Cannot set a URI for generic webhooks with a route different than /api/*

[cale-sweeney]

I cannot seem to find a way to set a URI like this for generic webhooks with a route that begins with something like /portalapi/v1/*. E.g. something like this:

            config.Routes.MapHttpRoute(
                name: "PortalApi",
                routeTemplate: "portalapi/v1/{controller}/{id}",
                defaults: new { id = RouteParameter.Optional }
            );

The webhook receiver only seems to respond to posts from URIs in the form api/*:

           config.Routes.MapHttpRoute(
                name: "DefaultApi",
                routeTemplate: "api/{controller}/{id}",
                defaults: new { id = RouteParameter.Optional }
            );

Am I missing something? Or is this a bug? Has anyone been able to change the beginning of the route and have it accepted by the webhook call?

Looks like that URI is hard coded here: https://github.com/aspnet/WebHooks/blob/master/src/Microsoft.AspNetCore.WebHooks.Receivers/ApplicationModels/WebHookSelectorModelProvider.cs#L144-L153

I think you should add to the documentation that the base of the URI "/api/webhooks/incoming/" cannot be modified.
