aid: bank-of-montreal url: https://raw.githubusercontent.com/api-evangelist/bank-of-montreal/refs/heads/main/apis.yml name: BMO Financial Group kind: company description: >- BMO Financial Group (Bank of Montreal) is one of Canada's Big Six banks and a Schedule I domestic chartered bank, founded in Montreal in 1817 as Canada's oldest bank. It is a diversified North American financial-services provider serving personal, commercial, wealth, and capital-markets clients across Canada and the United States (where it operates as the separately chartered BMO Bank N.A.). BMO runs a first-party, bilingual (EN/FR) commercial developer portal at developer.bmo.com for Online Banking for Business customers, publishing OAuth 2.0-secured Account Information, Account Validation, Image Retrieval, Payment (domestic and international / embedded finance), Authorize, and Encryption APIs on an IBM API Connect platform with a free sandbox and pre-production environment. Documentation and OpenAPI/API Explorer specs sit behind an approved organization account, so the surface is partner-gated rather than openly downloadable. Canada has no operational open-banking mandate yet — the federal Consumer-Driven Banking framework (Budget 2024 / Fall Economic Statement 2024, overseen by the FCAC) is legislated but not live — so consumer data access today remains voluntary and largely aggregator-based (Flinks, Plaid), while BMO's own public program is a commercial treasury/ payments API offering. image: https://kinlane-images.s3.amazonaws.com/shared/apis-json/apis-json-logo.jpg tags: - Financial Services - Banking - Canada - Big Six - Commercial Banking - Payments - Treasury - Open Banking - Consumer-Driven Banking created: '2026-07-23' modified: '2026-07-23' specificationVersion: '0.19' apis: - aid: bank-of-montreal:bmo-account-information-api name: BMO Account Information API description: >- Real-time access to BMO Online Banking for Business account data — current balances; day-end, month-end and year-end balances; and transaction histories that can replace BAI files and other settlement reports — surfaced directly inside accounting and treasury-management systems. humanURL: https://developer.bmo.com/api/commercial/product baseURL: https://api.bmo.com tags: - Account Information - Balances - Transactions properties: - type: Documentation url: https://developer.bmo.com/api/commercial/faq - type: APIReference url: https://developer.bmo.com/api/commercial/product - aid: bank-of-montreal:bmo-account-validation-api name: BMO Account Validation API description: >- Validates third-party accounts before a transaction is created, reducing failed or misdirected payments.
