Sales Order confirmation using AIF services in ax 2012 ?

Hi,

I am able to create sales order by using SalesSalesOrderService AIF Service, by using C# Code I am consuming this service and creating Salesorder in AX From C#. 

But after creating Sales order it should be confirmed. which AIF service to use to confirm sales order. I found there is a service SalesSalesConfirmationService, I think I should use this service. How to use this service if it is yes?

Thanks,
