Why teams connect Klaviyo and Oracle Fusion Cloud HCM

Keep the people, teams, and status that Klaviyo and Oracle Fusion Cloud HCM 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. Oracle Fusion Cloud HCM 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 Grades and Salaries, Absences (workerAbsenceEntries), Workers (publicWorkers), Assignments in Oracle Fusion Cloud HCM bi-directionally and in real time. A person added, moved, or offboarded in Oracle Fusion Cloud HCM 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 Oracle Fusion Cloud HCM 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 Grades and Salaries into a warehouse for compensation and headcount analytics without exporting HDL files.
  • 04 Keep Positions and Departments aligned between Oracle HCM and a finance/ERP system so cost centers and reporting structures match.

Common sync patterns

Org and team structure kept current

Department, team, and reporting-line changes from Oracle Fusion Cloud HCM 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 Oracle Fusion Cloud HCM, 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 Oracle Fusion Cloud HCM 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 Oracle Fusion Cloud HCM

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 Oracle Fusion Cloud HCM objects How this pairing syncs
Lists Static audience memberships sync in from CRMs and forms for targeting. Positions Position-management records used where positions control headcount; synced to keep vacancy and reporting structures aligned with finance/ERP. Lists is specific to Klaviyo and Positions to Oracle Fusion Cloud HCM — each maps to any object or custom field on the other side.
Segments Dynamic audiences are readable so other tools can mirror who qualifies. Departments (Organizations) Org-structure records that define cost centers and reporting lines; typically mastered in HCM and read into other systems. Segments is specific to Klaviyo and Departments (Organizations) to Oracle Fusion Cloud HCM — 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. Locations Physical work locations referenced by assignments; synced so downstream provisioning and directory tools resolve the same location codes. Events is specific to Klaviyo and Locations to Oracle Fusion Cloud HCM — 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. Grades and Salaries Grade, grade-rate, and worker compensation records; usually read out for compensation and headcount analytics, and written back for corrections. Metrics is specific to Klaviyo and Grades and Salaries to Oracle Fusion Cloud HCM — each maps to any object or custom field on the other side.
Campaigns Email and SMS sends expose performance data for warehouse-based reporting. Absences (workerAbsenceEntries) Time-off and leave entries; synced into scheduling or workforce-management databases for coverage planning. Campaigns is specific to Klaviyo and Absences (workerAbsenceEntries) to Oracle Fusion Cloud HCM — each maps to any object or custom field on the other side.
Flows Automation definitions and their engagement data sync outward for attribution. Workers (publicWorkers) Person master with personNumber, names, national IDs, and work relationships; synced two-way via the /workers resource, which replaced the desupported /emps resource. Flows is specific to Klaviyo and Workers (publicWorkers) to Oracle Fusion Cloud HCM — each maps to any object or custom field on the other side.

How changes propagate between Klaviyo and Oracle Fusion Cloud HCM

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 Oracle Fusion Cloud HCM Sub-second propagation

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

DeliveryEach detected change is written to Oracle Fusion Cloud HCM through its API, with automatic retries and rate-limit backoff.

Oracle Fusion Cloud HCM Klaviyo Sub-second propagation

DetectionChanges in Oracle Fusion Cloud HCM are captured at the source via change data capture — no polling loop against its API. Atom feeds expose changes-only feeds for key events (new hire, termination, assignment change).

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.
  • Oracle Fusion Cloud HCM: Oracle publishes no fixed per-tenant REST rate limit; pages are capped via limit/offset and Oracle recommends client-side throttling, backoff, and using HDL for mass loads rather than transactional REST.
