Hi Chinmaya, Below is the code for Request Token attribute public class FliteTokenAttribute : AuthorizeAttribute { public override void OnAuthorization(System.Web.Http.Controllers.HttpActionContext actionContext) { if (HttpContext.Current.Request.Headers["RequestVerificationToken"] != null) { if (AuthorizeRequest(actionContext)) { return; } } HandleUnauthorizedRequest(actionContext); } protected override void HandleUnauthorizedRequest(System.Web.Http.Controllers.HttpActionContext actionContext) { base.HandleUnauthorizedRequest(actionContext); actionContext.Response = new HttpResponseMessage(HttpStatusCode.NotAcceptable); } private bool AuthorizeRequest(System.Web.Http.Controllers.HttpActionContext actionContext) { try { string cookieToken = ""; string formToken = ""; IEnumerable tokenHeaders; if (actionContext.Request.Headers.TryGetValues("RequestVerificationToken", out tokenHeaders)) { string[] tokens = tokenHeaders.First().Split(':'); if (tokens.Length == 2) { cookieToken = tokens[0].Trim(); formToken = tokens[1].Trim(); } } AntiForgery.Validate(cookieToken, formToken); return true; } catch { return false; } } }
