Open Banking FAQ

What is Open Banking?

Open Banking is a system that allows third-party financial service providers to access consumer banking data through APIs, with customer consent. Regulated by PSD2 in Europe and similar frameworks globally, Open Banking enables services like account aggregation, payment initiation, and financial comparison tools. It promotes competition and innovation in financial services.

What is an API aggregator?

An API aggregator (also called open banking platform or data aggregator) is a company that provides unified access to multiple banks' APIs through a single integration. Instead of connecting to hundreds of banks individually, developers integrate once with an aggregator like Plaid, Tink, or TrueLayer to access thousands of financial institutions. This simplifies building financial apps.

What is PSD2?

PSD2 (Payment Services Directive 2) is an EU regulation that requires banks to provide API access to authorized third parties. Implemented in 2019, PSD2 created the legal framework for Open Banking in Europe. It introduced two new types of regulated providers: AISPs (Account Information Service Providers) for data access and PISPs (Payment Initiation Service Providers) for payments.

Is Open Banking safe?

Yes, Open Banking is designed with security as a core principle. All third-party providers must be licensed and regulated by financial authorities (FCA in UK, national regulators in EU). Data is encrypted, you authenticate directly with your bank, and you control which apps access your data. You can revoke access at any time. Banks never share your login credentials with third parties.
