How to query plans with the REST api

Hello,

I was using the REST api to make queries about a user's work items and that was fine. However, I'm having troubles making queries for plans.
Is there any place where I can find documentation/examples regarding plans?




The documentation I'm using is this:
https://jazz.net/wiki/bin/view/Main/ResourceOrientedWorkItemAPIv2
(you can see by the index that it's very resourceful for
work items, but not for plans)


Thanks in advance!
