Hi @Maximus !
There are no stupid questions here!
Long story short, a webhook is a way for an app to provide other applications with real-time information. It is a callback that “lets your app know” when something happens. In this case, when “Halo” changes to “CREATE”, a webhook will be sent to the URL you provided. You will need to listen to that URL so that you get the payload from the webhook. I have not used this in Zapier but from what I can see, I believe you can choose the option “Catch Hook”:
Which should create a zapier URL for you. And then use that URL as your webhook URL in Monday so that when the trigger occurs, the webhook can be sent to that Zapier URL and that can trigger the action.
As I said I do not count with a premium Zapier account to try this at the moment so I can’t assure this will work as intended, but it looks like it could be what you are looking for.
Please do let me know if this works and if you have any more questions!
