Paypal IPN INVALIDE :(

[leoz2007]

Bonjour a tous,
je suis charge de mettre en place un système de payement par Paypal sur le site de notre entreprise.

Actuellement, j'ai créer un bouton sur paypal.com, hoster sur mon serveur, configurer l'ipn, test sandbox.

Je reçois bien les notifications de paypal, le payement sur mon compte est bien valider.
je n'arrive par contre pas a récupérer les valeurs de l'ipn que je souhaiterais pusher dans ma DB.

Je cherche en vain, mais IPN me renvois constamment un résultat INVALID.
