finding ProgramInstances in the webapi

Hi all,

I’m trying to access Program Instances for a Tracked Entity Instance using the WebAPI because I’m enrolling to stages in a mobile client, and I need to set duedate for which I need the registration date of the Program Instance. I couldn’t find it browsing the api, and I couldn’t find it in api/events, although I can easily find the Program Stage Instances. Is it possible to access it somehow? Perhaps I’m just not seeing it. A list of all Program Instances would be good for bulk loading, and for a single Tracked Entity Instance on demand but I don’t know what’s possible.
