Omit `mappings` to accept the auto-assigned ones from the create response. Returns 422 when a required field is left unmapped (`details.missing_required_fields`). ## OpenAPI ````yaml /api-reference/seller.yaml patch /api/v3/seller/imports/{id}/complete_mapping openapi: 3.0.3 info: title: Seller API contact: name: Spree Commerce url: https://spreecommerce.org email: hello@spreecommerce.org description: | Spree Seller API v3 - the marketplace seller panel, where a seller runs their own shop inside someone else's marketplace. This is a branch of its own, not a narrowing of the Admin API. Every endpoint is scoped server-side to the seller the request acts as, which is what makes cross-seller access impossible by construction rather than by rule. Sellers never call the Admin API. ## Authentication Sign in at `POST /api/v3/seller/auth/login` and send the returned JWT as `Authorization: Bearer `. The token carries a `seller_api` audience — a token minted for the storefront or the back office is not accepted here, and vice versa. There is deliberately **no secret API key** for this branch: a credential that could act as a seller without a seller signing in is exactly what the separate audience exists to prevent. ### Choosing a seller A user may run more than one seller. Login returns the list; send the chosen seller's ID in the `X-Spree-Seller-Id` header on every authenticated request. The store is derived from the seller — never sent — so no header can widen what a seller reaches. A request that names no seller the caller belongs to is rejected with `403`. ## 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": "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: Seller sign-in, token refresh, logout, and invitation acceptance - name: Account description: The signed-in user, the sellers they may act for, and what they may do - name: Countries description: Country and state reference data for the panel's address forms - name: Delivery Methods description: >- The seller's own ways to ship, and the marketplace methods shared with them - name: Delivery Profiles description: >- The marketplace's delivery vocabulary — what kind of goods a product is, which decides how it ships - name: Delivery Zones description: >- The marketplace's destinations, for narrowing where a seller's own method ships - name: Onboarding description: >- The marketplace checklist a seller completes before admission, and what they submit against it - name: Policies description: The seller's own legal documents, as the marketplace asks them to publish - name: Product Types description: The types a seller may list a product against, and what each adds - name: Products description: The seller's own catalog - name: Profile description: >- The seller's own record — presentation, contact details, addresses, and tax registration - name: Stock Locations description: Where the seller keeps stock, and so where their returns are sent - name: Team description: Who runs this seller, and the invitations nobody has accepted yet - name: Files description: Uploading the files a profile, a submission or an import uses paths: /api/v3/seller/imports/{id}/complete_mapping: parameters: - name: id in: path required: true description: Import prefixed ID schema: type: string patch: tags: - Imports summary: Complete mapping and start processing description: > Applies the submitted column mappings, then starts row processing.
