Youtube Subscribers latest video

Hello Ramco,

Try below code:

static void GetLatestVideoForSubscribedChannels(string accessToken)
{
    // Set the YouTube API base URL
    string baseUrl = "https://www.googleapis.com/youtube/v3/";

    // Create a new RestClient and set the base URL
    RestClient client = new RestClient(baseUrl);

    // Set the request parameters to retrieve the subscribed channels of the authenticated user
    RestRequest request = new RestRequest("subscriptions", Method.Get);
    request.AddParameter("part", "snippet");
    request.AddParameter("mine", "true");
    request.AddHeader("Authorization", "Bearer " + accessToken);

    // Execute the request and get the list of subscribed channels
    IRestResponse response = client.Execute(request);
    dynamic data = Newtonsoft.Json.JsonConvert.DeserializeObject(response.Content);

    // Loop through the subscribed channels and get the latest video for each channel
    foreach (var item in data.items)
    {
        // Get the channel ID and set the request parameters to retrieve the latest video uploaded by the channel
        string channelId = item.snippet.resourceId.channelId;
        request = new RestRequest("search", Method.Get);
        request.AddParameter("part", "snippet");
        request.AddParameter("channelId", channelId);
        request.AddParameter("order", "date");
        request.AddParameter("type", "video");
        request.AddParameter("maxResults", "1");
        request.AddHeader("Authorization", "Bearer " + accessToken);

        // Execute the request and get the details of the latest video uploaded by the channel
        response = client.Execute(request);
        dynamic videoData = Newtonsoft.Json.JsonConvert.DeserializeObject(response.Content);
        dynamic video = videoData.items[0];

        // Print the details of the latest video
        Console.WriteLine("Latest video uploaded by " + item.snippet.title + ":");
        Console.WriteLine("Title: " + video.snippet.title);
        Console.WriteLine("Description: " + video.snippet.description);
        Console.WriteLine("Thumbnail: " + video.snippet.thumbnails.high.url);
        Console.WriteLine("Video URL: https://www.youtube.com/watch?v=" + video.id.videoId);
        Console.WriteLine("");
    }
}
