Hi Ben,

The R, Java, and Python client APIs have all been updated such that they should pass the CSRF token seamlessly to the API user. Of course, the code that's using it might need to update the version of the API library to get the new code.

The Perl API doesn't yet handle this. I've logged an issue:
