Thanks for post! I have used the dataset API before and then looped through the output in my PowerShell. I was hoping the Capacity Refresh API allowed me to do this within a single call, using the nested json output in the $filter. My alternative using this API is to pull back a day's worth of refreshes into an object variable and drill down to the status within PowerShell. Thought I wouldn't have to do that, but maybe the code behind the API doesn't allow to filter on anything nested in the response. It would just be good to know this in their documentation so I am not wasting my time trying to figure it out.
