### Шаг 3: определите *операцию пути (path operation)*

#### Путь (path)

"Путь" это часть URL, после первого символа `/`, следующего за именем домена.

Для URL:

```
https://example.com/items/foo
```

...путь выглядит так:

```
/items/foo
```

    Термин "path" также часто называется "endpoint" или "route".
