Hello @Milan Perovic**,**
welcome to this moderated Azure community forum.
Azure IoT Central is a Software-as-a-Service solution based on the well-known Azure IoT Platform-as-a-Service resources.
For example, it has an IoT Hub and a Device Provisioning Services built in but these are not fully disclosed, expect for certain endpoints.
If you want to send data, as a device, to Azure IoT Central, you need to create the device first (via de DPS interface). Only then you can start sending data.
By the way, this is the recommended way of setting up communication in case the PaaS services are used. Only having an IoT Hub is a configuration risk and limits flexibility.
So, it's not recommended communication with the IoT Central IoT hub directly. That is why this interface is not documented for IoT Central.
