**How To Reproduce (If applicable)**

        public static async Task<string> PostTogetToken<T>(string requestUrl, string code, string client_Secretkey) {

            ZoomToken hello = new ZoomToken();
            var EncodedURl = ApiService.Base64Encode(client_Secretkey);

         
                using (var _httpClient = new HttpClient()) {
                    if (!string.IsNullOrEmpty(requestUrl))
                        _httpClient.DefaultRequestHeaders.TryAddWithoutValidation("Authorization", "Basic " + EncodedURl);

                    var httpContent = new StringContent("", Encoding.UTF8, "application/x-www-form-urlencoded");

                    var httpRequestMessage = new HttpRequestMessage(HttpMethod.Post, new Uri(requestUrl)) {
                        Version = HttpVersion.Version10,
                        Content = httpContent
                    };


                    using (var response = await _httpClient.SendAsync(httpRequestMessage)) {
                        if (response.IsSuccessStatusCode) {
                            response.EnsureSuccessStatusCode();
                            return await response.Content.ReadAsStringAsync();
                        } else {
                            return await response.Content.ReadAsStringAsync();
                        }
                    }
                }
        }


It actully get stuck or await from var response = await _httpClient.SendAsync(httpRequestMessage).

Hey @sumitonemail2,

Have you followed the OAuth guide here: https://marketplace.zoom.us/docs/guides/auth/oauth ?

Thanks,
