Know the Name of the Service Data Object.
Know the parameters you need and their values.
Define success and error callback functions. Of course, you can define these anonymously in the actual call to executeDataObject(), but that call will be more succinct and readable if you define them separately.
Call Aptify.framework.dataObjects.executeDataObject() to execute the Service Data Object.
Best practice is to check that Aptify Web is actually online before making the call, since the Service Data Object is executed on the server side.
