ここでの「オペレーション」とは、HTTPの「メソッド」の1つを指します。

以下のようなものの1つ:

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

...さらによりエキゾチックなもの:

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

HTTPプロトコルでは、これらの「メソッド」の1つ（または複数）を使用して各パスにアクセスできます。

---

APIを構築するときは、通常、これらの特定のHTTPメソッドを使用して特定のアクションを実行します。

通常は次を使用します:

* `POST`: データの作成
* `GET`: データの読み取り
* `PUT`: データの更新
* `DELETE`: データの削除
