How can I access the device REST APIs using Postman?
The documentation is shown here:
First, which authentication method do I use? I am assuming I have to use my Ubuntu One account and the key associated with it, right?
Also, I am assuming I can access the device on Port 80 right? So it would be http://<ip_address>/v2/system-info as the GET request.
Can someone verify this?
No, you can only access it from localhost via the socket … to do any remote management you need to create an agent snap that utilizes the snapd-control interface and then forwards the requests/replies to the network…

(curl should also work via http://localhost … and the socket option)
@ogra a few months ago I remember standing up the IoT Management web dashboard provided by Canonical.
I remember installing a “iot-agent” Snap, this is what it looked like:
Do you think if I launched this “iot-agent” Snap again, it would allow me to call the APIs using IP address, followed by “/v2/”?
The iot-agent snap communicates via MQTT with the server, I don’t think there is an open web port… but you could grab the source and adapt it I guess …
See:
There are also links to the source of the various involved services as well as the server code linked from the README…
