I want to write a small app that polls for any open urgent tickets.

The API shown here http://freshdesk.com/api/tickets/ shows methods for getting every ticket, and getting all tickets for a user by email.

I was wondering if there was some options that aren't currently documented, such as by priority and/or by status.

If not I can still just grab every ticket ever and scan through using XPath but that causes a bit more of a burden on bandwidth than I would like to avoid if possible.
