7 QUESTIONS, BRIEFLY ANSWERED

Frequently asked questions about FIDA API Architecture and Security

What API security standards does the FIDA regulation mandate?

The FIDA proposal names no protocol at all. Article 10 obliges the Financial Data Sharing Schemes to agree common standards for customer data and for the technical interfaces, so the concrete specification is set in the scheme and in delegated acts rather than in the regulation itself. The standards the market is converging on are OAuth 2.0 with PKCE (Proof Key for Code Exchange), OpenID Connect, TLS 1.3, Strong Customer Authentication (SCA) and ISO‑20022 compliant data formats. What the proposal does contain is the duty to make customer data available continuously, as well as the interplay with operational resilience under DORA.

What is a zero-trust model for FIDA APIs?

A zero-trust model for FIDA APIs means no API access is automatically trusted. Every request is authenticated and authorized regardless of network location. This includes token validation on every call, micro-segmentation, continuous monitoring and defense-in-depth strategies with multiple security layers.

How does FIDA API architecture differ from PSD2 interfaces?

FIDA goes far beyond PSD2: instead of just payment data, FIDA covers all financial products including loans, insurance, pensions and prospectively crypto assets. The API architecture must support Financial Data Sharing Schemes (FDSS), provide granular consent management and scale with significantly more data types and actors.

What role does an API gateway play in FIDA compliance?

The API gateway is the central security layer for FIDA-compliant interfaces. It handles rate limiting, token validation, request routing, logging for audit trails and policy enforcement. For FIDA, the gateway must additionally perform consent checks and ensure only authorized FISPs access approved data.

How long does implementing a FIDA-compliant API architecture take?

Depending on the starting point, implementation takes 6 to 18 months. Banks with existing PSD2 infrastructure can migrate faster. Insurers and asset managers without API experience need more time. The Council negotiating position provides phased deadlines of 24, 36 and 48 months after entry into force per data category.

What encryption standards apply to FIDA APIs?

For FIDA APIs, end-to-end encryption with TLS 1.3 for data in transit and AES‑256 for data at rest is the market standard; the binding specification comes from the respective scheme. Tokenization provides additional protection for sensitive financial data. Post-quantum cryptography will become relevant as FIDA requires long-term data security.

How are FIDA and DORA connected regarding API security?

FIDA and DORA complement each other: DORA defines operational resilience for ICT systems including APIs. FIDA builds on this framework and additionally requires API-specific security such as consent dashboards, third-party access controls and incident response plans. Banks should implement both regulations together.
