Digi cloud kit and FreeBoard.io

Hi, i use Digi cloud kit and i want to upload sensor data from this platform (https://xbeegateway.herokuapp.com/#/login) to the FreeBoard.io. I’ve noticed that in digi remote manager- event log i receive messages with url address (https://xbeegateway.herokuapp.com/api/monitor) from the Digi cloud kit. So, i try to use this address in Freeboard (with JSON data source), in order to obtain sensor data, directly from the https://xbeegateway.herokuapp.com/api/monitor, but i don’t receive no data. Is my idea possible?
