note: >-
  The Bridge Open Banking program run by East West Bank, East West Bancorp's banking
  subsidiary, publishes a sandbox. No concrete test values — account numbers, test
  credentials, magic identifiers — appear anywhere on the anonymous surface; they are
  provisioned per application after sign-in and sales onboarding, so none are reproduced
  here. This captures the sandbox model the provider documents, verbatim where quoted.
sandbox:
  available: true
  self_serve: false
  gate: >-
    Portal sign-up is free and self-serve, but sandbox and production access require contact
    with an East West Bank GTS sales consultant, who supplies pricing, the onboarding
    documents, the client certificate and the access credentials.
  test_vs_live: >-
    Three tiers, not two: the anonymous/registered portal (in-browser "try it" against
    documentation prompts, no certificate needed), a sandbox connected to a live banking
    environment with bank-supplied test accounts and live transfers, and production.
  test_data: >-
    "We supply test data, including live test accounts, in our sandbox environment." Test
    accounts and test payments are provisioned to the developer's application rather than
    published.
  in_browser_testing: >-
    "Our documentation pages allow in-browser testing on the Bridge Open Banking portal.
    Simply pre-populate the data using the documentation prompts and insert missing fields
    from your application or access token information."
  client_certificate_required: true
  client_certificate_note: >-
    A certificate is required for connectivity to both sandbox and production; no certificate
    is needed for portal access. Certificates are issued by GTS during onboarding.
