Why teams connect Linnworks and Zoho CRM
Close the gap between front office and back office: Zoho CRM and Linnworks share customers and status in real time, in both directions.
Zoho CRM holds the customer relationship; Linnworks runs the operations and records behind the business. The two overlap wherever the same organizations and transactions matter to both, and when that overlap is bridged by re-keying or overnight batch, each side spends the day working from stale data.
Stacksync syncs Task, Meeting, Call, Product in Zoho CRM with Purchase Orders, Suppliers, Channel Listings, Returns & Refunds in Linnworks field by field, in real time, and in both directions. You decide which system owns which fields; Stacksync keeps every copy consistent and resolves conflicts by rules you set.
Common use cases
- 01 Push warehouse-computed lead scores and product signals into Zoho CRM fields for rep prioritization.
- 02 Keep Zoho CRM accounts aligned with an ERP or accounting system on customers and invoices.
- 03 Sync orders from Linnworks into an ERP or accounting system as they are processed, without CSV exports
- 04 Keep stock levels consistent between Linnworks and external systems so multichannel listings stay aligned with sellable stock
Common sync patterns
One customer master
Where both systems keep customer or organization records, corrections in either propagate to the other, ending dual maintenance.
Where Linnworks manages people and org data: keep Zoho CRM aligned
Owners, territories, and org structure informed by Linnworks stay current in Zoho CRM.
Where Linnworks handles order-to-cash: closed-won flows through
A deal won in Zoho CRM creates or updates the customer in Linnworks with clean data, so fulfillment and invoicing start without re-entry.
What you can sync between Linnworks and Zoho CRM
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.

How changes propagate between Linnworks and Zoho CRM
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.
Linnworks Zoho CRM 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 Zoho CRM through its API, with automatic retries and rate-limit backoff.
Zoho CRM Linnworks Sub-second propagation
DetectionZoho CRM notifies Stacksync of record changes through webhook events. Notification API (webhooks) on watched modules, with polling on Modified_Time.
DeliveryEach detected change is written to Linnworks through its API, with automatic retries and rate-limit backoff.
Rate-limit considerations
- Linnworks: Per-endpoint rate limits apply on the Linnworks API.
- Zoho CRM: API credits are allocated per day and vary by edition.

Authentication: OAuth-style in-app authorization: from "Create new sync" select Zoho CRM, a new tab opens where you log in to Zoho and authorize Stacksync (no coding required). Stacksync manages authentication, retries, and rate limits on both sides.
-
Zoho CRM: Data is organized into modules, standard and custom alike, and all modules are served through the same versioned REST endpoints. 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. Stacksync's field mapping accounts for these differences between Linnworks and Zoho CRM without custom code.
