summary: >-
  Fyndiq provides a self-contained sandbox environment in which merchants can
  prototype and test their integration before going live. It mirrors the
  production resource surface at a separate base URL, with separate credentials.
environments:
  - name: sandbox
    base_url: https://merchants-api.sandbox.fyndiq.se/api/v1/
    resources:
      articles: https://merchants-api.sandbox.fyndiq.se/api/v1/articles
      orders: https://merchants-api.sandbox.fyndiq.se/api/v1/orders/
  - name: live
    base_url: https://merchants-api.fyndiq.se/api/v1/
credentials:
  mechanism: HTTP Basic (merchantID:token)
  provisioning: Sandbox credentials are provided by Fyndiq upon request.
  note: >-
    When migrating from sandbox to production you must change both the base URLs
    and the credentials in your code.
test_tooling:
  - name: Create a test order
    operation: createTestOrder
    detail: >-
      POST /orders/ creates a test order in the sandbox so merchants can exercise
      the order-retrieval and fulfilment flow. This endpoint is NOT available in
      production. Response time can vary.
test_values:
  documented: false
  note: >-
    Fyndiq does not publish magic/fixed test identifiers or test card numbers
    (the marketplace handles payments; merchants never touch card data). Test
    articles and orders are created live in the sandbox via the API.
