.Net C# SOAP Web Service Client Example for SAP PI/PO Services

I was helping a friend connecting to a PO Web Service from .Net. It was not straightforward enough and I haven’t found a good example so I decided to share the code with you. For simplicity, It is a console application.

(Update: If you are using .Net Core or .Net version > 5, check out my other post here)

Features are:

• Using SOAP 1.1
• Basic authentication over HTTP
• Specifying endpoint

First, we add a Service Reference

We can give a Web URL or file path:

Add your C# namespace to the main class.

using ConsoleApplication4.ServiceReference2;

And the example code block:

static void Main(string[] args)
{

	BasicHttpBinding binding = new BasicHttpBinding();
	binding.Security.Mode = BasicHttpSecurityMode.TransportCredentialOnly;
	binding.Security.Transport.ClientCredentialType = HttpClientCredentialType.Basic;

	EndpointAddress endpoint = new EndpointAddress("http://hostname:port/XISOAPAdapter/MessageServlet?senderParty=&senderService=BC_SENDER_SYSTEM0&receiverParty=&receiverService=&interface=SI_SEND_ORG_DATA&interfaceNamespace=http://example.com/HR/OrganisationData");
	SI_SEND_ORG_DATAClient client = new SI_SEND_ORG_DATAClient(binding, endpoint);

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

	ZHRS_SEND_ORG_LINE[] result = client.SI_SEND_ORG_DATA("1234");

	System.Console.WriteLine(result[0].VORNA);
	System.Console.ReadLine();
}

If you have any questions, please ask in the comments.
