Why teams connect Klaviyo and Ukg Pro

Keep the people, teams, and status that Klaviyo and Ukg Pro share aligned in real time, so a hire, role change, or departure recorded in one reaches the other within seconds.

Each tool in Klaviyo keeps its own list of who can use it: users, members, or agents, along with the team they sit on and whether they are still active. Ukg Pro is the authoritative record of the same people as employees, with their department, manager, and employment status. When those two are connected only by manual account admin or a periodic export, the work tools drift: new hires wait days for access, team and manager changes never catch up, and people who have left keep standing accounts.

Stacksync syncs Catalog Items, Tags, Profiles, Lists in Klaviyo with Job / Position History, Compensation Details, Payroll (Pay Statements, Direct Deposit, Earnings), Terminations in Ukg Pro bi-directionally and in real time. A person added, moved, or offboarded in Ukg Pro creates or updates the matching user in Klaviyo within seconds, with field-level mapping and conflict resolution in place of spreadsheets and one-off account changes. Where Klaviyo captures details of its own, such as a corrected contact or a login identity, those can flow back to Ukg Pro in whichever direction you configure.

Because the sync is field-level, each system keeps its own extras; only the shared facts, who a person is, which team they belong to, and whether their access should be on, are held in agreement.

Common use cases

  • 01 Sync catalog items from an ERP or PIM so product recommendations and back-in-stock flows use current data
  • 02 Sync customer profiles between Klaviyo and the CRM or warehouse so segments can use fields beyond storefront data
  • 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

One employee directory

A person's name, title, contact details, or status corrected in either system updates the other, so both sides stop maintaining separate copies of the same person.

Org and team structure kept current

Department, team, and reporting-line changes from Ukg Pro keep the groups, queues, or projects in Klaviyo assigned to the right people.

Where Klaviyo routes or assigns work by person: assignments follow the org

When someone changes teams or managers in Ukg Pro, the queues, ownership, or approvals in Klaviyo update to match, so work reaches whoever holds the role now.

What you can sync between Klaviyo 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.

Klaviyo objects Ukg Pro objects How this pairing syncs
Catalog Items Product catalog records synced from an ERP or PIM power product blocks and back-in-stock triggers. 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. Catalog Items is specific to Klaviyo and Employee (Person Details) to Ukg Pro — each maps to any object or custom field on the other side.
Tags Organizational labels on campaigns, flows, and lists support reporting rollups. Employment Details Employment status, hire and service dates, and company assignment; the record that drives active/terminated state for provisioning downstream. Tags is specific to Klaviyo and Employment Details to Ukg Pro — each maps to any object or custom field on the other side.
Profiles Person records with arbitrary custom properties are the target for CRM and warehouse-sourced attributes. Job / Position History Effective-dated job, position, department, supervisor, location, and cost center; the most-synced record for org charts, provisioning, and analytics. Profiles is specific to Klaviyo and Job / Position History to Ukg Pro — each maps to any object or custom field on the other side.
Lists Static audience memberships sync in from CRMs and forms for targeting. 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. Lists is specific to Klaviyo and Compensation Details to Ukg Pro — each maps to any object or custom field on the other side.
Segments Dynamic audiences are readable so other tools can mirror who qualifies. 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. Segments is specific to Klaviyo and Payroll (Pay Statements, Direct Deposit, Earnings) to Ukg Pro — each maps to any object or custom field on the other side.
Events Timestamped behavioral records tied to metrics; external order and product events are pushed in to trigger flows. Terminations Termination transactions posted with a terminationDate and a reason code that must match the tenant's configured reason table; drives account deprovisioning. Events is specific to Klaviyo and Terminations to Ukg Pro — each maps to any object or custom field on the other side.

How changes propagate between Klaviyo 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.

Klaviyo Ukg Pro Sub-second propagation

DetectionKlaviyo notifies Stacksync of record changes through webhook events. Polling on updated timestamps.

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

Rate-limit considerations

  • Klaviyo: Per-endpoint burst and steady rate limits apply.
  • 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 Klaviyo and Ukg Pro connectors work

Klaviyo

Integration surface
REST API compliant with the JSON:API specification
Authentication
OAuth 2.0 for apps or private API keys
Change detection
Polling on updated timestamps; outbound webhooks exist for event topics (availability depends on plan or app-partner status) and as flow webhook actions
Capabilities

Rate limits
Per-endpoint burst and steady rate limits apply

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.
