Solution

  • to download Yammer attachments you need both Download URl and Access token as below

      string Path = @"C:\SocialMediaDownloads\Yammer\Attachments\"+MessageId; 
  bool isExists = System.IO.Directory.Exists(Path);
  if (!isExists)
        System.IO.Directory.CreateDirectory(Path);

        WebClient client = new WebClient();
        client.BaseAddress = "https://www.yammer.com";
        client.Headers["Authorization"] = "Bearer " + accessToken;
        client.DownloadFileCompleted += new AsyncCompletedEventHandler(client_DownloadDataCompleted);
        client.DownloadFileAsync(new Uri(URL),Path+@"\"+FileName);
        return Path;
    }
