Can you add some additional specifics? Are you looking for where to get the ip address? There are a couple of methods one is getting the ip address that vRA is managing and the other is querying the vm itself for that information. In theory both should be the same but could differ.
I found my problem(s) I forgot to add Extensibility.Lifecycle.Properties.VMPSMasterWorkflow32.MachineProvisioned and change the wording of my get command. Two simple mistakes.
