NetApp SDK and API

First, some important documentation: here is a good document for the Powershell Toolkit, and all SDK Documentation can be found here.

Here is the NetApp SDK: http://community.netapp.com/t5/Developer-Network-Articles-and-Resources/NetApp-Manageability-NM-SDK-Introduction-and-Download-Information/ta-p/86418

  

In the SDK you'll find a help file.  

But the really useful information is buried a bit here:

Where you'll find info on all the objects and methods available!

Also here is the developer network community site: http://community.netapp.com/t5/Developer-Network/ct-p/developer-network.  You'll find the developer community site the most helpful of all of them by a long shot!
