National Bank Consumer Data Access (Aggregator-Mediated)
National Bank of Canada exposes no public, self-serve first-party developer API. Consumer financial-data access is consent-based and aggregator-mediated: when a customer links a fintech app, National Bank redirects the customer to authenticate and grant consent, then shares data through a secure, FDX-aligned data feed. This access is delivered principally via Flinks (National Bank's ~80%-owned Montreal aggregator) through its Open Banking Environment (OBE), and also via Plaid. Fintechs onboard through the aggregator's accreditation process rather than a National Bank developer console. No National Bank OpenAPI/Swagger is publicly downloadable.
