  The GSMA runs two sandbox surfaces, one per programme. Neither publishes magic test values
  (test numbers, test cards, fixture identifiers) on a public page — the Open Gateway sandbox is
  behind a GitHub sign-in and the Mobile Money simulator host declared in the specification does
  not currently resolve. Nothing below is invented; where a value is not published this file says so.
sandboxes:
- name: GSMA Open Gateway API Sandbox
  url: https://open-gateway.gsma.com/sandbox
  status: 200
  gated: true
  gate: Sign in with GitHub
  purpose: >-
    Pre-production playground for CAMARA / Open Gateway APIs before moving to an operator or an
    aggregator. The GSMA operates no production endpoints, so the sandbox is the only GSMA-hosted
    credential surface.
  auth_flows_supported:
  - client_credentials
  - CIBA (Client Initiated Backchannel Authentication)
  - authorization_code
  - jwt_bearer
  test_values_published: false
  note: >-
    Portal copy names the four supported authorization flows. Test identities, test phone numbers
    and sandbox client credentials are issued behind the GitHub sign-in and are not published
    anonymously.
