Hello @ezoulou
Thank you for reaching out to us, we are happy to help you out.
The issue you are facing does not sound like a plugin issue but more like an account configurational issue. This can most likely be resolved via the payment provider’s back end. For this you should review your test account on the Worldline backend page here.
At the top right, you have a group of dots, which contain a link to the “back office.” In the back office, you can go to “Configuration” –> “Payment Methods,” and here, you should be able to review and add/remove payment methods for your test account.
If you can’t find the solution for this issue, I would advise you to go (in the same back office page) to the “Support” –> “Contact” page, which should help you get support on getting your account adjusted for your purpose. Be sure to identify your PSPID and what payment method you are looking to add to this account. The PSPID should be visible on the first link I provided at the beginning of this response, under the “Accounts” drop-down menu.
Please let us know if this helped you towards the solution you need or if you need additional support.
Kind regards,
Joost
