The key resolves to a supplier contact; all reads and writes are tenant-scoped to that contact's supplier facility/company. Missing or invalid keys are answered with 401. ## Rate limiting 10 requests per 20-second window per API key. Requests beyond that are answered with 429 and the standard error envelope. (A few endpoints, noted in their descriptions, are not rate-limited.) ## Response envelope Single entity: `{"type": "", "data": {...}, "status": "ok"}`. Lists: `{"type": "", "data": [...], "count": , "status": "ok"}`. count_by endpoints return the integer count in `data`. The `type` label is hard-coded on some endpoints (e.g. "WorkOrderNotes", "pingpong") and derived via Scala reflection on generic CRUD endpoints, where it may appear as the fully qualified server class name - treat it as informational. Errors: `{"message": "...", "type": "", "status": "error", "traceId": "..."}` with HTTP 400 (bad input, and also permission-denied reads/writes), 401 (missing/invalid key), 404 (not found), 429 (rate limit). ## Pagination List endpoints accept `offset`, `limit` (default 10, max 25 - the supplier locations list caps at 10), `sort_by` and `order` (`asc`|`desc`), plus entity-specific query-string filters on indexed columns. ## Data masking For third-party suppliers (keys whose supplier company is not a buyer's internal service team), work order, location and invoice responses are masked: buyer-private fields are blanked before the response is returned. ## Date formats Date-time fields serialize as strings in one of two shapes depending on the underlying type: ISO 8601 with offset (e.g. `2026-08-14T13:05:22.000-07:00`) for most timestamps, or `yyyy-MM-dd HH:mm:ss.S` (space-separated, no offset) for database timestamp fields. Plain dates are `yyyy-MM-dd`. When sending date-times, ISO 8601 is accepted. ## Required headers Every request must carry BOTH `X-API-KEY` (your API key) and `OW-KEY` (the OpenWrench shared secret issued with it). Requests missing either return 401. servers: - url: https://api.useopenwrench.com/api/external security: - ApiKeyAuth: [] OwKeyAuth: [] tags: - name: Ping - name: Buyer Companies - name: Locations - name: Regions - name: Asset Types - name: Assets - name: Asset Labels description: Read the asset label catalog and replace the labels applied to an asset. - name: Work Orders - name: Work Order Labels description: >- Read the work order label catalog visible to your key and replace the labels applied to a work order. - name: Service Calls - name: WrenchMode description: Read-only WrenchMode work logs and technician time analytics - name: Proposals - name: Invoices - name: Files - name: Purchase Requests - name: Purchase Orders - name: Purchase Order Receipts - name: Parts - name: Equipment Types - name: Stock Location Inventory - name: Vendors - name: Users paths: /v1/supplier/inventory/purchase_order_receipts/{id}: get: tags: - Purchase Order Receipts summary: Get a purchase order receipt description: Retrieves one purchase-order receipt by id, subject to read permission. operationId: getPurchaseOrderReceipt parameters: - name: id in: path required: true schema: type: integer format: int64 description: Receipt id responses: '200': description: Successful response content: application/json: schema: $ref: '#/components/schemas/SupplierPurchaseOrderReceiptResponse' '400': description: >- Bad input, validation failure, or the API key's contact could not be resolved content: application/json: schema: $ref: '#/components/schemas/Error' '401': description: Missing or invalid X-API-KEY content: application/json: schema: $ref: '#/components/schemas/Error' '404': description: Entity not found (or not visible to this API key) content: application/json: schema: $ref: '#/components/schemas/Error' '429': description: Rate limit exceeded (10 requests per 20-second window) content: application/json: schema: $ref: '#/components/schemas/Error' components: schemas: SupplierPurchaseOrderReceiptResponse: type: object properties: type: type: string description: >- Entity type label, e.g. "SupplierPurchaseOrderReceipt".
