Trello API: How can I modify a checklist?

Question

I have a Trello card and it has a checklist with several items. I am looking for a way to update the items' state, with either complete or incomplete. Basically the equivalent of if you were to click on it in the UI.

From the what I can see in the docs, there is no call that does a PUT or POST for a checkItem. The closest I see is the method below, but that would seem to allow you to just add a checkItem to the list.

POST /1/checklists/[idChecklist]/checkItems

Answer 1

For various embarrassing legacy reasons, it has to be done through the /1/card/checklist/... routes. The documentation for that is here:
