Why teams connect Klaviyo and Success Factors

Keep the people, teams, and status that Klaviyo and Success Factors 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. Success Factors 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 Tags, Profiles, Lists, Segments in Klaviyo with PerPerson, EmpEmployment, EmpJob, EmpCompensation in Success Factors bi-directionally and in real time. A person added, moved, or offboarded in Success Factors 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 Success Factors 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 Replicate EmpCompensation and EmpJob effective-dated history into a warehouse for headcount, attrition, and compensation reporting without CSV pulls.
  • 04 Keep Foundation Objects (department, location, cost center) aligned between SuccessFactors and an ERP so cost-center and org hierarchies match.

Common sync patterns

Onboarding: access ready on day one

A new hire recorded in Success Factors 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.

Offboarding: no standing access after a departure

When someone is marked as leaving in Success Factors, the matching account in Klaviyo is deactivated or flagged, so departures do not leave open access behind.

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.

What you can sync between Klaviyo and Success Factors

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 Success Factors objects How this pairing syncs
Profiles Person records with arbitrary custom properties are the target for CRM and warehouse-sourced attributes. Foundation Objects (FODepartment, FOLocation, FOCostCenter) Org-structure master data (department, location, cost center, division); mastered elsewhere and written in, or read out to build org charts. Profiles is specific to Klaviyo and Foundation Objects (FODepartment, FOLocation, FOCostCenter) to Success Factors — each maps to any object or custom field on the other side.
Lists Static audience memberships sync in from CRMs and forms for targeting. Position Position Management records for headcount and requisition planning; synced with an ATS or ERP to keep positions and reqs aligned. Lists is specific to Klaviyo and Position to Success Factors — each maps to any object or custom field on the other side.
Segments Dynamic audiences are readable so other tools can mirror who qualifies. PerEmail and PerPhone Contact sub-entities under PerPerson; synced two-way with a directory or comms system to keep worker contact data current. Segments is specific to Klaviyo and PerEmail and PerPhone to Success Factors — 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. User Core identity/User entity behind role-based permissions; a model distinct from Employee Central, synced two-way with a directory or IdP and downstream apps. Events is specific to Klaviyo and User to Success Factors — 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. PerPerson Person-level container in Employee Central holding biographical data; effective-dated child entities (PerPersonal, PerEmail, PerPhone) hang off it. Metrics is specific to Klaviyo and PerPerson to Success Factors — each maps to any object or custom field on the other side.
Campaigns Email and SMS sends expose performance data for warehouse-based reporting. EmpEmployment Employment record tying a person to an employment period (hire, service dates); carries lastModifiedDateTime used for incremental polling. Campaigns is specific to Klaviyo and EmpEmployment to Success Factors — each maps to any object or custom field on the other side.

How changes propagate between Klaviyo and Success Factors

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 Success Factors Sub-second propagation

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

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

Success Factors Klaviyo Sub-second propagation

DetectionSuccess Factors notifies Stacksync of record changes through webhook events. Polling on each entity's lastModifiedDateTime / lastModifiedOn (effective-dated entities require date-range handling).

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.
  • Success Factors: OData calls are throttled at the tenant level (Access Limits for OData V2); large reads must be paginated (default page size 1000) via $top/$skip or paging cursors.
