=item B<--basic>

Specify this option if you access API over basic authentication and don't want a '401 UNAUTHORIZED' error to be logged on your webserver.

Specify this option if you access API over hidden basic authentication or you'll get a '404 NOT FOUND' error.

(Use with --credentials)

Specify username for API authentification

=item B<--password>

Specify password for API authentification
