Open Banking & API Integration Flashcards

What is the key distinction between 'open banking' and 'open finance'?

Answer: Open banking focuses on bank account and payment data while open finance extends to all financial products including insurance, investments, and pensions

Open finance extends open banking principles beyond bank accounts and payments to encompass all financial products—insurance, mortgages, investments, and pensions—creating a comprehensive consumer financial data ecosystem.

Which security specification is used for Financial-grade API (FAPI) profiles in open banking implementations?

Answer: OpenID Connect combined with FAPI security profiles

OpenID Connect with FAPI (Financial-grade API) security profiles provides the identity layer and enhanced security requirements—including strict token binding and request signing—needed for high-security open banking API implementations.

What is the function of an 'API gateway' in an open banking infrastructure?

Answer: A management layer that handles API traffic routing, security enforcement, rate limiting, and analytics between banks and third parties

An API gateway acts as the central intermediary that manages, secures, throttles, and monitors all API traffic in an open banking ecosystem, enforcing authentication policies and providing operational analytics.

What is the primary challenge preventing seamless interoperability in global open banking systems?

Answer: Regulatory and standards fragmentation, with different API specifications and compliance requirements across jurisdictions

The absence of globally unified API standards and harmonized regulatory frameworks creates fragmentation, making it difficult for fintech companies to build portable solutions that operate consistently across different countries.

What is 'Dynamic Client Registration' (DCR) in an open banking authorization context?

Answer: A mechanism allowing third-party providers to programmatically register as authorized API clients with an authorization server without manual provisioning

DCR enables Third Party Providers (TPPs) to automatically and securely register themselves as clients with Open Banking authorization servers, enabling scalable API onboarding without manual approval processes.

Which of the following best defines 'embedded finance' as enabled by open banking APIs?

Answer: The integration of financial services such as payments, lending, and insurance directly into non-financial products and platforms

Embedded finance refers to the seamless integration of financial services—payments, credit, insurance, savings—directly into non-financial platforms (e-commerce, ride-sharing, SaaS), made possible through open banking APIs.

What does 'API monetization' mean for banks participating in the open banking ecosystem?

Answer: Generating revenue by offering premium API products, data services, and infrastructure access to fintech companies and developers

API monetization enables banks to create new revenue streams by commercializing their API capabilities—offering premium data products, enhanced API tiers, and infrastructure-as-a-service to fintech companies building on their platforms.
