You can type messages in the input box, and send them:

You can send (and receive) many messages:

`PUT` se usa para recibir datos que deben reemplazar los datos existentes.

### Advertencia sobre el reemplazo { #warning-about-replacing }

Esto significa que si quieres actualizar el ítem `bar` usando `PUT` con un body que contenga:
