Why teams connect Klaviyo and Ukg Ready

Keep the people, teams, and status that Klaviyo and Ukg Ready 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 Ready 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 Compensation, Timesheet Entries, Accruals / Time Off, Payroll (Earnings / Deductions / Employee Payroll Runs) in Ukg Ready bi-directionally and in real time. A person added, moved, or offboarded in Ukg Ready 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 Ready 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 Mirror Cost Centers/Groups and Compensation into finance and planning systems for headcount and budget reconciliation.
  • 04 Two-way sync Employees and Employment/Position records with an operational Postgres database so internal apps and IT provisioning read job title, department, and status in SQL while HR edits in UKG Ready.

Common sync patterns

Org and team structure kept current

Department, team, and reporting-line changes from Ukg Ready 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 Ready, the queues, ownership, or approvals in Klaviyo update to match, so work reaches whoever holds the role now.

Onboarding: access ready on day one

A new hire recorded in Ukg Ready creates the matching user in Klaviyo with the right team and manager already set, so people can start working without waiting on a provisioning ticket.

What you can sync between Klaviyo and Ukg Ready

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 Ready objects How this pairing syncs
Lists Static audience memberships sync in from CRMs and forms for targeting. Payroll (Earnings / Deductions / Employee Payroll Runs) Earnings and deductions can be imported into pay runs; Employee Payroll Runs (gross, net, taxes) read back for GL posting and analytics. Lists is specific to Klaviyo and Payroll (Earnings / Deductions / Employee Payroll Runs) to Ukg Ready — each maps to any object or custom field on the other side.
Segments Dynamic audiences are readable so other tools can mirror who qualifies. Benefits Plan enrollments, coverage tiers, contributions, and effective dates; typically read into benefits or finance systems. Segments is specific to Klaviyo and Benefits to Ukg Ready — 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. Cost Centers / Groups Departments, locations, and hierarchy used as org structure; read to align headcount and budget models across systems. Events is specific to Klaviyo and Cost Centers / Groups to Ukg Ready — each maps to any object or custom field on the other side.
Metrics Event type definitions organize the activity stream used in segmentation and attribution. Reports (Report-as-a-Service) Scheduled IBM Cognos extracts used for bulk historical pulls that the per-employee REST endpoints are not built for. Metrics is specific to Klaviyo and Reports (Report-as-a-Service) to Ukg Ready — each maps to any object or custom field on the other side.
Campaigns Email and SMS sends expose performance data for warehouse-based reporting. Employees Core person records (demographics, contact info, status, work location); synced two-way and mapped to HRIS or person tables in a database. Campaigns is specific to Klaviyo and Employees to Ukg Ready — each maps to any object or custom field on the other side.
Flows Automation definitions and their engagement data sync outward for attribution. Employment / Positions Job title, department, employment type, hire and termination dates; read for org modeling and written when roles change. Flows is specific to Klaviyo and Employment / Positions to Ukg Ready — each maps to any object or custom field on the other side.

How changes propagate between Klaviyo and Ukg Ready

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 Ready Sub-second propagation

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

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

Ukg Ready Klaviyo Sub-second propagation

DetectionUkg Ready notifies Stacksync of record changes through webhook events. UKG Webhooks for select events (employee.created, employee.updated, account/org changes) with HMAC signing.

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

Rate-limit considerations

  • Klaviyo: Per-endpoint burst and steady rate limits apply.
  • Ukg Ready: Rate limits apply over roughly a 1-minute window and return HTTP 429 when exceeded (back off / exponential retry); UKG Webhooks run on a tiered quota with a free tier around 10,000 event notifications per month and 14-day event retention.
