[Apiman-user] Billing

Hi all, I'm quiet new to apiman, using it just from 3 days. I find it suuper easy and complete. I've seen that billing is a possible use case, however I can't find any tutorial about how to implement it. Should I add a plugin? or should I code it? Thank you for your help :) Regards -- Cordialement IjlaL EL HAZITI *Etudiant Ingénieur Etudes et Développement* *UBO - Master Professionnel de développement à l'offshore des SI* *FSK - Master Spécialisé Qualité du Logiciel*
