# Retornando uma Resposta Diretamente

Quando você cria uma *operação de rota* no **FastAPI** você pode retornar qualquer dado nela: um dicionário (`dict`), uma lista (`list`), um modelo do Pydantic ou do seu banco de dados, etc.

Por padrão, o **FastAPI** irá converter automaticamente o valor do retorno para JSON utilizando o `jsonable_encoder` explicado em [JSON Compatible Encoder](../tutorial/encoder.md){.internal-link target=_blank}.

	Queue Queue

func (err ErrDuplicateQueueConfiguration) Error() string {
	var message string
	if data, xerr := xml.Marshal(err.Queue); xerr != nil {
		message = fmt.Sprintf("%+v", err.Queue)
	} else {
		message = string(data)
	}

	return fmt.Sprintf("duplicate queue configuration %v", message)
}

// ErrUnknownRegion - unknown region error.

	flag.StringVar(&clientSecret, "csec", "", "Client secret")
}

	data := url.Values{}
	data.Set("grant_type", "client_credentials")

	if err != nil {
		return nil, err
	}
	req.Header.Set("Content-Type", "application/x-www-form-urlencoded")

Keep in mind that if you return a response directly instead of using the `Response` parameter, FastAPI will return it directly.

So, you will have to make sure your data is of the correct type. E.g. it is compatible with JSON, if you are returning a `JSONResponse`.

And also that you are not sending any data that should have been filtered by a `response_model`.
