В нашем случае это `str`:

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

Итак, если пользователь вашего API (внешний разработчик) отправляет HTTP-запрос вашему API по адресу:

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

* Vous devriez maintenant avoir une structure de répertoire telle que :

```
.
├── app
│   └── main.py
└── Dockerfile
```

## Construire l'image Docker

* Allez dans le répertoire du projet (dans lequel se trouve votre `Dockerfile`, contenant votre répertoire `app`).
* Construisez votre image FastAPI :

<div class="termy">

```console
$ docker build -t myimage .

---> 100%
```

</div>
