Infor M3 to Linnworks integration — real-time, two-way sync

Yes. Stacksync provides a managed, real-time two-way integration between Infor M3 and Linnworks: authenticate both systems, choose the objects to sync (such as Infor M3's Inventory Balances and Invoices), map fields visually, and changes propagate both ways in milliseconds — no code required.

On the Infor M3 side: Inventory Balances, Invoices, Warehouses, Price Lists, plus custom fields where Infor M3 exposes them. On the Linnworks side: Locations, Purchase Orders, Suppliers, Channel Listings. 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 Infor M3 and Linnworks: Two-tier roll-up; Migration in parallel; Shared master data. Where subsidiaries run one system and headquarters runs the other, shared records and transactions flow up continuously, so consolidation starts from live data.

Infor M3: REST API (M3 API programs exposed through the Infor ION API gateway). Authentication: OAuth 2.0 via Infor OS / ION API authorization. Linnworks: REST API. Authentication: Application credentials and an install token exchanged for a session token. Stacksync manages authentication, retries, and rate limits on both sides.

Infor M3: Infor ION can publish standard Business Object Documents (for example sales orders and item master changes) as events for downstream consumers, giving an event-based alternative to polling once configured in ION. Linnworks: Orders are modeled in two populations, open orders and processed orders, and syncs typically treat processing as the state transition that moves a record between them. Stacksync's field mapping accounts for these differences between Infor M3 and Linnworks without custom code.
