Not sure if I'm missing something, but it appears that I can't access the custom picklists that have been added to my organization's 'Cases' type via the API. 

I've inspected the returns from the getFields method ( https://www.zoho.com/crm/help/api/getfields.html), as well as the returns from the getRecords method ( https://www.zoho.com/crm/help/api/getrecords.html), but neither of these show the field I'm looking for.

Is this not supported, or is there something I'm missing in my call signature?
