Авторизация с __RequestVerificationToken и cookie

Пытаюсь написать программу для парсинга неких данных с сайта, с парсингом проблем быть не должно, но от авторизации уже голова болит. Не пойму что я упускаю. 1) спарсил __RequestVerificationToken с сайта 2) получил cookie __RequestVerificationToken (два разных значения) 3) отправляю запрос авторизации (токен, cookie, логин, пароль) на адрес "https://id.bookatable.com/en-GB?returnUrl=https://erb.bookatable.com/booking-manager/en-GB" по идее должен получить ещё куки но их нет, как быть?

    public async Task<string> Login (CancellationToken ct)
        {
            string data; // declaring variables
            var baseAddress = new Uri("https://id.bookatable.com");
            var loginUrl = "en-GB?returnUrl=https://erb.bookatable.com/booking-manager/en-GB";
            var getDataUrl = "/BookingManager/getTablePlanWithBookingsFor?";
            var cookieContainer = new CookieContainer();
            using (var handler = new HttpClientHandler { CookieContainer = cookieContainer })
            using (HttpClient client = new HttpClient(handler) { BaseAddress = baseAddress })
            {
