1. Start from the official Python base image.

2. Set the current working directory to `/code`.

    This is where we'll put the `requirements.txt` file and the `app` directory.

3. Copy the file with the requirements to the `/code` directory.

    Copy **only** the file with the requirements first, not the rest of the code.

При создании API «путь» — это основной способ разделения «задач» и «ресурсов».

#### Операция (operation) { #operation }

«Операция» здесь — это один из HTTP-«методов».

Один из:

* `POST`
* `GET`
* `PUT`
* `DELETE`

...и более экзотические:

* `OPTIONS`
* `HEAD`
* `PATCH`
* `TRACE`

В протоколе HTTP можно обращаться к каждому пути, используя один (или несколько) из этих «методов».

## FastAPI と OpenAPI による Webhook のドキュメント化 { #documenting-webhooks-with-fastapi-and-openapi }

**FastAPI** と OpenAPI を使うと、Webhook の名前、アプリが送信できる HTTP の操作（例: `POST`, `PUT` など）、アプリが送るリクエストの**ボディ**を定義できます。

これにより、ユーザーがあなたの **Webhook** リクエストを受け取るための**API を実装**するのが大幅に簡単になります。場合によっては、ユーザーが自分たちの API コードを自動生成できるかもしれません。

/// info | 情報

Webhook は OpenAPI 3.1.0 以上で利用可能で、FastAPI `0.99.0` 以上が対応しています。
