A utility endpoint that will push a command to the camera to play an audible in-cab alert sound immediately upon receipt of the request.Due to the asynchronous nature of this API, there is an expected network delay between submiting the request and the server sending the request to the camera. To help with this, a future date-time value can be passed into the expires parameter to set an expiration for the prompt so that if the request is received after this time, it will be ignored. This will prevent any potential confusion of the driver by playing an alert too long after the initial trigger event.
