description: >-
  Narmi ships a dedicated sandbox environment for the Public API. The OpenAPI
  schema itself is served from the sandbox host, and the official TypeScript
  SDK's build tooling downloads it directly from there.
environments:
  - name: sandbox
    api_base_url: https://api.sandbox.narmi.dev/
    schema_url: https://online.sandbox.narmi.dev/v1/schema
    oauth_authorize: https://api.sandbox.narmi.dev/v2/oauth/authorize/
    oauth_token: https://api.sandbox.narmi.dev/v2/oauth/token/
    notes: >-
      Declared as the servers[] entry in the Public API OpenAPI. The SDK's
      `download-schema` npm script pulls the live schema from
      online.sandbox.narmi.dev/v1/schema to regenerate the client.
test_data:
  published: false
  notes: >-
    Narmi does not publish universal magic test values (test cards / test
    accounts) the way a card acquirer does — the Public API runs against a
    financial institution's own sandbox core data, provisioned per developer
    engagement. Sandbox credentials (OAuth client_id / client_secret and PKCE)
    are issued to onboarded institution developers rather than self-serve.
    No test values are asserted here to avoid fabrication.
