Why teams connect Linnworks and Ukg Pro
Sync the workers, org structure, and cost centers that Linnworks and Ukg Pro share in real time, so the people Ukg Pro manages stay current in the system that runs finance and operations.
Ukg Pro is the system of record for people: who was hired, which department and location they sit in, who they report to, and how they are paid. Linnworks runs finance and operations, and much of what it does depends on that same information, from booking labor cost to approving an expense report to staffing a project. Where the two are bridged by re-keying or an overnight file, each side spends the day out of step, with new hires missing from the systems they need and leavers still active where they should not be.
Stacksync syncs Returns & Refunds, Shipping Services, Open Orders, Processed Orders in Linnworks with Time & Attendance (UTA), Employee (Person Details), Employment Details, Job / Position History in Ukg Pro field by field, in real time, and in both directions. You decide which system owns which fields, so the people side stays authoritative for worker data while Linnworks keeps its own accounting and operational detail, and every change made in one is reflected in the other within seconds instead of at the next batch run.
Common use cases
- 01 Push customer and order data to a CRM or marketing platform for post-purchase campaigns
- 02 Sync orders from Linnworks into an ERP or accounting system as they are processed, without CSV exports
- 03 Keep Configuration code tables (jobs, locations, departments, cost centers) aligned between UKG Pro and an ERP so org and cost-center hierarchies match.
- 04 Two-way sync of Employee and Job Details (position, department, supervisor, location, cost center) into Postgres so provisioning, internal apps, and analytics read current worker and org data in SQL while HR edits in UKG Pro.
Common sync patterns
Where Ukg Pro runs payroll: labor cost in the books
Pay and compensation data from Ukg Pro posts into Linnworks as labor cost, so finance sees workforce spend without re-entering it by hand.
Where Ukg Pro is the worker system of record: one employee master
When a worker is hired, moved, or offboarded in Ukg Pro, the matching employee record in Linnworks is created, updated, or deactivated, so the business system reflects the workforce as it actually is.
New hires ready to transact in Linnworks
A new person set up in Ukg Pro becomes an employee record in Linnworks in time to submit expenses, enter time, or approve a purchase, without waiting on manual setup.
What you can sync between Linnworks and Ukg Pro
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 | Ukg Pro objects | How this pairing syncs | |
|---|---|---|---|
| Shipping Services Carrier and service definitions support label and tracking data in order syncs. | Employment Details Employment status, hire and service dates, and company assignment; the record that drives active/terminated state for provisioning downstream. | Shipping Services is specific to Linnworks and Employment Details to Ukg Pro — each maps to any object or custom field on the other side. | |
| Open Orders Unshipped orders aggregated from sales channels sync into ERPs and fulfillment systems. | Job / Position History Effective-dated job, position, department, supervisor, location, and cost center; the most-synced record for org charts, provisioning, and analytics. | Open Orders is specific to Linnworks and Job / Position History to Ukg Pro — each maps to any object or custom field on the other side. | |
| Processed Orders Completed orders feed accounting and warehouse-based margin reporting. | Compensation Details Effective-dated pay rate and salary; usually read into a warehouse for comp reporting and writable as new dated changes through the compensation endpoints. | Processed Orders is specific to Linnworks and Compensation Details to Ukg Pro — each maps to any object or custom field on the other side. | |
| Stock Items SKU records keep product data aligned with ERPs and PIMs. | Payroll (Pay Statements, Direct Deposit, Earnings) Pay statements, direct-deposit accounts, and earnings history; read-only pay data replicated into finance and warehouse systems for labor-cost reporting. | Stock Items is specific to Linnworks and Payroll (Pay Statements, Direct Deposit, Earnings) to Ukg Pro — each maps to any object or custom field on the other side. | |
| Stock Levels Per-location quantities sync outward so channels and planning tools reflect current availability. | Terminations Termination transactions posted with a terminationDate and a reason code that must match the tenant's configured reason table; drives account deprovisioning. | Stock Levels is specific to Linnworks and Terminations to Ukg Pro — each maps to any object or custom field on the other side. | |
| Locations Warehouse and fulfillment location records scope stock data during mapping. | Configuration Setup (Code Tables) Reference data such as jobs, locations, positions, earnings, and deduction codes; used to resolve and validate field values when mapping records during sync. | Locations is specific to Linnworks and Configuration Setup (Code Tables) to Ukg Pro — each maps to any object or custom field on the other side. |
How changes propagate between Linnworks and Ukg Pro
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 Ukg Pro 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 Ukg Pro through its API, with automatic retries and rate-limit backoff.
Ukg Pro Linnworks Sub-second propagation
DetectionUkg Pro notifies Stacksync of record changes through webhook events. No CDC stream.
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.
- Ukg Pro: An API gateway throttles calls per client over a rolling window (typically per minute); UKG does not publish exact numeric thresholds. Exceeding the limit returns HTTP 429, and UKG recommends a roughly one-second looping backoff before resuming (a Retry-After header is not yet standard). Reads are offset-paginated.

- REST API
- Authentication
- Application credentials and an install token exchanged for a session token
- Change detection
- Polling on order and stock endpoints
- Capabilities

Ukg Pro
- Integration surface
- REST API (UKG Pro HCM REST services) with separate Onboarding and Recruiting REST APIs, plus legacy SOAP-based UKG Pro Web Services
- Authentication
- Core HCM REST APIs use HTTP Basic authentication with a dedicated web service account, plus a Customer API Key and a User API Key sent as headers (found under System Configuration > Security > Service Account Administration); the Onboarding and Recruiting REST APIs instead require a bearer Authorization Token from the token endpoint.
- Change detection
- No CDC stream. UKG Pro publishes Pro HCM Webhook Events for changes such as new hire, employee and job detail changes, termination, and PTO, which Stacksync subscribes to for near-real-time triggers; bulk and historical loads use paged reads with each service's modified-since filters.

FAQ
Linnworks and Ukg Pro integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Linnworks and Ukg Pro: authenticate both systems, choose the objects to sync (such as Linnworks's Shipping Services and Open Orders), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
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. Ukg Pro: Writes are modeled as HR events, not raw field edits: new hire (POST), termination (POST with a reason code that must match the tenant's configured reason table), and job or pay changes go through dedicated endpoints rather than a single PATCH. Stacksync's field mapping accounts for these differences between Linnworks and Ukg Pro 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 Ukg Pro records are not retained after a sync operation.
-
Stacksync pricing is usage-based and starts at $1,000/month, including the managed Linnworks and Ukg Pro connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom Linnworks–Ukg Pro integration in-house.
-
Yes — Stacksync ships production-grade connectors for both Linnworks and Ukg Pro. The connectors handle authentication, schema detection, rate limits, and retries; you configure the sync, and Stacksync operates it.
-
Change detection on Linnworks: Polling on order and stock endpoints. On Ukg Pro: No CDC stream. UKG Pro publishes Pro HCM Webhook Events for changes such as new hire, employee and job detail changes, termination, and PTO, which Stacksync subscribes to for near-real-time triggers; bulk and historical loads use paged reads with each service's modified-since filters. Each detected change propagates to the other side in milliseconds, with field-level conflict resolution and an inspectable event log.
