[ckan-discuss] Basic CKAN API question

Tue Apr 23 21:07:58 BST 2013

The shortest hack to get it working even with old CKAN versions is http://datahub.io/api/3/action/group_list?{}.

Specifically, I'm trying to fetch the list of groups from datahub.io so I don't have to page through the list manually (it's not in alphabetical order, at least not by group name). But when I follow the docs and go to http://datahub.io/api/3/action/group_list I get the message below.
