### Paso 3: crea una *path operation* { #step-3-create-a-path-operation }

#### Path { #path }

"Path" aquí se refiere a la última parte de la URL empezando desde la primera `/`.

Así que, en una URL como:

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

...el path sería:

```
/items/foo
```

/// info | Información

Un "path" también es comúnmente llamado "endpoint" o "ruta".

### O que é "Montagem" { #what-is-mounting }

"Montagem" significa adicionar uma aplicação completamente "independente" em um path específico, que então cuida de lidar com todos os sub-paths.

Isso é diferente de usar um `APIRouter`, pois uma aplicação montada é completamente independente. A OpenAPI e a documentação da sua aplicação principal não incluirão nada da aplicação montada, etc.
