Qwist is using the bank’s PSD2 API. This means that when you inquire about issues with your online banking, the bank will only check the online banking system. You need to explicitly mention that you are trying to connect your bank account via the PSD2 API if your access is blocked or if different login credentials or permissions are required.
If you have already confirmed with your bank that PSD2 API access has been enabled and you are still having trouble with this issue, contact the Payhawk Support team via chat or by sending an email to support@payhawk.com.
