Include this in the `x-spree-token` header for guest access to that specific order. ## Response Format All responses are JSON. List endpoints return paginated responses with `data` and `meta` keys. ## Error Handling Errors return a consistent format: ```json { "error": { "code": "record_not_found", "message": "Product not found" } } ``` version: v3 servers: - url: http://{defaultHost} variables: defaultHost: default: localhost:3000 security: [] tags: - name: Authentication description: Customer authentication (login, logout, token refresh) - name: Product Catalog description: Products and categories - name: Carts description: Shopping cart management - name: Orders description: Order lookup - name: Customers description: Customer account, addresses, saved payment methods, and order history - name: Markets description: Markets, countries, currencies, and locales - name: Wishlists description: Customer wishlists - name: Policies description: Store policies (return policy, privacy policy, terms of service) - name: Digitals description: Digital product downloads paths: /api/v3/store/products/filters: get: tags: - Product Catalog summary: Get product filters description: > Returns available filters for products with their options and counts.
