Open Banking Specifics in Portugal

# General Specifics

Most Portuguese banks implement Open Banking through the SIBS API Market platform, which serves as the primary Open Banking infrastructure in Portugal. SIBS (Sociedade Interbancária de Serviços) operates this platform as a centralized API marketplace that connects banks, fintechs, and other financial service providers. The platform provides standardized PSD2-compliant APIs for account information services, payment initiation services, and funds confirmation services.

The SIBS API Market offers a unified interface for Third Party Providers (TPPs) and provides developer documentation and sandbox environments for testing. The centralized approach helps to improve consistency across Portuguese banks' Open Banking implementations, though banks' APIs behave with some specifics and also authentication and consent handling have variations.

# Authentication flows and SCA

Portuguese banks predominantly use redirect-based flows for Open Banking authentication, following PSD2 requirements. Users are redirected to their bank's authentication interface where they log in using their online banking credentials. Strong Customer Authentication (SCA) is typically performed through the banks' mobile banking applications using biometric authentication (fingerprint, face recognition) or PIN-based verification.

# Major Banks (ASPSPs)

The most widely used Portuguese ASPSPs, in order of market significance, are:

# Payment Specifics

Portuguese banks support SEPA Credit Transfers (SCT) in EUR (Euro) through their Open Banking APIs. As Portugal is part of the eurozone and SEPA, all major banks provide comprehensive support for euro-denominated payments within the Single Euro Payments Area.

SEPA Instant Credit Transfers (SCT Inst) are widely supported by Portuguese banks, enabling real-time euro transfers that are processed within seconds and available 24/7/365. This instant payment capability is particularly well-developed in Portugal, with most major banks offering this service through their Open Banking interfaces.
