I've been looking at the API explorer for a while. It's a great idea: the API is poorly documented, but this would be a perfect sort of live documentation. but I never got it to work.
I can choose an entity and an action. But
add option and
chain api call dont do anything. The labels 'name','operator' and 'value' are hanging there with question marks and helptext. 'operator' says 'Choose an operator from the list', but there is no list.
Everyone seems to be happily using it...
