- openapi/ (servers[] in all five OpenAPI 3.0.1 documents)

summary: >-
  PPL runs three fully separated environments and the sandbox is real — it is the ONLY host any of
  the five published OpenAPI documents declares in servers[]. But it is not self-serve: there are
  no published test credentials, no test keys, no magic test identifiers and no seeded test data.
  Access to the sandbox requires the same three-stage market onboarding as production, including
  its own Azure AD guesting and its own registered X.509 certificate.

test_vs_live_separation:
  mechanism: separate hosts + separate Azure AD tenants + separate client certificates
  key_prefixes: null
  mode_switch: none — there is no live/test flag on a single credential
  rules:
  - Accounts must be guested into ONE environment at a time (Sand, PreProd or Prod); each environment requires separate guesting.
  - '"A different X.509 certificate should be used for each API Gateway (Sand, PreProd and Prod)."'
  - TenantId in the application configuration is environment specific.

      The collections themselves are freely downloadable; running them still requires an onboarded
      Entra ID identity and a registered certificate.
  test_harness:
    status: planned
    source: https://developer.pplnextgen.com/Get-Started/RoadMap
    statements:
    - Registration and Onboarding describes a third stage, "Registering to use a Test Harness", and states the portal will eventually support "testing tools (eg POSTMAN) and test source code against a sandbox environment".
    - The roadmap lists a hosted "Intelligent Test Harness and Test Client" and a hosted "Instrumentation & Diagnostics" service as mid-term deliverables.

  note: >-
    PPL publishes no test card numbers, test UMRs, test placement identifiers, seeded broker or
    carrier organisations, or reserved test email addresses. Nothing is invented here. Test data in
    the Sand/JIT2 environment is agreed bilaterally as part of joint integration testing between
    the onboarding organisation, PPL and LIMOSS.
