aid: m-t-bank url: https://raw.githubusercontent.com/api-evangelist/m-t-bank/refs/heads/main/apis.yml name: M&T Bank kind: company description: >- M&T Bank is a US super-regional bank holding company (M&T Bank Corporation, NYSE: MTB) headquartered in Buffalo, New York, operating through its national bank subsidiary Manufacturers and Traders Trust Company. With roughly $200 billion in assets it is one of the twenty largest US commercial banks, serving consumers, businesses, and institutional clients across the eastern United States, and it owns Wilmington Trust, its custody, fund-administration, and wealth arm. Unlike UK/AU open banking there is no single mandated contract in the US, so M&T's public API posture is split: it runs a real first-party Developer Portal / "API Store" at developer.mtb.com for institutional and wholesale clients (Banking & Treasury plus Wilmington Trust Custody APIs), gated behind Microsoft Entra login and Azure API Management subscription keys with per-product OpenAPI reference available only after authentication. Consumer-permissioned account data is shared through aggregators (Plaid) rather than a public first-party consumer API. No public FDX conformance or CFPB Section 1033 data-access API is documented on the portal at review time. image: https://kinlane-images.s3.amazonaws.com/shared/apis-json/apis-json-logo.jpg tags: - Financial Services - Banking - United States - Super-Regional Bank - Treasury Management - Payments - Custody - Fund Accounting - Open Finance - Data Aggregation created: '2026-07-23' modified: '2026-07-23' specificationVersion: '0.19' apis: - aid: m-t-bank:payment-initiation name: Payment Initiation API description: >- Institutional payment initiation product listed in M&T's Banking and Treasury API group on the developer portal.
