Node-red-contrib-smartthings not working

I am trying to get this to work with the NabuCasa URL. I do not think I can put in the port 1880 that Node-RED uses to listen on. I can access the port on my local network with the local URL and I can get to the web hook but that does not let me use it. I need SmartThings to be able to use the webhook and it needs to do this externally.

I hope someone can let me know what the solution is to get this working.

Thanks in advance

I don’t think I need this so I won’t be trying to figure this out. I was trying to get smartthings working in Node-RED in HA. I was over-complicating this and now I realize I just need to use the sensors that I have in HA already.
