Why teams connect Infor LN and Ukg Pro

Sync the workers, org structure, and cost centers that Infor LN 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. Infor LN 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 Purchase orders, Production orders, Warehouse / inventory, Projects in Infor LN with Compensation Details, Payroll (Pay Statements, Direct Deposit, Earnings), Terminations, Configuration Setup (Code Tables) 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 Infor LN 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 Keep inventory positions aligned between LN and distribution or aftermarket service systems.
  • 02 Sync item masters, BOMs, and production orders between LN and MES or PLM systems on the shop floor.
  • 03 Replicate Compensation and pay-statement / earnings history into a warehouse for headcount, labor-cost, and payroll reporting without manual BI exports.
  • 04 Deprovision accounts by subscribing to UKG Pro termination and job-change webhook events to disable IdP and app access as changes become effective.

Common sync patterns

New hires ready to transact in Infor LN

A new person set up in Ukg Pro becomes an employee record in Infor LN in time to submit expenses, enter time, or approve a purchase, without waiting on manual setup.

One org structure

Departments, cost centers, and locations that both systems reference stay in agreement, so labor cost, approvals, and reporting in Infor LN roll up to the same structure Ukg Pro maintains.

Reporting lines drive approvals

Manager and reporting-hierarchy changes in Ukg Pro keep expense and purchase approval chains in Infor LN pointed at the right people.

What you can sync between Infor LN 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.

Infor LN objects Ukg Pro objects How this pairing syncs
Warehouse / inventory Stock positions exposed so external channels reflect real availability. 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. Warehouse / inventory is specific to Infor LN and Payroll (Pay Statements, Direct Deposit, Earnings) to Ukg Pro — each maps to any object or custom field on the other side.
Projects Project structures used in engineer-to-order manufacturing scenarios. Terminations Termination transactions posted with a terminationDate and a reason code that must match the tenant's configured reason table; drives account deprovisioning. Projects is specific to Infor LN and Terminations to Ukg Pro — each maps to any object or custom field on the other side.
Service orders Aftermarket service documents synced with field service tools. 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. Service orders is specific to Infor LN and Configuration Setup (Code Tables) to Ukg Pro — each maps to any object or custom field on the other side.
Items Manufacturing item masters synced to PLM, MES, and commerce systems. Time & Attendance (UTA) Timekeeping and worked-hours data exposed by the UTA services; synced into scheduling, payroll, or workforce-analytics databases. Items is specific to Infor LN and Time & Attendance (UTA) to Ukg Pro — each maps to any object or custom field on the other side.
Bills of material Product structures shared with engineering and planning tools. Employee (Person Details) Core worker record with demographics and identifiers; read by listing employee IDs then fetching each profile, and created on hire via the personnel/onboarding endpoints. Bills of material is specific to Infor LN and Employee (Person Details) to Ukg Pro — each maps to any object or custom field on the other side.
Business partners LN's unified customer/supplier records matched against CRM accounts. Employment Details Employment status, hire and service dates, and company assignment; the record that drives active/terminated state for provisioning downstream. Business partners is specific to Infor LN and Employment Details to Ukg Pro — each maps to any object or custom field on the other side.

How changes propagate between Infor LN 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.

Infor LN Ukg Pro Interval-based propagation

DetectionStacksync polls Infor LN for changes on an incremental schedule, reading only records changed since the previous pass. Event-style BOD publications through Infor ION where configured.

DeliveryEach detected change is written to Ukg Pro through its API, with automatic retries and rate-limit backoff.

Ukg Pro Infor LN Sub-second propagation

DetectionUkg Pro notifies Stacksync of record changes through webhook events. No CDC stream.

DeliveryEach detected change is written to Infor LN through its API, with automatic retries and rate-limit backoff.

Rate-limit considerations

  • Infor LN: Subject to the ION API gateway's tenant rate limits in cloud deployments.
  • 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.

How the Infor LN and Ukg Pro connectors work

Infor LN

Integration surface
SOAP and REST web services, with standardized BOD exchange through Infor ION in Infor OS deployments
Authentication
OAuth 2.0 via the ION API gateway in cloud deployments; application credentials on premises
Change detection
Event-style BOD publications through Infor ION where configured; otherwise polling

Rate limits

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.
