Linnworks to Snapfulfil integration — real-time, two-way sync

Yes. Stacksync provides a managed, real-time two-way integration between Linnworks and Snapfulfil: authenticate both systems, choose the objects to sync (such as Linnworks's Shipping Services and Open Orders), map fields visually, and changes propagate both ways in milliseconds — no code required.

On the Linnworks side: Processed Orders, Stock Items, Stock Levels, Locations, plus custom fields where Linnworks exposes them. On the Snapfulfil side: Items (SKUs), Inventory balances, Shipments, Warehouse locations. Stacksync auto-detects both schemas and converts types between the two systems.

Yes. Each object mapping can be bidirectional or restricted to a single direction (both systems accept writes). Read-only mirrors, one-way pushes, and full two-way sync can be mixed in the same integration.

Common patterns for Linnworks and Snapfulfil: Shared master data; Split by function; Two-tier roll-up. Where both systems keep records of the same customers, suppliers, or organizations, a correction in either updates the other.

Linnworks: REST API. Authentication: Application credentials and an install token exchanged for a session token. Snapfulfil: REST-style web service API. Authentication: API credentials issued for the warehouse instance. Stacksync manages authentication, retries, and rate limits on both sides.

Linnworks: The Linnworks API uses a token-exchange model: application credentials plus a per-account install token are exchanged for a session token that authorizes subsequent calls. Snapfulfil: Its data model follows the warehouse order lifecycle (receive, putaway, pick, pack, ship), so integrations center on orders, stock, and shipments. Stacksync's field mapping accounts for these differences between Linnworks and Snapfulfil without custom code.
