I am trying to incorporate the UUID of the button into a post request to a web API.

This is what I have right now for application/json, but it's a bad request as to how to reference the UUID. Does anyone have ideas about how to access UUID?

{"ClickType": "1", "button_id": uuid}

I looked at this documentation: https://github.com/50ButtonsEach/fliclib-linux-hci/blob/master/ProtocolDocumentation.md#evtgetbuttoninforesponse

But still doesn't help much. If anyone can give any idea how to pass on uuid in post request, please help!!!
