Why teams connect Lemlist and Ukg Pro

Keep the people, teams, and status that Lemlist 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 Lemlist 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 Unsubscribes, Webhooks, Team Members, Campaigns in Lemlist with Configuration Setup (Code Tables), Time & Attendance (UTA), Employee (Person Details), Employment Details 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 Lemlist within seconds, with field-level mapping and conflict resolution in place of spreadsheets and one-off account changes. Where Lemlist 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 Push enriched leads from a warehouse or list-building workflow into Lemlist campaigns automatically
  • 02 Propagate unsubscribes and bounces back to the CRM and other outreach tools for suppression compliance
  • 03 Deprovision accounts by subscribing to UKG Pro termination and job-change webhook events to disable IdP and app access as changes become effective.
  • 04 Keep Configuration code tables (jobs, locations, departments, cost centers) aligned between UKG Pro and an ERP so org and cost-center hierarchies match.

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 Lemlist assigned to the right people.

Where Lemlist 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 Lemlist update to match, so work reaches whoever holds the role now.

What you can sync between Lemlist 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.

Lemlist objects Ukg Pro objects How this pairing syncs
Team Members Sender and seat records map outreach activity to reps in other systems. Employment Details Employment status, hire and service dates, and company assignment; the record that drives active/terminated state for provisioning downstream. Team Members is specific to Lemlist and Employment Details to Ukg Pro — each maps to any object or custom field on the other side.
Campaigns Outreach campaigns are the container leads are pushed into from CRMs and list-building workflows. Job / Position History Effective-dated job, position, department, supervisor, location, and cost center; the most-synced record for org charts, provisioning, and analytics. Campaigns is specific to Lemlist and Job / Position History to Ukg Pro — each maps to any object or custom field on the other side.
Leads Per-campaign prospect records sync in from enrichment sources and back out with status. 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. Leads is specific to Lemlist and Compensation Details to Ukg Pro — each maps to any object or custom field on the other side.
Activities Engagement records such as opens, clicks, replies, and bounces sync to CRM timelines. 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. Activities is specific to Lemlist and Payroll (Pay Statements, Direct Deposit, Earnings) to Ukg Pro — each maps to any object or custom field on the other side.
Unsubscribes Opt-out records propagate to other outreach tools and the CRM for compliance. Terminations Termination transactions posted with a terminationDate and a reason code that must match the tenant's configured reason table; drives account deprovisioning. Unsubscribes is specific to Lemlist and Terminations to Ukg Pro — each maps to any object or custom field on the other side.
Webhooks Hook subscriptions define which activity events are pushed to external endpoints. 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. Webhooks is specific to Lemlist and Configuration Setup (Code Tables) to Ukg Pro — each maps to any object or custom field on the other side.

How changes propagate between Lemlist 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.

Lemlist Ukg Pro Sub-second propagation

DetectionLemlist notifies Stacksync of record changes through webhook events. Webhooks on outreach activity events, plus polling.

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

Rate-limit considerations

  • Lemlist: 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.

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.
