This document summarizes Dirk Köhler's presentation at the Hanseatic Bank Integration Summit 2019 on their journey implementing PSD2 and Open Banking standards. It discusses how they used the WSO2 Open Banking platform to create a consistent API architecture with standardized interfaces. This helped enable easy onboarding of third-party providers and new business opportunities. Some challenges included addressing security concerns in financial services and adapting to their previously siloed organizational structure. Next steps include expanding their API strategy to develop new strategic partnerships and products.
