The document discusses establishing an API Center of Excellence for banks to develop and implement their APIs and open banking strategy. It recommends creating an API developer portal to engage with developer communities to understand potential and refine strategy.

It advises working with a forward-thinking partner to access skills and expertise needed to continually innovate APIs and shape strategies.
