WebAPI : NTLM authentication in Ax2012 R3

Hi,

I'm actually trying to call a WebAPI from code.

The API is running on a IIS which has Windows Authentication activated

I've tried to call it in a job with the code below :

static void TestApi(Args _args)
{
    str                             url;
    str                             byteStr;
    System.Net.HttpWebRequest       request;
    System.Net.HttpWebResponse      response;

    System.Byte[]                   byteArray;
    System.IO.Stream                stream;
    System.IO.Stream                dataStream;
    System.IO.StreamReader          streamReader;
    System.Net.ServicePoint         servicePoint;
    System.Net.WebHeaderCollection  httpHeader;
    CLRObject                       clrObj, ex;
    System.Text.Encoding            utf8;
    xml responseXml;
    ;

    byteStr = strfmt('%1:%2', "toto", "tata");
    new InteropPermission(InteropKind::ClrInterop).assert();
    httpHeader = new System.Net.WebHeaderCollection();
    url = "http://atl-svax016.atelier.lan:8080/api/DMDLOG/Information/CHG-0000004536";
    clrObj      = System.Net.WebRequest::Create(url);
    request     = clrObj;
    request.set_Method("GET");
    request.set_KeepAlive(true);
    request.set_ContentType("application/json");
    utf8        = System.Text.Encoding::get_UTF8();
    byteArray   = utf8.GetBytes(byteStr);
    byteStr     = System.Convert::ToBase64String(byteArray);
    httpHeader.Add("Authorization", 'NTLM '   byteStr);
    

    try
    {
        request.set_Headers(httpHeader);
        response = request.GetResponse();
        dataStream = response.GetResponseStream();
        streamReader = new System.IO.StreamReader(dataStream);
        responseXml  = streamReader.ReadToEnd();
        info(responseXml);
    }
    catch (Exception::CLRError)
    {
        ex = ClrInterop::getLastException();
        if (ex != null)
        {
            ex = ex.get_InnerException();
            if (ex != null)
            {
                error(ex.ToString());
            }
        }
        else
            throw error ("Error while connecting API");

    }

    streamReader.Close();
    dataStream.Close();
    response.Close();
}

But when I execute it i get the error below :
