## 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).

Der Benutzer Ihrer API (ein externer Entwickler) erstellt mit einem POST-Request eine Rechnung in Ihrer API.

Dann wird Ihre API (beispielsweise):

//   prefix: PREFIX
//   encryption:
//     type: sse-s3 # valid values are sse-s3 and sse-kms
//     key: <new-kms-key> # valid only for sse-kms
//     context: <new-kms-key-context> # valid only for sse-kms
// # optional flags based filtering criteria
// # for all objects
// flags:
//   filter:
//     newerThan: "7d" # match objects newer than this value (e.g. 7d10h31s)

Por ejemplo, el modelo anterior declara un “`object`” JSON (o `dict` en Python) como:

```JSON
{
    "name": "Foo",
    "description": "An optional description",
    "price": 45.2,
    "tax": 3.5
}
```

...dado que `description` y `tax` son opcionales (con un valor por defecto de `None`), este “`object`” JSON también sería válido:

```JSON
{
