We currently have several VB.net applications that make use of the Administrative API in GroupWise 2008 for removing and adding items from the document profile lookup list. We are now exploring the possibility of migrating to GroupWise 2014. Since the Admin API is no longer available in GroupWise 2014, I need to rewrite the code using the REST API. I've never worked with any kind of web services before and I don't even know how to start writing the code.

Where can I find example of code or scripts that will perform the same actions mention above using the REST API in VB.net? I've downloaded the SDK and I did not find any useful information that will help we create the code mentioned above.
