notes: >-
  BMO's commercial developer portal publishes a free sandbox where developers
  experiment against simulated (non-production) test data with no fees, plus a
  pre-production environment that mirrors production before go-live. Concrete
  magic test values (test account numbers, sample tokens) are exposed inside the
  partner-gated API Explorer once an organization account is approved, so they
  are not reproduced here (no fabrication). Environments and their purpose are
  published on the portal and captured below.
environments:
- name: sandbox
  purpose: >-
    Free, self-serve experimentation against simulated test data; no fees, no
    real accounts. Used to build and test API calls before requesting
    production access.
  test_data: simulated / synthetic
  cost: free
- name: pre-production
  purpose: >-
    Higher-fidelity environment to validate an integration against
    production-like conditions before promotion to production.
- name: production
  purpose: Live environment against real BMO Online Banking for Business accounts.
access: >-
  Sandbox is available after registering on developer.bmo.com; production and
  pre-production require an approved BMO organization account and OAuth 2.0
  client credentials issued via the Authorize API.
