Handler route in web.api - asp.net

Question

I have web.api 2 project. I also tried to add handler to it. But every request (http://api.xxxx.xxx/handler) which I send return error of 404 code. I realized that problem is route config, but how I can fix it?
web.config
<system.webServer>
<validation validateIntegratedModeConfiguration="false" />
<modules runAllManagedModulesForAllRequests="true">
<remove name="WebDAVModule" />
<!-- ADD THIS -->
</modules>
<handlers accessPolicy="Read, Execute, Script">
<remove name="ExtensionlessUrlHandler-Integrated-4.0" />
<remove name="OPTIONSVerbHandler" />
<remove name="TRACEVerbHandler" />
<add name="ExtensionlessUrlHandler-Integrated-4.0" path="*." verb="*" type="System.Web.Handlers.TransferRequestHandler" preCondition="integratedMode,runtimeVersionv4.0" />
<add name="ChatHandler" verb="*" path="/handler/" type="ProjectAPI.Handler.ChatHandler" />
</handlers>
</system.webServer>
Global.asax.cs
public class WebApiApplication : System.Web.HttpApplication
{
protected void Application_Start()
{
RouteTable.Routes.Ignore("{resource}.axd/{*pathInfo}");
RouteTable.Routes.Ignore("handler/{*path}");
GlobalConfiguration.Configure(WebApiConfig.Register);
}
}

If you didn't changed the WebApiConfig routes, the default url should be:
http://api.xxxx.xxx/api/handler. I've never see a need to add this to the configuration, why's that? Change only the configuration in the WebApiConfig.Register from ~/api/ to ~/ and it should work. Post some more code, because it's like "reading from the tea leaves" :)
