Por ejemplo, supongamos que quieres tener una *path operation* que permita actualizar elementos, y devuelva códigos de estado HTTP de 200 "OK" cuando sea exitoso.

Pero también quieres que acepte nuevos elementos. Y cuando los elementos no existían antes, los crea y devuelve un código de estado HTTP de 201 "Created".

///

/// check | Revisa

OpenAPI especifica que cada *path operation* requiere una descripción de response.

Entonces, si no proporcionas una, **FastAPI** generará automáticamente una de "Response exitoso".

## Deprecar una *path operation* { #deprecate-a-path-operation }

En breve:

* `100 - 199` son para "Información". Rara vez los usas directamente. Los responses con estos códigos de estado no pueden tener un body.
* **`200 - 299`** son para responses "Exitosos". Estos son los que usarías más.
    * `200` es el código de estado por defecto, lo que significa que todo estaba "OK".
    * Otro ejemplo sería `201`, "Created". Comúnmente se usa después de crear un nuevo registro en la base de datos.
