Coilinx Public API

Use the Coilinx Public API to synchronize inventory, material types, locations, and operational changes with an ERP, WMS, BI platform, or internal service.

API access and webhook management require a Coilinx Pro or Enterprise plan. Documentation is public so your implementation partners can build without needing a Coilinx user account.

Base URL

https://api.spoolrule.com

All inventory endpoints are read-only in v1. Every request requires a company-scoped API key:

curl "https://api.spoolrule.com/inventory/items?limit=100" \
  --header "Authorization: Bearer clx_live_key_your_key.secret"

Available resources

• Items — current inventory, measurements, checkout state, and timestamps.
• Material types — dimensions, density, spool weight, and pricing metadata.
• Locations — warehouses used to organize inventory.
• Webhooks — signed notifications for item and configuration changes.

Recommended integration pattern

1. Perform an initial paginated pull of items, material types, and locations.
2. Store Coilinx IDs as stable external identifiers.
3. Subscribe to webhook events.
4. When a webhook arrives, verify its signature and enqueue it internally.
5. Fetch the affected resource from the API to reconcile current state.
