la factura, y en algún momento después, enviará un request de callback al `callback_url` (la *API externa*):

```

 * retry policies, and contextual information.
 *
 * This exception consolidates the various SMB exception types and provides:
 * - Standardized error codes
 * - Automatic retry policies
 * - Rich contextual information
 * - Error categorization
 * - Performance metrics
 */
public class SmbOperationException extends CIFSException implements Serializable {

    private static final long serialVersionUID = 1L;

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

⏮️ 🎻 💪:

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

⤴️ *👆 🛠️* 🔜 🛠️ 🧾, & ☝ ⏪, 📨 ⏲ 📨 `callback_url` ( *🔢 🛠️*):

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

⏮️ 🎻 💪 ⚗ 🕳 💖:

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

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://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 uma solicitação de callback para o `callback_url` (a *API externa*):
