Certificates start `pending` and exempt nothing until verified. `country_code` and `state_code` say where the certificate holds — omit both for one valid everywhere, give only the country for one valid throughout it. `document_signed_id` takes the `signed_id` returned by `POST /api/v3/admin/files`. **Required scope:** `write_customers` (for API-key authentication). ## OpenAPI ````yaml /api-reference/admin.yaml post /api/v3/admin/companies/{company_id}/tax_exemption_certificates 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 login, logout, token refresh, and current user profile - name: Allowed Origins description: CORS allowlist for storefront and admin client origins - name: API Keys description: Secret and publishable API keys - name: Categories description: >- Hierarchical product categories — tree management, repositioning, and product assignments - name: Channels description: >- Sales channels, product publication across channels, and per-channel order routing rules - name: Custom Fields description: >- Custom field definitions for products, variants, customers, and other resources - name: Customer Groups description: >- Customer groups for segmenting customers (e.g. wholesale, VIP) used by pricing and promotions - name: Customers description: Customer profiles, addresses, credit cards, and store credits - name: Email Templates description: >- Customer email templates, the email layout and shared partials: drafts, previews, publishing and history - name: Exports description: Async CSV exports of admin resources - name: Files description: Uploading the files that product media, imports, logos and documents use - name: Fulfillments description: Order fulfillments — shipments, fulfill, cancel, resume, split - name: Gift Cards description: Gift cards and gift card batches - name: Imports description: >- Async CSV imports of admin resources, with per-row status and failed-row retry - name: Markets description: >- Markets — geographic groupings of countries used for pricing, tax, and fulfillment rules - name: Option Types description: >- Option types and option values used to build product variants (e.g. Size, Color) - name: Orders description: Orders, order items, applied gift cards, and applied store credits - name: Payment Methods description: Configured payment providers and their available types - name: Payments description: Order payments — list, capture, void - name: Pricing description: >- Prices and price lists for currency-, market-, and customer-group-specific pricing - name: Products description: >- Products, taxons/categories, product custom field values, and bulk product operations - name: Policies description: The store's legal documents — terms of service, privacy, returns, shipping - name: Reasons description: >- Merchant-owned vocabularies for why a return, claim, refund, cancellation or tax exemption happened - name: Promotions description: Promotions, promotion rules, promotion actions, and coupon codes - name: Refunds description: Order refunds - name: Settings description: Store-level settings — store profile, tags, and configuration - name: Staff description: Admin users, roles, and invitations to the store - name: Stock Locations description: Warehouses and physical fulfillment locations - name: Store Credits description: Prepaid customer balances across all customers, and each balance's ledger - name: Variants description: >- Product variants — the individual SKUs (size/color combinations) sold under a product - name: Webhooks description: Webhook endpoints and webhook delivery history paths: /api/v3/admin/companies/{company_id}/tax_exemption_certificates: parameters: - name: x-spree-api-key in: header required: true schema: type: string - name: Authorization in: header required: true schema: type: string - name: company_id in: path required: true schema: type: string post: tags: - Companies summary: Create a tax exemption certificate description: >- Records exemption evidence against a business.
