The TelstraDev Track and Monitor API is specifically designed to pull the location and environmental insights from the Telstra Track and Monitor Device range, which can be purchased through Telstra or a Telstra partner.
This API is not valid for BYO devices from third parties. If you have your own IoT device that you wish to draw insights from via API, unfortunately this API is not suitable.
We'd love to hear your use cases and suggestions on how we can expand our IoT offering for developers, please let us know! https://dev.telstra.com/content/how-can-we-do-better
