唯一の新しい点は、*path operation デコレータ*の引数として `callbacks=invoices_callback_router.routes` を渡すことです。これが何かは次で見ます。

## コールバックのドキュメント化 { #documenting-the-callback }

実際のコールバックのコードは、あなた自身の API アプリに大きく依存します。

そしてアプリごとに大きく異なるでしょう。

それは次のように 1、2 行のコードかもしれません:

```Python
callback_url = "https://example.com/api/v1/invoices/events/"
httpx.post(callback_url, json={"description": "Invoice paid", "paid": True})
```

			dec.Reset(nil)
			s2DecPool.Put(dec)
			readMsgpReaderPoolPut(mr)
		},
		creator: func() error {
			v, err := mr.ReadByte()
			if err != nil {
				return err
			}
			switch v {
			case 1, 2:
			default:
				return fmt.Errorf("metacacheReader: Unknown version: %d", v)
			}
			return nil
		},
	}
}

func (r *metacacheReader) checkInit() {
	if r.creator == nil || r.err != nil {

## Response Model encoding parametreleri { #response-model-encoding-parameters }

Response model’inizde şu şekilde default değerler olabilir:

{* ../../docs_src/response_model/tutorial004_py310.py hl[9,11:12] *}

* `description: Union[str, None] = None` (veya Python 3.10’da `str | None = None`) için default `None`’dır.
* `tax: float = 10.5` için default `10.5`’tir.
* `tags: List[str] = []` için default, boş bir list’tir: `[]`.

## Parameter für die Enkodierung des Responsemodells { #response-model-encoding-parameters }

Ihr Responsemodell könnte Defaultwerte haben, wie:

{* ../../docs_src/response_model/tutorial004_py310.py hl[9,11:12] *}

* `description: Union[str, None] = None` (oder `str | None = None` in Python 3.10) hat einen Defaultwert `None`.
* `tax: float = 10.5` hat einen Defaultwert `10.5`.
