It seems Paylib and Carte Bleue Payment Methods cannot be activated on Wallee but it is a part o the payment methods available at Mercanet Payment Gateway like Visa, MasterCard, American Express...
Do you plan to add them soon ?
Can you send us an e-mail to email@example.com regarding this request incl. your wallee account/space ID ?
I will gladly escalate this to our developers.
Thanks in advance.
