Authentication Soap Api Header c#

Question

i'm trying to call a soap api but i can't authenticate. The api should recive an xml like this in the header:

<wsse:Security> <wsse:UsernameToken> <wsse:Username>XXXXXXXXX</Username> <wsse:Password>XXXXXXXXX</Password> </wsse:UsernameToken> </wsse:Security>

But i don't understand how to pass it, i'm trying to insert the credential in this way:

 client.ClientCredentials.UserName.UserName = "XXXXXXXXX"; client.ClientCredentials.UserName.Password = "XXXXXXXXX";

And then build the binder in this way:

 BasicHttpsBinding bindingHttps = new BasicHttpsBinding(); bindingHttps.Security.Mode = BasicHttpsSecurityMode.Transport; bindingHttps.MaxReceivedMessageSize = 500000000; bindingHttps.SendTimeout = new TimeSpan(0, 5, 0);

But the call return this error: System.AggregateException: 'One or more errors occurred. (Error: UsernameToken not present)'

Try following :

using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Xml; using System.Xml.Linq; //This is Xml you need to generate //<? xml version = "1.0" ?> //<soapenv:Envelope xmlns:wsse="http://schemas.xmlsoap.org/soap/envelope/" > // <wsse:Header > // <wsse:Security > // <wsse:UsernameToken > // <wsse:Username > XXXXXXXXX </ Username > // <wsse:Password > XXXXXXXXX </ Password > // </wsse:UsernameToken > // </wsse:Security > // </wsse:Header > // <wsse:Body > // <yourbodygoeshere > // </wsse:Body > //</wsse:Envelope > namespace ConsoleApplication23 { class Program { const string FILENAME = @"c:\temp\test.xml"; static void Main(string[] args) { string username = "John"; string password = "1234567890"; string ident = "<?xml version=\"1.0\"?><wsse:Envelope xmlns:wsse=\"http://schemas.xmlsoap.org/soap/envelope/\"></wsse:Envelope>"; XDocument doc = XDocument.Parse(ident); XElement envelope = doc.Root; XNamespace wsseNs = envelope.GetNamespaceOfPrefix("wsse"); XElement header = new XElement(wsseNs + "Header"); envelope.Add(header); XElement security = new XElement(wsseNs + "Security", new XElement(wsseNs + "UsernameToken", new XElement(wsseNs + "Username", username), new XElement(wsseNs + "Password", password) ) ); header.Add(security); XElement body = new XElement(wsseNs + "Body"); envelope.Add(body); } } }

If I use the builder in this way, it work.

var binding = new BasicHttpBinding(BasicHttpSecurityMode.TransportWithMessageCredential); binding.Security.Message.ClientCredentialType = BasicHttpMessageCredentialType.UserName;
