Endpoint: GET /api/v1/inventory

Full URL: https://api.spreetaileu.com/api/api/v1/inventory

Retrieve current inventory levels for your account.

Authentication-Based Access

• The inventory returned is automatically filtered based on your authenticated client
• No additional parameters needed - your JWT token determines which inventory you can see
• Each client has specific warehouse locations and SKU prefixes configured

Response Data

Returns comprehensive inventory information including:

• Total inventory count across all SKUs
• Number of unique SKUs
• Detailed per-SKU information:
  • SKU/Part Number
  • Physical dimensions (Height, Width, Depth)
  • Weight
  • Retail price
  • Current stock level
  • In Order Book (allocated to orders)
  • Available (free stock)
  • Last update timestamp and operation

Use Cases

• Monitor stock levels for reordering
• Check product availability
• Integrate with your inventory management system
• Generate stock reports

Pagination

This endpoint supports efficient pagination by passing parameters directly to Linnworks:

• Use page parameter to specify which page to retrieve (default: 1)
• Use page_size parameter to control items per page (default: 25, max: 200)
• Response includes pagination metadata (current_page, page_size, has_more, next_page)
• Each location indicates if more data is available via has_more field

SKU Filter (optional)

• Use the sku query parameter to fetch stock for specific SKUs only
• Comma-separated list of client SKUs, case-insensitive, max 50 per request
• Example: ?sku=ABC-123,XYZ-789
• When provided, the response adds requested_sku_count and not_found_skus (any SKUs that did not resolve for your client)
• When omitted, behavior is unchanged

Changed-Since Filter (optional)

• Use the last_modified query parameter to return only SKUs whose stock record was updated on or after a given moment
• Accepts a date (YYYY-MM-DD, start of that day UTC) or a full ISO timestamp (e.g. 2026-08-01T14:30:00Z)
• Compares against the same LastUpdateDate value returned per SKU, per warehouse location — a SKU updated recently at one location appears only under that location
• Treat it as "may have changed since": the stock record is touched by orders, deliveries and adjustments, but also by some administrative events — it never misses a change
• Filtering is applied per page, so pages can contain fewer than page_size entries (even zero) while has_more is still true — keep paging until has_more is false
• The applied value is echoed back as data.last_modified; malformed values return 400

Performance

• Typical response time: 2-5 seconds per request
• Pagination is handled by Linnworks API (very efficient)
• Recommended: Start with page_size=25-50 for best performance
