Nesse caso, é a `str`:

```Python
"{$callback_url}/invoices/{$request.body.id}"
```

Então, se o usuário da sua API (o desenvolvedor externo) enviar um request para *sua API* para:

```
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"
}
```

        this.id(spec.asConfigurationId(model))

    return user_id


# Модель Pydantic
class User(BaseModel):
    id: int
    name: str

```

Это можно использовать так:

```Python
my_user: User = User(id=3, name="John Doe", joined="2018-07-19")

second_user_data = {
    "id": 4,
    "name": "Mary",
    "joined": "2018-11-30",
}

my_second_user: User = User(**second_user_data)
```

 *  Fix: Handle either `TLS_` or `SSL_` prefixes for cipher suite names. This is necessary for
    IBM JVMs that use the `SSL_` prefix exclusively.
 *  Fix: Reject HTTP/2 data frames if the stream ID is 0.
 *  New: Upgrade to Okio 1.12.0.
