Comment valider les webhooks
Les developpeurs peuvent facilement valider les webhooks reçus de la plateforme Bictorys en suivant les étapes suivantes :
Verifier le header X-Secret-Key
Chaque notification envoyée inclut le header X-Secret-Key qui contient la valeur de la clé secrete du webhook que vous avez renseignée sur votre dashboard. Vous devez verifier que la clé secrete envoyée correspond à la clé secrete enregistrée sur votre compte Bictorys avant de continuer le traitement.
Vérification des Données de la Transaction
Il est nécessaire de s'assurer que des éléments clés tels que le montant, la devise (currency), le statut de la transaction, et la référence de paiement le cas échéant sont bien présents et corrects dans la payload (données transmises).
Validation de la Commande
La commande ne doit être validée que lorsque votre système reçoit un appel de webhook (une notification automatique) confirmant le statut de la transaction. Cela garantit que le paiement a été traité avec succès avant de finaliser la commande.
