var response = await pdfApi.PostDocumentPagesResizeAsync(storageFileName, 300, 200, "1,3-5,8", folder: storageTempFolder);
if (response == null)
Console.WriteLine("ResizeDocumentPages(): Unexpected error!");
else if (response.Code != 200)
Console.WriteLine("ResizeDocumentPages(): Error -> Code {0} -> Status '{1}'", [response.Code, response.Status]);

using Stream downloadStream = pdfApi.DownloadFile(Path.Combine(storageTempFolder, storageFileName));
using FileStream localStream = File.Create(Path.Combine(localFolder, resultFileName));
downloadStream.CopyTo(localStream);
