Need help setting up webhook in node red/IFTTT

I am trying to set up a webhook to receive a command from IFTTT that will be passed into node red either by the webhook, http request, or IFTTT node, but I can’t figure out how to set it up. I have my webhooks code from IFTTT but I don’t know what to do with it, and I have the webhooks set up properly if I were to receive them and do a home assistant automation, but I’m using node red and I can’t quite figure out how to get the webhook into node red. Please help

Is your Node Red instance accessible from the internet? Then your webhook should look something like http://(username):(password)@your.node.red.server:1881/(endpoint). And then in Node Red you use a http in node matching (endpoint) connected to an http auth node to validate the username and password. And the method (get/post) in IFTTT has to match that in the http in node (get is easier as it turns query variables into JSON) And then you’re in. And then you decide whether or not to move to https (I have not bothered).
