I'm doing some tests with demo.ckan.org, which is running the 2.4 version of the API, AFAIK. Everything works well (organization and dataset creation) except for the resource creation. The resource_create method always returns a 500 error.
This is the curl showing the package where I want to create the resource:
$ curl -X GET "http://demo.ckan.org:80/api/3/action/package_show?id=f2c4125b-27c8-4e07-94d7-d6d0c0b65154" | python -m json.tool

And the curl failing when trying to create the resource:

This appears to be a documentation (and code) bug.
Although format is marked as optional in the documentation, the code requires it to be present (and will unfortunately crash if it isn't).
I've created a ticket at https://github.com/ckan/ckan/issues/2665
As a temporary measure until this is fixed, you can specify the "format" in the JSON you send (it can be empty).
