No, you can do it all in managed code.

Sandbox/Live transaction URL:

private string PostingURL
    {
      get
      {
        if (_testMode)
          return @"https://test.authorize.net/gateway/transact.dll";
        else
          return @"https://secure.authorize.net/gateway/transact.dll";
      }
    }

To post:

public void Post()
    {
      string postURL = this.PostingURL;
      string args = GetPostUrlArgs();
      string result = string.Empty;

      HttpWebRequest objRequest = (HttpWebRequest)WebRequest.Create(postURL);
      objRequest.Method = "POST";
      objRequest.ContentLength = args.Length;
      objRequest.ContentType = "application/x-www-form-urlencoded";

      StreamWriter myWriter = null;
      try
      {
        myWriter = new StreamWriter(objRequest.GetRequestStream());
        myWriter.Write(args);
      }
      finally
      {
        myWriter.Close();
        myWriter.Dispose();
      }

      HttpWebResponse objResponse = (HttpWebResponse)objRequest.GetResponse();
      using (StreamReader sr = new StreamReader(objResponse.GetResponseStream()))
      {
        result = sr.ReadToEnd();
        sr.Close();
        sr.Dispose();
      }

      this.Response = new CcTxResponse(result);

The posting arguments (You should probably use a string builder instead of string.Format() but I didn't realize how long it would be when I started):

private string GetPostUrlArgs()

1) Stop hitting reply with all that code in it. It makes the thread too long
2) This thread is solved and the new question you are asking is a different topic. Start a new thread
3) What is your question about recurring billing? (put this in the NEW thread).

This question has already been answered. Start a new discussion instead.
