Dans ce cas, c’est la `str` :

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

Ainsi, si l’utilisateur de votre API (la personne développeuse externe) envoie une requête à *votre API* vers :

```
https://yourapi.com/invoices/?callback_url=https://www.external.org/events
```

avec un corps JSON :

```JSON
{
    "id": "2expen51ve",

本例中是 `str`：

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

因此，如果您的 API 用户（外部开发者）发送请求到您的 API：

```
https://yourapi.com/invoices/?callback_url=https://www.external.org/events
```

使用如下 JSON 请求体：

```JSON
{
    "id": "2expen51ve",
    "customer": "Mr. Richie Rich",
