Your Axepta Online payment solution is implemented via
Axepta Plugin : Prestashop/Magento/Woocommerce
In your plugin Back Office, in Configuration du compte : If the "Demande d'exemption 3DSecure" field is present, it means that you are compliant with 3DSV2 so no action is required.
If this field is not there, an update of your plugin is required.
