What version of X3 are you on, and what version of .net are you using?  X3 uses basic authentication for the SOAP web services since version 8.  I believe the way to call X3 web services from SOAP is difference from .net Core, but if you are using a standard Console/WinForms/Web application, it should work with basic authentication.

Hi Denise,

do you know wich is the way to call X3 web service SOAP from .net core?

Thanks for all!

Hi Carles Homs Ferrer ,

I have an old example (10 years old) in C# based on sales order example (SOH object):

// XML Header to be included in all xml input strings
        private static string XML_HEADER = "<?xml version=\"1.0\" encoding=\"UTF-8\"?>";

        // Public name of the web service
        private static string WEB_SERVICE_NAME = "SOH";

        public Orders()
        {
            InitializeComponent();

            // Initialise connection values
            callContext = new CAdxCallContext();
            webService = new CAdxWebServiceXmlCCService();
            paramKey = new CAdxParamKeyValue[1];
            resultXML = new CAdxResultXml();

            callContext.codeLang = "BRI";          // Connection language
            callContext.codeUser = "admin";        // X3 user
            callContext.password = "";             // X3 password
            callContext.poolAlias = "WS_DEMOBRI";  // Connection pool name
        }

        /// <summary>
        /// This is called when the Read button is clicked.

        {
            // Complete call context depending on flags
            if (DisplayTraceFile.Checked)
                callContext.requestConfig = "adxwss.trace.on=on&adxwss.trace.size=16384&adonix.trace.on=on&adonix.trace.level=3&adonix.trace.size=8";
            else

            // Prepare paramKeyValue
            paramKey[0] = new CAdxParamKeyValue();
            paramKey[0].key = "1";  // Other method: paramKey[0].key = "SOHNUM";
            paramKey[0].value = SOHNUM.Text;
            // When more than one field in the object key, complete as follows:
            // paramKey[1] = new CAdxParamKeyValue();
            // paramKey[1].Key = "2";
            // paramKey[1].value = ...

            // Call web service
            resultXML = webService.read(callContext, WEB_SERVICE_NAME, paramKey);

            displayMessages(resultXML);

            if (resultXML.status == 0)
            {
                Status.Text = "Status: NOT OK";
            }

                displayData(resultXML);
            }

        }

Hello Bruno Gonzalez ,

thanks for the answer. In .Net core the class CAdxWebServiceXmlCCService are no accessible:

The way to reference WSDL is different and I suspect this affects the way I use it.

I don't know how .Net core works, but I bet it has to do with how the WSDL was declared and the code generated.
