Why teams connect Linnworks and Salesforce Marketing Cloud

Feed the real customer, order, and revenue records from Linnworks into Salesforce Marketing Cloud so campaigns run on who actually bought what, and let contact and consent changes flow back in real time.

Marketing runs on lists of people, but the list rarely knows which of those people are paying customers, what they ordered, or what they are worth. Linnworks holds exactly that: Channel Listings, Returns & Refunds, Shipping Services, Open Orders that record who the customer is, what they bought, and what they owe. When the two are joined only by a periodic export, campaigns go out against stale audiences, existing customers get prospecting emails, high-value accounts look the same as cold leads, and a canceled order still counts toward a segment.

Stacksync syncs Channel Listings, Returns & Refunds, Shipping Services, Open Orders in Linnworks with Content Assets (Content Builder), Automations (Automation Studio), Tracking Events, Transactional Sends in Salesforce Marketing Cloud in real time, and where both sides accept writes, in both directions. Customer, order, and invoice data maps field by field onto the contacts, audiences, or accounts Salesforce Marketing Cloud works with, so segmentation and personalization run on current purchase history instead of a month-old snapshot. Contact details and consent changes that originate in Salesforce Marketing Cloud flow back onto the record in Linnworks.

The strongest bridge between the two is identity and purchase history, who the customer is and what they have bought, so that is where most of the value sits. Because the sync is field-level, each system keeps the attributes the other has no use for; only the shared records are held in agreement.

Common use cases

  • 01 Sync product and listing data with a PIM so channel listings stay aligned with the catalog
  • 02 Push customer and order data to a CRM or marketing platform for post-purchase campaigns
  • 03 Fire Journey Builder entry events (/interaction/v1/events) from an app or database when a contact acts, so behavioral journeys trigger on live events instead of scheduled batch loads.
  • 04 Land tracking events - Sent, Open, Click, Bounce, Unsubscribe - from the SOAP tracking objects or Automation Studio Data Views into a warehouse table for per-send deliverability reporting.

Common sync patterns

Consent and contact changes travel

Email, address, or subscription-status changes stay aligned across both systems, so a customer who updates their details or opts out is respected everywhere.

Purchase history drives segmentation

Orders, invoices, and revenue totals from Linnworks land on the matching contact or account in Salesforce Marketing Cloud, so audiences are built from what customers actually bought and spent rather than from guesses.

Suppress or target existing customers

Because Linnworks knows who is already a paying customer, Salesforce Marketing Cloud can exclude them from acquisition campaigns or single them out for renewal and cross-sell.

What you can sync between Linnworks and Salesforce Marketing Cloud

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.

Linnworks objects Salesforce Marketing Cloud objects How this pairing syncs
Locations Warehouse and fulfillment location records scope stock data during mapping. Contacts / Subscribers The contact model keyed by Subscriber Key, holding channel addresses and subscription status; managed through the Contacts API (/contacts/v1/contacts) and the SOAP Subscriber object, and referenced by every send and journey. Locations is specific to Linnworks and Contacts / Subscribers to Salesforce Marketing Cloud — each maps to any object or custom field on the other side.
Purchase Orders Replenishment POs sync with suppliers and accounting systems. Journeys (Journey Builder) Multi-step automated flows read and managed via /interaction/v1/interactions; contacts are injected by firing an entry event to /interaction/v1/events with an EventDefinitionKey and contact data. Purchase Orders is specific to Linnworks and Journeys (Journey Builder) to Salesforce Marketing Cloud — each maps to any object or custom field on the other side.
Suppliers Vendor records keep procurement data consistent across tools. Content Assets (Content Builder) Emails, templates, images, and reusable content blocks stored in Content Builder and read or written via /asset/v1/content/assets, used to compose the messages a journey or send delivers. Suppliers is specific to Linnworks and Content Assets (Content Builder) to Salesforce Marketing Cloud — each maps to any object or custom field on the other side.
Channel Listings Marketplace and webstore listing mappings tie channel products to internal SKUs. Automations (Automation Studio) Scheduled or triggered workflows of import, query, extract, and send activities managed via /automation/v1/automations; SQL Query Activities read Data Views and write results into Data Extensions. Channel Listings is specific to Linnworks and Automations (Automation Studio) to Salesforce Marketing Cloud — each maps to any object or custom field on the other side.
Returns & Refunds Post-sale records flow to finance and support systems. Tracking Events Sent, Open, Click, Bounce, Unsubscribe, and NotSent events retrieved through the SOAP tracking objects (SentEvent, OpenEvent, ClickEvent, BounceEvent) or the Automation Studio Data Views (_Sent, _Open, _Click, _Bounce) - the queryable record of engagement per send. Returns & Refunds is specific to Linnworks and Tracking Events to Salesforce Marketing Cloud — each maps to any object or custom field on the other side.
Shipping Services Carrier and service definitions support label and tracking data in order syncs. Transactional Sends Triggered and transactional Email/SMS delivered through the Messaging API (/messaging/v1/email/messages/{key}); the Event Notification Service reports each message's disposition (delivered, bounced, opened, clicked). Shipping Services is specific to Linnworks and Transactional Sends to Salesforce Marketing Cloud — each maps to any object or custom field on the other side.

How changes propagate between Linnworks and Salesforce Marketing Cloud

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 Salesforce Marketing Cloud 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 Salesforce Marketing Cloud through its API, with automatic retries and rate-limit backoff.

Salesforce Marketing Cloud Linnworks Sub-second propagation

DetectionSalesforce Marketing Cloud notifies Stacksync of record changes through webhook events. The Event Notification Service (ENS) issues HTTPS POST callbacks for transactional Email and SMS events (sent, bounce, open, click) once a callback.

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.
  • Salesforce Marketing Cloud: Salesforce does not publish fixed numeric REST rate limits; requests are throttled per account and can return HTTP 429, so backoff is advised. SOAP Retrieve returns at most 2,500 records per call and pages via ContinueRequest with the prior RequestID. Bulk Data Extension writes use the async rows API to queue inserts in the background.

Salesforce Marketing Cloud

Integration surface
Two APIs on tenant-specific endpoints: a REST API (JSON over HTTPS) for Data Extensions, Journeys, Contacts, Content Builder, and Automations, plus a legacy SOAP API (ExactTarget WSDL) for tracking events and bulk Retrieve.
Authentication
OAuth 2.0 via an Installed Package (Client ID + Client Secret). Server-to-server uses the client_credentials grant and web apps use authorization_code, both against {subdomain}.auth.marketingcloudapis.com/v2/token. The 20-minute access token response also returns the account's rest_instance_url and soap_instance_url.
Change detection
The Event Notification Service (ENS) issues HTTPS POST callbacks for transactional Email and SMS events (sent, bounce, open, click) once a callback URL and subscription are registered and verified. There is no general data-change feed, so Data Extension and Data View syncs poll by date fields.
