Swagger UI lo manejará detrás de escena para ti, pero necesita este auxiliar de "redirección".

### Crea una *path operation* para probarlo { #create-a-path-operation-to-test-it }

Ahora, para poder probar que todo funciona, crea una *path operation*:

### Pruébalo { #test-it }

///

### Crea un `APIRouter` de callback { #create-a-callback-apirouter }

Primero crea un nuevo `APIRouter` que contendrá uno o más callbacks.

### Crea la *path operation* del callback { #create-the-callback-path-operation }

Swagger UI lidará com isso nos bastidores para você, mas ele precisa desse auxiliar de "redirecionamento".
