description: >-
  World-Check One offers a dedicated Pilot environment for developing and
  verifying an integration before promotion to Production. Pilot and Production
  are separate accounts with separate API credentials; credentials are
  provisioned by the LSEG account team (they cannot be self-served). No magic
  test identifiers or fixture data are published - the Pilot account screens
  against real World-Check data under a non-production entitlement.
environments:
  - name: pilot
    purpose: Development and basic testing before go-live
    api_v2_host: https://api-worldcheck.refinitiv.com/v2
    api_v3_host: https://api.risk.lseg.com/screening/v3/
    credentials: Separate pilot API key/secret (HMAC) or service-account (OAuth 2.0), issued by the LSEG account team
  - name: production
    purpose: Live screening
    api_v2_host: https://api-worldcheck.refinitiv.com/v2

    credentials: Separate production credentials
test_guidance:
  smoke_test: >-
    The quick start recommends calling GET /groups first to verify credentials -
    a 200 response returning your accessible groups confirms authentication works.
  postman: >-
    An official Postman collection (Case Management and Audit v3) plus a Postman
    environment file with all required variables is published on the quick-start
    page (sign-in required to download).
notes: >-
  Pilot and production share the same hostnames and URL structure; only the
  credentials and entitlements differ.
