Linnworks to Zoho CRM integration — real-time, two-way sync

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

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 Zoho CRM: One customer master; Where Linnworks manages people and org data: keep Zoho CRM aligned; Where Linnworks handles order-to-cash: closed-won flows through. Where both systems keep customer or organization records, corrections in either propagate to the other, ending dual maintenance.

Linnworks: REST API. Authentication: Application credentials and an install token exchanged for a session token. Zoho CRM: REST API. 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.

Stacksync is SOC 2 Type II and ISO 27001 certified with HIPAA BAA support. Data is encrypted in transit, and a zero-persistent-storage architecture means Linnworks and Zoho CRM records are not retained after a sync operation.
