How to display active alarm in clockface?

[SRnoob]

Is there a tutorial how to display my active alarm (i.e. 7:30a.m.) on the clockface? I've been fiddling with the companion app, but i've had no success.

Im trying to make the GET call to the devices as per these instructions here:

https://dev.fitbit.com/build/reference/web-api/devices/#alarms

But i get an error: {"errors":[{"errorType":"system","fieldName":"n/a","message":"Authorization Error: Invalid authorization token type"}],"success":false}

This is my code:

let url = "https://api.fitbit.com/1/user/-/devices.json";
fetch(url).then(function(response) {
return response.text();
}).then(function(text) {
console.log("Got JSON response from server: " + text); });

Am i going in the right direction? Any direction would be appreciated.

You're going to have to get through the oauth stuff. The Settings API oauth button may help, as might this example.
