// URL of your public interface, with query parameter to which the long URL will be passed

define( 'OZH_PUBPNF_URL', 'https://shor.rt/public.php?url=%' );

yourls_add_action( 'load_template_redirect_admin', 'ozh_pubpnf' );

You must have a public interface up and running, duh. For instance rename the provided sample public interface to public.php and edit its look and feel to suit your needs.

This public interface must accept a long URL as a query parameter (for instance 'url' as in the sample provided). Edit OZH_PUBPNF_URL to reflect the public interface location and the parameter name.
