Por exemplo, em uma das maneiras que a especificação OAuth2 pode ser usada (chamada "fluxo de senha"), é necessário enviar um `username` e uma `password` como campos do formulário.

A <abbr title="especificação">spec</abbr> exige que os campos sejam exatamente nomeados como `username` e `password` e sejam enviados como campos de formulário, não JSON.

```JSON
{
    "item": {
        "name": "Foo",
        "description": "The pretender",
        "price": 42.0,
        "tax": 3.2
    },
    "user": {
        "username": "dave",
        "full_name": "Dave Grohl"
    }
}
```

/// note | Примітка

Зверніть увагу, що хоча `item` оголошено, так само як і раніше, тепер він очікується в тілі під ключем  `item`.
