Banking
Banking is OP’s largest business segment providing customers with a comprehensive range of products and services.
PSD2 regulation has obliged European banks to open their APIs to Third Party Providers, which brings a big shift in banking. We consider this a great opportunity to collaborate with FinTechs and startups and expand the services we offer our customers.
However, open banking is more than just PSD2. We are dedicated to continously develop our selection of high-quality banking APIs that would best meet our partners' needs. Our premium APIs include, for example, OP Online Payment API and OP Corporate Banking APIs.
