When addresses change, the order state is reverted to address to ensure shipments are recalculated. ## OpenAPI ````yaml /api-reference/store.yaml patch /api/v3/store/carts/{id} openapi: 3.0.3 info: title: Store API contact: name: Spree Commerce url: https://spreecommerce.org email: hello@spreecommerce.org description: > Spree Store API v3 - Customer-facing storefront API for building headless commerce experiences. ## Authentication The Store API uses two authentication methods: ### API Key (Required) All requests must include a publishable API key in the `x-spree-api-key` header. ### JWT Bearer Token (For authenticated customers) After login, include the JWT token in the `Authorization: Bearer ` header. ### Order Token (For guest checkout) When creating an order, a `token` is returned. 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/carts/{id}: patch: tags: - Carts summary: Update a cart description: >- Updates cart info (email, addresses, customer note).
