Why teams connect InterSystems IRIS and Ukg Pro

Put your workforce data where your apps can reach it: InterSystems IRIS and Ukg Pro share the same people, positions, and org structure in real time.

Ukg Pro is the system of record for the people side of the business — employees, candidates, roles, and the org structure around them. InterSystems IRIS is where internal tools, dashboards, provisioning jobs, and analytics actually read and store records. The overlap is the workforce itself: Configuration Setup (Code Tables), Time & Attendance (UTA), Employee (Person Details), Employment Details in Ukg Pro need to exist as queryable Persistent Classes, Globals, Namespaces, Stored Procedures in InterSystems IRIS before an app can act on them. When that bridge is a nightly export or a hand-run CSV, every downstream system spends the day working from a roster that has already moved on.

Stacksync syncs Persistent Classes, Globals, Namespaces, Stored Procedures in InterSystems IRIS with Configuration Setup (Code Tables), Time & Attendance (UTA), Employee (Person Details), Employment Details in Ukg Pro field by field, in real time. You decide which system owns which fields — Ukg Pro typically owns identity and org attributes, while operational or computed values can flow back the other way — and Stacksync keeps every copy consistent, matching records on a stable key and resolving conflicts by rules you set.

The result is one live picture of the workforce on both sides: HR keeps its source of truth, and the database keeps a current mirror that internal apps, reports, and access controls can trust without a batch window in between.

Common use cases

  • 01 Write enriched or corrected records from SaaS apps back into IRIS tables for on-platform processing
  • 02 Replicate IRIS tables to Postgres so application teams can build against a familiar database
  • 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

Reporting and analytics on current data

Configuration Setup (Code Tables), Time & Attendance (UTA), Employee (Person Details), Employment Details replicate into InterSystems IRIS where they join operational tables, so headcount, roles, and status reports run on the live state without manual pulls.

Org and structure stay aligned

Groups, departments, managers, and reporting lines from Ukg Pro stay consistent in InterSystems IRIS, so hierarchy-driven logic and permissions don't drift.

Computed and operational fields flow back

Values assembled or corrected in InterSystems IRIS write onto the matching record in Ukg Pro where those fields are writable, keeping the people system enriched.

What you can sync between InterSystems IRIS 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.

InterSystems IRIS objects Ukg Pro objects How this pairing syncs
Stored Procedures Server-side logic callable over SQL supports controlled writes and transformations. 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. Stored Procedures is specific to InterSystems IRIS and Configuration Setup (Code Tables) to Ukg Pro — each maps to any object or custom field on the other side.
Tables Relational projections of stored data are the primary read/write surface for SQL-based syncs. Time & Attendance (UTA) Timekeeping and worked-hours data exposed by the UTA services; synced into scheduling, payroll, or workforce-analytics databases. Tables is specific to InterSystems IRIS and Time & Attendance (UTA) to Ukg Pro — each maps to any object or custom field on the other side.
Views SQL views expose curated slices of data for outbound replication. 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. Views is specific to InterSystems IRIS and Employee (Person Details) to Ukg Pro — each maps to any object or custom field on the other side.
Schemas Schema organization scopes which tables a sync connection can see. Employment Details Employment status, hire and service dates, and company assignment; the record that drives active/terminated state for provisioning downstream. Schemas is specific to InterSystems IRIS and Employment Details to Ukg Pro — each maps to any object or custom field on the other side.
Persistent Classes Object-model classes project to tables, so class data is reachable through SQL. Job / Position History Effective-dated job, position, department, supervisor, location, and cost center; the most-synced record for org charts, provisioning, and analytics. Persistent Classes is specific to InterSystems IRIS and Job / Position History to Ukg Pro — each maps to any object or custom field on the other side.
Globals The underlying multidimensional storage; typically accessed indirectly via SQL or objects in syncs. 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. Globals is specific to InterSystems IRIS and Compensation Details to Ukg Pro — each maps to any object or custom field on the other side.

How changes propagate between InterSystems IRIS 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.

InterSystems IRIS Ukg Pro Interval-based propagation

DetectionStacksync polls InterSystems IRIS for changes on an incremental schedule, reading only records changed since the previous pass. Polling (timestamp or query-based).

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

Ukg Pro InterSystems IRIS Sub-second propagation

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

DeliveryEach detected change is applied to InterSystems IRIS as a row-level write, with types converted between the two schemas.

Rate-limit considerations

  • InterSystems IRIS: Constrained by database resources rather than published API rate limits.
  • 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.

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.
