I am creating a public app on my development store and it contains the webhook for orders/create.
I am using ngrok tunnel for my local testing and in that environment the webhook works as expected, but once I deployed it on our server the webhook throws the 503 service unavailable exception but the service is exists.
I have tried the webhook url on postman and that is working fine as well. But why the same was not working once deployed on server.
Please advice. Thanks in advance
