Receive and handle dynamics 365 webhook

Question

I'm building this application that creates a webhook on dynamics CRM whenever a new contact is created. I've been following this guide Receiving WebHooks in your web application and ASP.NET WebHooks - receiving and processing. I'm using requestbin to check if the webhook is actually created, and it works. The webhook is created. Problem is, i dont understand how to receive the data in my windows form. I've added this into my App.config

<appSettings>
       <add key="MS_WebHookReceiverSecret_dynamicscrm" value="12345678901234567890123456789012"/>
</appSettings>

I've also created two classes:

• WebHookRegister: Registers the dynamics CRM webhook

  public static class WebHookRegister
  {
      public static void Register(HttpConfiguration config)
      {
          config.MapHttpAttributeRoutes();
  
          config.Routes.MapHttpRoute(
              name: "DefaultApi",
              routeTemplate: "api/{controller}/{id}",
              defaults: new { id= RouteParameter.Optional }
          );
  
          config.InitializeReceiveDynamicsCrmWebHooks();
      }
  }
  

• DynamicsWebHookHandler: Gets the data from the webhook ( for now im doing nothing with it, later i will use it do to stuff ).

  public class DynamicsWebHookHandler : WebHookHandler
  {
      public override Task ExecuteAsync(string receiver, WebHookHandlerContext context)
      {
           JObject data = context.GetDataOrDefault<JObject>();
  
           return Task.FromResult(true); 
      }
  }
  

Last thing i've done is register my webhook in the program ( right after my form is initialized, by calling this:

WebHookRegister.Register(new HttpConfiguration());

I know by reading the guide that the webhook receiver URI must be created as follows: https://<host>/api/webhooks/incoming/<receiver>/{id}, but I'm not understanding where to create it in the code.

Thanks for any help
