Help understanding how to receive a callback from a REST API

I want to implement the Webhook APIs from using ASP .NET Core 2.1 Web API, but I'm not sure how to configure this to test in Visual Studio 2017 IDE. Since it requires me to configure an application URL where it will send callbacks to my APIs, how can I set this up locally for debugging when IIS Express uses localhost as the site name? Will I need a public facing webserver/site to publish my code to?

Run my application, leave it running, and wait for the callback?

You can test your API's through Postman (need to install)  locally.
