Why teams connect Channelengine and Linnworks
Keep the storefront in step with the back office: Channelengine and Linnworks share products, inventory, and orders in real time, in both directions.
Channelengine runs the storefront and takes the orders; Linnworks owns the item master, the stock on hand, and the finance behind every transaction. The two overlap wherever the same products, customers, and sales matter to both — and when re-keying or an overnight batch is what connects them, the store oversells items it can't ship, quotes prices finance never set, or leaves buyers waiting on status that already changed.
Stacksync syncs Orders, Products (product content), Offers (price and stock), Shipments in Channelengine with Shipping Services, Open Orders, Processed Orders, Stock Items in Linnworks field by field, in real time, and in both directions. You decide which system owns which fields — stock and pricing from Linnworks, order and customer detail from Channelengine — and Stacksync keeps every copy consistent and resolves conflicts by rules you set.
Common use cases
- 01 Pull new marketplace orders with GET /v2/orders/new into an ERP or OMS and acknowledge them so fulfillment runs from the system of record.
- 02 Write Shipments with tracking back to ChannelEngine when the warehouse or ERP marks an order shipped, so each marketplace notifies the buyer.
- 03 Sync product and listing data with a PIM so channel listings stay aligned with the catalog
- 04 Push customer and order data to a CRM or marketing platform for post-purchase campaigns
Common sync patterns
One customer master
Where both systems keep customer records, a correction in either propagates to the other, ending dual maintenance.
Where Linnworks is the inventory system of record: stock stays accurate
Available quantities from Linnworks publish to Channelengine, so the store shows what can actually ship and stops overselling.
New orders reach the back office
An order captured in Channelengine creates the matching record in Linnworks with customer, line items, and totals, so fulfillment and invoicing start without re-entry.
What you can sync between Channelengine and Linnworks
Representative objects on each side — any object or custom field can map to any target. Schemas are auto-detected; types are converted between the two systems.
| Channelengine objects | Linnworks objects | How this pairing syncs | |
|---|---|---|---|
| Products (product content) Catalog records created and updated via POST /v2/products and deactivated via DELETE; use a parent/child variant model where the parent is a non-purchasable blueprint. Written into ChannelEngine from a PIM, ERP, or database. | Returns & Refunds Post-sale records flow to finance and support systems. | Products (product content) is specific to Channelengine and Returns & Refunds to Linnworks — each maps to any object or custom field on the other side. | |
| Offers (price and stock) Price and stock updates via PUT /v2/offer/stock and the offers endpoints; separate from product content so fast-changing stock can be pushed often, and supports bulk updates across stock locations. | Shipping Services Carrier and service definitions support label and tracking data in order syncs. | Offers (price and stock) is specific to Channelengine and Shipping Services to Linnworks — each maps to any object or custom field on the other side. | |
| Shipments Fulfillment records; write with POST /v2/shipments to mark an order shipped with tracking, read with GET /v2/shipments. Pushed back from a warehouse or ERP so marketplaces update the buyer. | Open Orders Unshipped orders aggregated from sales channels sync into ERPs and fulfillment systems. | Shipments is specific to Channelengine and Open Orders to Linnworks — each maps to any object or custom field on the other side. | |
| Returns Marketplace- and merchant-initiated returns; read via GET /v2/returns and created with POST /v2/returns. Synced two-way so customer-service and finance systems reconcile with the ERP. | Processed Orders Completed orders feed accounting and warehouse-based margin reporting. | Returns is specific to Channelengine and Processed Orders to Linnworks — each maps to any object or custom field on the other side. | |
| Cancellations Order cancellations; create with POST /v2/cancellations and read with GET /v2/cancellations. Written when stock is unavailable and read back for reconciliation. | Stock Items SKU records keep product data aligned with ERPs and PIMs. | Cancellations is specific to Channelengine and Stock Items to Linnworks — each maps to any object or custom field on the other side. | |
| Backorders Records marking part of an order as temporarily out of stock; create with POST /v2/backorders and read with GET /v2/backorders by merchant reference or since a date. | Stock Levels Per-location quantities sync outward so channels and planning tools reflect current availability. | Backorders is specific to Channelengine and Stock Levels to Linnworks — each maps to any object or custom field on the other side. |
How changes propagate between Channelengine and Linnworks
Each direction of the sync is driven by what the source system can signal and what the destination accepts — detection, delivery, and expected latency below.
Channelengine Linnworks Sub-second propagation
DetectionChannelengine notifies Stacksync of record changes through webhook events. Webhooks fire on order creation and on return and shipment/cancellation changes.
DeliveryEach detected change is written to Linnworks through its API, with automatic retries and rate-limit backoff.
Linnworks Channelengine Interval-based propagation
DetectionStacksync polls Linnworks for changes on an incremental schedule, reading only records changed since the previous pass. Polling on order and stock endpoints.
DeliveryEach detected change is written to Channelengine through its API, with automatic retries and rate-limit backoff.
Rate-limit considerations
- Channelengine: Rate limits are per endpoint and returned in headers: x-rate-limit-limit (interval length in minutes), x-rate-limit-remaining, and retry-after (seconds to wait); e.g. POST /v2/supportorder allows 3 calls per minute.
- Linnworks: Per-endpoint rate limits apply on the Linnworks API.

How the Channelengine and Linnworks connectors work
Channelengine
- Integration surface
- REST API (Merchant API v2); per-tenant base URL https://{tenant}.channelengine.net/api
- Authentication
- API key passed as the 'apikey' parameter; ChannelEngine recommends sending it in a request header rather than the URL because some webservers log full URLs
- Change detection
- Webhooks fire on order creation and on return and shipment/cancellation changes; product content and offers use change-tracking endpoints (GET /v2/products/data and /v2/products/offers) with an acknowledge pattern that returns only changed records, plus polling GET /v2/orders/new
