summary: >-
  BNY publishes non-production testing environments for its Developer
  Marketplace APIs. Many Treasury Services and other API families ship with a
  QA / testing environment seeded with realistic test data so integrators can
  evaluate, prototype, and build before production. Access to both QA and
  Production credentials is gated behind the BNY onboarding process and Nexen
  single sign-on: developers subscribe to an API in the Marketplace, obtain
  credentials for the QA and Production environments, and must complete BNY
  onboarding for production access. No test card numbers, magic test
  identifiers, or fixed sandbox tokens are published on the public surface —
  those values live behind the authenticated Marketplace.

    Production access to the API Marketplace and the APIs requires completing
    the BNY onboarding process; QA and Production credentials are issued per
    subscribed API.
notes: >-
  Published test values (identifiers, accounts, fixtures) are not exposed on the
  anonymous public surface — the API reference, specs, and sandbox are behind
  Nexen SSO. This artifact records the documented environment structure only;
  no test values were fabricated.
