On the following page:
http://studios.thoughtworks.com/mingle/2.0/help/mingle_api.html

All of the references have ’/project/’ in the URI.
... user:password@your.mingle.server:8080/project/example_project/cards/ ...

Correct me if I’m wrong, but shouldn’t that be ’/projects/’ with an s at the end?
... user:password@your.mingle.server:8080/projects/example_project/cards/ ...

Hello Thomas – this has been fixed in the latest version of the help. Thanks for bringing this to our attention.
