J'intègre la passerelle de paiement payumoney sur mon application Android. Mais quand j'ai essayé de faire une transaction test avec une carte de débit test. Cela montre une erreur. quand je contacte le service client payumoney, ils ont dit de mettre l'url sur liste blanche sur le serveur. Je ne sais pas comment ajouter un serveur ito url à la liste blanche.
