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

We’ll assume you’ve got a web reference, let’s name it SWS, in your Visual Studio project.  At this point we need to our objects.  We’ll need the standard service object, a RollbackUnitTransfer request object and a RollbackUnitTransfer response object. We can define and create those like this:

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

Here’s my sample code of the Request object.

// RollbackUnitTransfer Request
request.OrgID = 123456;
request.TransactionID = 123456;

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

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

Note that if something goes wrong the service will respond with an exception. You’ll want to take a look at that message returned in that exception so it can be debugged.
