无法在Klipfolio上验证SSO

Question

我正在研究Klipfolio的SSO。我正在使用restsharp进行SSO。一切都很完美，我得到了成功的回应。我还收到了cookie作为回应，但无法重定向到他们的仪表板。 这是我的代码

            var client = new RestClient("https://app.klipfolio.com/users/sso_auth");
            var request = new RestRequest(Method.POST);
            request.AddHeader("cache-control", "no-cache");
            request.AddHeader("content-type", "application/json");
            request.AddParameter("KF-SSO", AuthData["KF-SSO"]);
            request.AddParameter("KF-Company", AuthData["KF-Company"]);
            response = client.Execute(request);
            CookieContainer CookiesContainer = new CookieContainer();
            if (response.StatusCode == HttpStatusCode.OK) {
                foreach (var Cookie in response.Cookies)
                {
                    CookiesContainer.Add(new Cookie(Cookie.Name, Cookie.Value, Cookie.Path, Cookie.Domain));
                }
            client.CookieContainer = CookiesContainer;
            KlipfolioDataModel objKlipfolioDataModel = JsonConvert.DeserializeObject<KlipfolioDataModel>(response.Content);
            return objKlipfolioDataModel;
            }
            else
               return new KlipfolioDataModel();

如果我从AJAX做同样的事情，我可以重定向到Klipoflio仪表板

function ssoAuth() {
    $.ajax({
        url: "https://app.klipfolio.com/users/sso_auth",
        type: "post",
        async: false,
        xhrFields: {
            withCredentials: true
        },
        headers: {
            "KF-SSO": ssoToken,
            "KF-Company": ssoCompany
        },
        dataType: "json",
        success: function (data) {
            console.log(data);
        },
        error: function (err) {
            console.log("sso auth failed", err)
            var errMsg = JSON.parse(err.responseText);
            console.log(errMsg)
            $('#result').html("<h2 class='fail'>SSO Failed<h2><p>Error: (#" + errMsg.error_code + ") "
                + errMsg.error_message + "</p>");
        }
    })
}

我不知道我哪里错了？帮我理清这件事。
