Why teams connect Kustomer and Ukg Pro
Keep the people who own accounts in Kustomer in step with the workforce records in Ukg Pro, so ownership, roles, and org structure stay current in both systems, in real time and in both directions.
Kustomer runs on people as much as on accounts: every contact, deal, and account has an owner, and those owners are employees whose roles, teams, and status are held in Ukg Pro. Ukg Pro is the system of record for the workforce, from new hires to promotions to departures, and often for the candidates the business is still deciding on. When the two systems are connected only by re-keying or an overnight export, they drift apart, and the CRM ends up assigning accounts to people who have left, holding territories that no longer match the org chart, and waiting days to give a new rep access.
Stacksync syncs Notes, Customers, Conversations, Messages in Kustomer with Job / Position History, Compensation Details, Payroll (Pay Statements, Direct Deposit, Earnings), Terminations in Ukg Pro field by field, in real time, and in both directions. You decide which system owns which fields, so Ukg Pro stays authoritative on roles and org structure while Kustomer keeps ownership and territory current, and Stacksync resolves conflicts by the rules you set.
Common use cases
- 01 Sync customers bi-directionally with the CRM and ERP so agents see deal, billing, and subscription context on the timeline
- 02 Push order and shipment records from commerce systems into Kustomer custom objects so agents answer order-status questions without switching tools
- 03 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.
- 04 Push new hires (Employee, Employment, Job) into an ERP, IdP, or app database when onboarding completes so account, cost-center, and payroll setup fire on hire instead of manual report exports.
Common sync patterns
One directory of people
A person's name, title, email, phone, or manager corrected in either system updates the other, so both stop maintaining separate copies of the same individual.
Where Ukg Pro tracks people the business also engages: contacts stay in sync
A person recorded in Ukg Pro, such as a candidate or applicant, can create or update the matching contact in Kustomer, so relationship history and outreach are not rebuilt from scratch when the same individual appears in both.
New team members provisioned when they are hired
When Ukg Pro records a new hire, a matching user or owner is created in Kustomer, so a new rep can start working accounts without waiting on a manual setup ticket.
What you can sync between Kustomer 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.
| Kustomer objects | Ukg Pro objects | How this pairing syncs | |
|---|---|---|---|
| Customers The central record whose timeline aggregates every interaction; external attributes sync onto it. | Job / Position History Effective-dated job, position, department, supervisor, location, and cost center; the most-synced record for org charts, provisioning, and analytics. | Customers is specific to Kustomer and Job / Position History to Ukg Pro — each maps to any object or custom field on the other side. | |
| Conversations Support threads across channels sync outward for analytics and CRM context. | 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. | Conversations is specific to Kustomer and Compensation Details to Ukg Pro — each maps to any object or custom field on the other side. | |
| Messages Individual messages within conversations support full-thread replication. | 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. | Messages is specific to Kustomer and Payroll (Pay Statements, Direct Deposit, Earnings) to Ukg Pro — each maps to any object or custom field on the other side. | |
| Companies Organization records group customers and map to CRM accounts. | Terminations Termination transactions posted with a terminationDate and a reason code that must match the tenant's configured reason table; drives account deprovisioning. | Companies is specific to Kustomer and Terminations to Ukg Pro — each maps to any object or custom field on the other side. | |
| Custom Objects (Klasses) Structured external records such as orders and subscriptions synced in to appear on the customer timeline. | 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. | Custom Objects (Klasses) is specific to Kustomer and Configuration Setup (Code Tables) to Ukg Pro — each maps to any object or custom field on the other side. | |
| Users Agent records map conversation ownership to people in other systems. | Time & Attendance (UTA) Timekeeping and worked-hours data exposed by the UTA services; synced into scheduling, payroll, or workforce-analytics databases. | Users is specific to Kustomer and Time & Attendance (UTA) to Ukg Pro — each maps to any object or custom field on the other side. |
How changes propagate between Kustomer 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.
Kustomer Ukg Pro Sub-second propagation
DetectionKustomer notifies Stacksync of record changes through webhook events. Outbound webhooks on record events, plus polling for backfill.
DeliveryEach detected change is written to Ukg Pro through its API, with automatic retries and rate-limit backoff.
Ukg Pro Kustomer Sub-second propagation
DetectionUkg Pro notifies Stacksync of record changes through webhook events. No CDC stream.
DeliveryEach detected change is written to Kustomer through its API, with automatic retries and rate-limit backoff.
Rate-limit considerations
- Kustomer: Subject to the platform's 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.

- 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
Kustomer and Ukg Pro integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Kustomer and Ukg Pro: authenticate both systems, choose the objects to sync (such as Kustomer's Customers and Conversations), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
Change detection on Kustomer: Outbound webhooks on record events, plus polling for backfill. 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.
-
On the Kustomer side: Notes, Customers, Conversations, Messages, plus custom fields where Kustomer exposes them. On the Ukg Pro side: Job / Position History, Compensation Details, Payroll (Pay Statements, Direct Deposit, Earnings), Terminations. Stacksync auto-detects both schemas and converts types between the two systems.
-
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 Kustomer and Ukg Pro: One directory of people; Where Ukg Pro tracks people the business also engages: contacts stay in sync; New team members provisioned when they are hired. A person's name, title, email, phone, or manager corrected in either system updates the other, so both stop maintaining separate copies of the same individual.
