SwitchBot intergration... almost there

so i have got ma switchbot and hub, im trying to add them to HE. i have got so far as creating a Virtual switch, changing the driver to switch bot API. i got the "Token" from Switch bot app on the phone. now i cant get the Device ID. i copy this code into command promt as instructed and it says 'curl' is not reconised.

"curl -H "Authorization:" https://api.switch-bot.com/v1.0/devices"
