Retrieving extra attributes

Trying to pull data from Prime's REST API, and facing some difficulties: 

•  Need to be able to specify extra attributes for which would like to retrieve data, currently got the following two URLs for getting details from Wireless Controllers: 
• <primeUrl>/webacs/api/v1/data/InventoryDetails/16816800?.full=true?.ctx_domain=root
• <primeUrl>/webacs/api/v1/data/Devices/16816800?.full=true 

And got some good data, but can't retrieve the last successful poll time, or the MAC address. 

• specifying '.full=true', so able to understand that you are getting what Prime describes as a 'full' dataset, but is there any way to get further information from the API.

Alex, if you're specifying .full=true then you're getting all the data that resource can return.  However, if you're looking for info specifically about Wireless Controllers, then you should check out the Wlan Controller Summary and Wlan Controller Details resources.
