We are releasing the enhancement to our Open Banking APIs where we will support eIDAS certificates in both test facility and in the production environments. TPPs may on-board with us using eIDAS certificates issued by Open Banking (OBWAC/OBSeal) or issued by a QTSP (QWAC/QSeal). TPPs on-boarded with us already using legacy Open Banking certificates may continue using their clients without any change.
There should not be any major impact on the existing services during the release window. If you have any questions and/or concerns, please get in touch with our open banking technical team at OpenBankingSupport@vanquisbank.co.uk.
Please refer to our updated implementation guide for details at
