How I make a webhook in my custom app with Laravel

[gabrielravelo]

I want to make a webhook when a client create an order, I get the information of that order to create the same order in my own system, I read the doc but I don't really have an idea to how proceed, because the custom app is made in Laravel but the frontend is with Reactjs, there is a video of example or something/someone that help me with this?

Yes, but what url I put in the webhook? I need to create a route in the
web.php of my app or what?
