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/orders/{order_id}/fulfillments/{fulfillment_id}/labels/{id}: parameters: - name: order_id in: path description: Prefixed order ID required: true schema: type: string - name: fulfillment_id in: path description: Prefixed fulfillment ID required: true schema: type: string - name: id in: path description: Prefixed shipping label ID required: true schema: type: string get: tags: - Fulfillments summary: Show a shipping label description: One label on one of this seller's parcels, with the link to print it. parameters: - name: X-Spree-Seller-Id in: header required: true schema: type: string responses: '200': description: label found content: application/json: example: id: lbl_UkLWZg9DAJ source: uploaded status: purchased carrier: ups carrier_name: UPS service: Ground tracking_number: 1Z879E930346830008 currency: USD format: pdf external_id: null metadata: {} refunded_at: null created_at: '2026-01-15T12:00:00.000Z' updated_at: '2026-01-15T12:00:00.000Z' owner_id: ful_UkLWZg9DAJ owner_type: fulfillment cost: '7.25' integration_id: null file_pending: false download_url: >- /api/v3/seller/orders/or_UkLWZg9DAJ/fulfillments/ful_UkLWZg9DAJ/labels/lbl_UkLWZg9DAJ/download schema: $ref: '#/components/schemas/ShippingLabel' security: - bearer_auth: [] x-codeSamples: - lang: javascript label: Spree Seller SDK source: |- import { createSellerClient } from '@spree/seller-sdk' const client = createSellerClient({ baseUrl: 'https://your-store.com', jwtToken: 'eyJhbGciOi...', sellerId: 'sel_UkLWZg9DAJ', }) const label = await client.orders.fulfillments.labels.get( 'or_UkLWZg9DAJ', 'ful_UkLWZg9DAJ', 'lbl_UkLWZg9DAJ', ) components: schemas: ShippingLabel: type: object properties: id: type: string source: type: string enum: - purchased - uploaded status: anyOf: - type: string enum: - purchased - refund_requested - refunded - type: string description: The values listed are the built-in ones;
