Open Banking APIs and Financial Aggregator APIs are the two main approaches that have gained prominence within the U.S. Although both approaches aim to facilitate access to financial data, each of the APIs have unique characteristics that must be taken into consideration. As technology directors and chief technology officers search for the optimal solution for their organizations, they are also discovering opportunities to improve the customer experience, optimize operations and drive innovation.
Open Banking APIs: Fostering Open Innovation
Driven by regulations, such as the revised Payment Services Directive (PSD2) in Europe and similar initiatives in the U.S., Open Banking APIs promote transparency and competition within the financial services sector. These APIs are developed by banks themselves or authorized third parties, allowing the secure sharing of customer data between financial institutions and third parties, such as financial technology (fintech) companies, as well as other organizations.
Main advantages of Open Banking APIs:
-
Controlled and Secure Access: Allow customers to share their financial data securely, with valid legal consent.
-
Stimulate Innovation: Facilitate the creation of new financial services and improvements surrounding the customer experience and boosting Open Innovation.
-
Regulatory Compliance: Adhere to data protection and privacy regulations, such as the EU’s General Data Protection Regulation (GDPR) of 2018 in the European Economic Area and the California Consumer Privacy Act (CCPA) of 2018 in the U.S., ensuring legal compliance.
Implementation Examples:
-
APIs that allow the integration of payment platforms between different banks.
-
APIs that provide access to detailed bank account information for personal financial management services.
