那麼「你的 API」會處理這張發票，並在稍後某個時點，向 `callback_url`（也就是「外部 API」）送出回呼請求：

```
https://www.external.org/events/invoices/2expen51ve
```

其 JSON body 大致包含：

```JSON
{
    "description": "Payment celebration",
    "paid": true
}
```

而它會預期該「外部 API」回傳的 JSON body 例如：

```JSON
{
    "ok": true
}
```

/// tip

```
https://www.external.org/events/invoices/2expen51ve
```

with a JSON body containing something like:

```JSON
{
    "description": "Payment celebration",
    "paid": true
}
```

and it would expect a response from that *external API* with a JSON body like:

```JSON
{
    "ok": true
}
```

/// tip

```

然后，您的 API 就会处理发票，并在某个点之后，发送回调请求至 `callback_url`（外部 API）：

```
https://www.external.org/events/invoices/2expen51ve
```

JSON 请求体包含如下内容：

```JSON
{
    "description": "Payment celebration",
    "paid": true
}
```

它会预期*外部 API* 的响应包含如下 JSON 请求体：

```JSON
{
    "ok": true
}
```

/// tip | 提示

その後 *あなたの API* は請求書を処理し、のちほど `callback_url`（*外部 API*）へコールバックのリクエストを送ります:

```
https://www.external.org/events/invoices/2expen51ve
```

JSON ボディは次のような内容です:

```JSON
{
    "description": "Payment celebration",
    "paid": true
}
```

そして *外部 API* からは次のような JSON ボディのレスポンスを期待します:

```JSON
{
    "ok": true
}
```

/// tip | 豆知識

```
https://www.external.org/events/invoices/2expen51ve
```

ve JSON body yaklaşık şöyle bir şey içerecek:

```JSON
{
    "description": "Payment celebration",
    "paid": true
}
```

ve o *external API*'den şu gibi bir JSON body içeren response bekleyecek:

```JSON
{
    "ok": true
}
```

/// tip | İpucu

```
https://www.external.org/events/invoices/2expen51ve
```

con un JSON body que contiene algo como:

```JSON
{
    "description": "Payment celebration",
    "paid": true
}
```

y esperaría un response de esa *API externa* con un JSON body como:

```JSON
{
    "ok": true
}
```

/// tip | Consejo

```
https://www.external.org/events/invoices/2expen51ve
```

mit einem JSON-Body, der etwa Folgendes enthält:

```JSON
{
    "description": "Payment celebration",
    "paid": true
}
```

und sie würde eine Response von dieser *externen API* mit einem JSON-Body wie dem folgenden erwarten:

```JSON
{
    "ok": true
}
```

/// tip | Tipp

```
https://www.external.org/events/invoices/2expen51ve
```

avec un corps JSON contenant quelque chose comme :

```JSON
{
    "description": "Payment celebration",
    "paid": true
}
```

et elle s’attendra à une réponse de cette *API externe* avec un corps JSON comme :

```JSON
{
    "ok": true
}
```

/// tip | Astuce

```
https://www.external.org/events/invoices/2expen51ve
```

com um corpo JSON contendo algo como:

```JSON
{
    "description": "Payment celebration",
    "paid": true
}
```

e esperaria uma resposta daquela *API externa* com um corpo JSON como:

```JSON
{
    "ok": true
}
```

/// tip | Dica

```
https://www.external.org/events/invoices/2expen51ve
```

그리고 다음과 같은 JSON body를 포함할 것입니다:

```JSON
{
    "description": "Payment celebration",
    "paid": true
}
```

또한 그 *external API*로부터 다음과 같은 JSON body 응답을 기대합니다:

```JSON
{
    "ok": true
}
```
