When I upload video to YouTube using client side login. The first time redirect to UI for permissions.

I want upload without redirect to web page. I need to execute this code on server.

Here is my code.

    private async Task<string> Run(string title, string description, string filepath)
        {

            var videoID = string.Empty;
            try
            {
                logger.Info(string.Format("[uploading file on youTube Title: {0}, Description: {1}, filePath: {2}]", title, description, filepath));
                UserCredential credential;
                using (var stream = new FileStream("client_secret.json", FileMode.Open, FileAccess.Read))
                {
                    logger.Info("[Load credentials from google start]");
                    credential = await GoogleWebAuthorizationBroker.AuthorizeAsync(
                        GoogleClientSecrets.Load(stream).Secrets,
                        // This OAuth 2.0 access scope allows an application to upload files to the
                        // authenticated user's YouTube channel, but doesn't allow other types of access.
                        new[] { YouTubeService.Scope.YoutubeUpload },
                        "user",
                        CancellationToken.None
                    );
                    logger.Info("[Load credentials from google end]");

                }
                logger.Info("YouTubeApiKey {0}", System.Configuration.ConfigurationManager.AppSettings["YoutubeApiKey"]);
                var youtubeService = new YouTubeService(new BaseClientService.Initializer()
                  {
                      HttpClientInitializer = credential,
                      ApiKey = System.Configuration.ConfigurationManager.AppSettings["YoutubeApiKey"],
                      ApplicationName = System.Configuration.ConfigurationManager.AppSettings["ApplicationName"]
                  });

                logger.Info("ApplicationName {0}", System.Configuration.ConfigurationManager.AppSettings["ApplicationName"]);


                var video = new Video();
                video.Snippet = new VideoSnippet();
                video.Snippet.Title = title;
                video.Snippet.Description = description;
                //video.Snippet.Tags = new string[] { "tag1", "tag2" };
                // video.Snippet.CategoryId = "22"; // See https://developers.google.com/youtube/v3/docs/videoCategories/list
                video.Status = new VideoStatus();
                video.Status.PrivacyStatus = "public"; // or "private" or "public"
                var filePath = filepath; // Replace with path to actual movie file.


                 using (var fileStream = new FileStream(filePath, FileMode.Open))
            {
                var videosInsertRequest = youtubeService.Videos.Insert(video, "snippet,status", fileStream, "video/*");
                videosInsertRequest.ProgressChanged += videosInsertRequest_ProgressChanged;
                videosInsertRequest.ResponseReceived += videosInsertRequest_ResponseReceived;

                await videosInsertRequest.UploadAsync();

            }
                return videoID;
            }
            catch (Exception e)
            {
                logger.ErrorException("[Error occurred in Run ]", e);
            }
            return videoID;
  }

        void videosInsertRequest_ProgressChanged(Google.Apis.Upload.IUploadProgress progress)
        {
            switch (progress.Status)
            {
                case UploadStatus.Uploading:
                    Console.WriteLine("{0} bytes sent.", progress.BytesSent);
                    break;

                case UploadStatus.Failed:
                    Console.WriteLine("An error prevented the upload from completing.\n{0}", progress.Exception);
                    break;
            }
        }

        void videosInsertRequest_ResponseReceived(Video video)
        {
            Console.WriteLine("Video id '{0}' was successfully uploaded.", video.Id);
        }
