    public override void OnAuthorization(System.Web.Http.Controllers.HttpActionContext filterContext)
   {
       if (filterContext == null)
       {
           throw new UnauthorizedAccessException("Access Token Required");
       }
       base.OnAuthorization(filterContext);
       if (filterContext.ActionDescriptor.GetCustomAttributes().Any())
       {
           return;
       }
       if (filterContext.Request.Headers.Authorization != null)
       {
           var response = 
    PTPRestClient.GetRequest(filterContext.Request.Headers.Authorization.ToString(), 
    "api/validate/validate-request");
           if (!response.IsSuccessStatusCode)
           {
               throw new UnauthorizedAccessException();
           }
   
   
       }
       else
       {
           throw new UnauthorizedAccessException("Access Token Required");
       }
   }
