Unknown codes are silently dropped. - `supported_locales` accepts an array of locale codes; the `default_locale` is always implicitly included. - Setting `default: true` automatically demotes the previous default market in the store. **Required scope:** `write_settings` (for API-key authentication). ## OpenAPI ````yaml /api-reference/admin.yaml post /api/v3/admin/markets openapi: 3.0.3 info: title: Admin API contact: name: Spree Commerce url: https://spreecommerce.org email: hello@spreecommerce.org description: > Spree Admin API v3 - Administrative API for managing products, orders, and store settings. ## Authentication The Admin API requires a secret API key passed in the `x-spree-api-key` header. Secret API keys can be generated in the Spree admin dashboard. ## Response Format All responses are JSON. List endpoints return paginated responses with `data` and `meta` keys. Single resource endpoints return a flat JSON object. ## Resource IDs Every resource is identified by an opaque string ID (e.g. `prod_86Rf07xd4z`, `variant_k5nR8xLq`, `or_UkLWZg9DAJ`). Use these IDs everywhere — URL paths, request bodies, and Ransack filters all accept them directly. ## Error Handling Errors return a consistent format: ```json { "error": { "code": "validation_error", "message": "Validation failed", "details": { "name": ["can't be blank"] } } } ``` version: v3 servers: - url: http://{defaultHost} variables: defaultHost: default: localhost:3000 security: [] tags: - name: Authentication description: Admin user authentication - name: Product Catalog description: Products, variants, and option types - name: Orders description: >- Order management — orders, items, payments, fulfillments, refunds, gift cards, store credits - name: Customers description: Customer management — profiles, addresses, store credits, credit cards - name: Configuration description: Store configuration — payment methods, tag autocomplete paths: /api/v3/admin/markets: post: tags: - Pricing summary: Create a market description: >- Creates a new market for the current store. - `country_isos` accepts 2-letter ISO country codes (e.g. `["DE", "FR"]`); the market must contain at least one country.
