Mise en place de Paypal pour se connecter au script

Question

J'ai, je crois, suivi les instructions de configuration correctement pour connecter paypal à mon script. J'ai un jeu qui est mis en place pour permettre aux utilisateurs d'acheter des crédits. En ce moment je dois ajouter l'information de paypal directement dans la base de données. Je reçois l'email de transaction, à la fois moi et l'utilisateur confirmant l'achat. Mais il n'apparaîtra pas dans ma base de données.Peut-être quelqu'un m'aider s'il vous plaît.

Merci Jeff
