# Register a Device for Notifications

> Save a device's push token so a user gets notifications on it.

A user can have several devices — register each one and they all receive
notifications. Sending the same token again is safe and simply refreshes it.

        Standard response wrapper for single-object responses and errors.

        Generic over the payload type. A route that declares
        ``CommonResponse[SomeModel]`` gets the real ``data`` schema rendered in
        OpenAPI/Swagger; a bare ``CommonResponse`` leaves ``data`` untyped.
