note: >-
  Shopify's testing story is unusually strong for agent work specifically, because one of its four
  environments needs no account at all. mock.shop answers a full Storefront API introspection
  anonymously — an agent can be writing working GraphQL against real Shopify schema before anyone
  signs up for anything. Test PAYMENT values are deliberately omitted below: Shopify documents its
  Bogus Gateway test card numbers on help.shopify.com, which returned 403 to this probe, and
  inventing a test card is not something this pipeline will do.

    "A store's worth of data" — a real Storefront API surface stocked with sample products, backed by
    a growing set of reference stores (apparel, skincare, candles, jewellery). No auth, no keys, no
    store. Shopify positions it explicitly at agents: "Point your agent at a real Shopify Storefront
    API."
  limits: Read-only sample catalog; no real orders, no merchant admin surface.
- name: Dev store
  type: full free environment
  auth_required: true
  account_required: 'Shopify Partner / Dev Dashboard account (free)'
  console: https://dev.shopify.com/dashboard/
  docs: https://shopify.dev/docs/storefronts/themes/tools/development-stores
  detail: >-
    A free, fully functional Shopify store for building and testing apps, themes and custom
    storefronts. Created from the Dev Dashboard by choosing store type "Dev" and a plan to emulate.
  test_data:
    available: true
    opt_in: 'Generate test data for store, at creation time'
    docs: https://shopify.dev/docs/storefronts/themes/tools/development-stores/generated-data
    detail: >-
      Shopify populates the store with the common commerce primitives and configurations needed to
      test an app, theme or custom storefront — including some Plus-specific features. Stores are
      empty by default; this is opt-in at creation.
  feature_previews:
    available: true
    docs: https://shopify.dev/docs/apps/build/stores/feature-previews
    detail: Test capabilities not yet available to all stores.
  protection: >-
    Dev stores are always password protected and the password page cannot be customized. The password
    can only be removed after transfer to a merchant or a switch to a paid plan.

  type: instant merchant-facing trial
  auth_required: false

  command: shopify store create preview
  docs: https://shopify.dev/docs/apps/build/ai-toolkit
  detail: >-
    Created from the CLI (or from a conversation with an agent) for a merchant who does not yet have
    a Shopify account. Can later be claimed and made real. This is the surface behind Shopify's
    "turn an idea into a store you can claim by having a conversation with ChatGPT, Claude, Lovable,
    Replit, Vercel (v0), Perplexity, Manus" positioning.
- name: unstable / release-candidate API versions
  type: version channel
  auth_required: true
  docs: https://shopify.dev/docs/api/usage/versioning
  detail: >-
    `unstable` is continuously updated with in-progress changes and is the early-testing channel; the
    release candidate for the next quarter publishes on the same day the current stable ships. Both
    are addressed by putting the version in the request URL — no separate host or key.
key_modes:
  note: >-
    Shopify does not use a test/live key prefix convention. The environment is the STORE, not the
    key: a dev store issues ordinary access tokens against ordinary endpoints, and its
    {store}.myshopify.com host is what marks it as non-production.
  test_key_prefix: null
  live_key_prefix: null
time_simulation:
  supported: false
  note: No test clock or time-travel facility is published, unlike a subscriptions-first payments API.
payment_testing:
  documented: true
  mechanism: Bogus Gateway (a test payment provider enabled on dev stores)
  values_recorded: false
  reason: >-
    The test card values live on help.shopify.com, which returned HTTP 403 to this probe. Values are
    not recorded rather than guessed.

fixtures_and_triggers:
  webhook_testing:
    mechanism: Shopify CLI + sample payloads published per topic
    detail: >-
      Every one of the 206 webhook topics has a published sample payload in the webhook reference —
      an unusually complete fixture set. See asyncapi/shopify-webhooks.yml.
