Hi there,
This is not change, there are different methods how to send commands to device via API. In this question RMS API - keep getting "FORBIDDEN" / basic API setup help needed - #7 by Arturas we have a guide how to utilize API commands via postman, and that is the recommended method. Follow the instructions in the guide, and you should be able to successfully send API request to the device. I would recommend testing the above method, and please advise whether you unable to utilize this, or you don’t get expected values, as this method has been tested working.
Regards,
Arturas
