When the job is complete, the response includes a temporary signed download URL for the ZIP bundle and an ``expires_at`` timestamp. The endpoint is rate limited at the global API key tier. ## OpenAPI ````yaml /openapi/openapi-products.json get /products/api/v1/qr/bulk/{task_id}/ openapi: 3.1.0 info: title: Products API version: 1.0.0 description: > Look up, claim, and browse GTINs in the Closient product repository. ## Authentication All endpoints require an API key passed via the `X-API-Key` HTTP header, unless otherwise noted. ``` X-API-Key: csb__ ``` Generate API keys in **Settings > API Keys** in your dashboard, or via the Account API. Session-based (cookie) authentication is also accepted for browser-based access. ## Rate Limits | Tier | Requests / minute | Requests / day | |-------------|-------------------|----------------| | Default | 300 | 10,000 | | Custom | Contact us | Contact us | Rate-limit headers are included on every response so callers can self-throttle without hitting our 429s ("informed governor"): - `RateLimit-Policy` — every active window, e.g. `300;w=60, 10000;w=86400` - `RateLimit-Limit` — quota for the **most-restrictive** currently-active window - `RateLimit-Remaining` — requests left in that window - `RateLimit-Reset` — seconds until that window resets (relative; clock-skew safe) Legacy `X-RateLimit-*` aliases are also emitted for back-compat. `X-RateLimit-Reset` keeps the absolute Unix-timestamp shape to avoid breaking existing consumers. When rate-limited, you receive `429 Too Many Requests` with a `retry_after_seconds` field in the error envelope and a `Retry-After` header. ## Pagination List endpoints return paginated results in this envelope: ```json { "data": [...], "pagination": { "page": 1, "page_size": 25, "total_count": 342, "total_pages": 14, "has_next": true, "has_previous": false } } ``` Use `?page=2&page_size=50` query parameters. Maximum page size is 100. ## Error Responses All errors conform to [RFC 9457 Problem Details](https://www.rfc-editor.org/rfc/rfc9457) with `Content-Type: application/problem+json`: ```json { "type": "https://closient.com/docs/errors/not_found", "title": "Not Found", "status": 404, "detail": "The requested resource was not found.", "error_code": "not_found", "retryable": false, "timestamp": "2026-03-31T12:00:00+00:00" } ``` Common error codes: `unauthorized` (401), `forbidden` (403), `not_found` (404), `validation_error` (422), `rate_limited` (429), `internal_error` (500). termsOfService: https://www.closient.com/terms/ servers: - url: https://www.closient.com security: [] tags: - name: Products description: Look up, claim, and browse products and trade items. - name: Product Group description: Manage GDSN packaging hierarchy relationships. - name: Import description: Bulk import products from CSV files. - name: QR description: Generate QR codes encoding GS1 Digital Link URLs. - name: Codes description: Generate GS1 DataMatrix and 1D barcodes (EAN/UPC/ITF-14/Code128). - name: Digital Link description: >- Parse GS1 Digital Link URIs into structured AIs (GTIN, lot, expiry, serial). - name: Labels description: >- Bulk label-export jobs: ZIPs of QR / DataMatrix / 1D symbols and multi-up sheet PDFs, async via Celery with status polling. externalDocs: description: Closient Documentation url: https://docs.closient.com paths: /products/api/v1/qr/bulk/{task_id}/: get: tags: - QR summary: Poll a bulk QR generation task description: >- Returns the status of a previously queued bulk QR job.
