How do I figure out how to call Sotlayer Service API
<p>How could I figure out what to pass as inputs for the various SoftLayer Services?</p>

<p>I know how to create the objects to call these commands, but it's unclear what to pass into these API references. Am I missing some sort of documentation or is there a discrete way to figure it out?</p>

<p>Up until now I have basically been guessing and looking at how the managers call related functions, but in this case, no manager uses this service or particular function. </p>
