I'am a beginner with shopify so i use this tutorial to create my first app (https://shopify.dev/tutorials/build-a-shopify-app-with-node-and-react) and check the github project( https://github.com/Shopify/shopify-demo-app-node-react/blob/master/server.js).
I have a issue with my webhook. I try to create a webhook (carts/create) but nothing. I can't received the webhook? Someone can explain me why it did'nt work.
