There doesn’t appear to be a way to enable or disable Applications via the API. I would guess maybe this would be a combination of GET (to query current settings) and POST to change them, to something like /api/v0/devices/:name/applications/ ? Bonus points if we can even directly access / adjust individual applications as /api/v0/devices/:name/applications/:application rather than having to grab the entire list, adjust one entry in it, and send that back.
