Apple Shortcuts API URL Dynamic Reaction

I have recently started using apple shortcuts to connect to a server to control a remote device.

This remote device replies using JSON and depending on the request, it replies with a different status message.

I would like to be able to read the reply in the shortcut and change the icon and/or the colour of the shortcut on the home screen depending on the reply.

This could be used for locking a door where the reply indicates if the door is locked/unlocked by way of a closed/open padlock or by changing the background colour of the shortcut.
