As with every method we need to pass in credentials. We do this with the LookupUser request object.

We will assume you have a web reference, let us name it SWS, in your Visual Studio project. At this point we need to define our objects.  We will need the standard service object, a VoidTransaction request object, and a VoidTransaction response object. We can define and create those like this:

// Create a request and response objects
SWS.WSSoapClient service = new SWS.WSSoapClient();
SWS.VoidTransaction_Request request = new SWS.VoidTransaction_Request();
SWS.VoidTransaction_Response response;

Here is a sample code of the request object:

// VoidTransaction Request
request.OrgID = 123456;
request.SiteID = 123546;
request.AccountID = 123456;
request.AccountName = "Doe, John";
request.Amount = 55.26m;
request.TransactionID = 123546;
request.TransactionDate = new DateTime(2016, 2, 3);
request.Ledger = SWS.LedgerType.Rental;

Finally we can call the method and pass across the login object and the request object to retrieve our requested information. It’s a good idea to do this in a Try Catch block.

// Call the method that will load the response object
  response = service.VoidTransaction(user_request, request);
catch (Exception ex)

Note that if something goes wrong the service will respond with an exception. You will want to capture the message in the exception so it can be debugged.
