Why teams connect Apollo.io and Oracle Fusion Cloud HCM

Keep the people who own accounts in Apollo.io in step with the workforce records in Oracle Fusion Cloud HCM, so ownership, roles, and org structure stay current in both systems, in real time and in both directions.

Apollo.io runs on people as much as on accounts: every contact, deal, and account has an owner, and those owners are employees whose roles, teams, and status are held in Oracle Fusion Cloud HCM. Oracle Fusion Cloud HCM is the system of record for the workforce, from new hires to promotions to departures, and often for the candidates the business is still deciding on. When the two systems are connected only by re-keying or an overnight export, they drift apart, and the CRM ends up assigning accounts to people who have left, holding territories that no longer match the org chart, and waiting days to give a new rep access.

Stacksync syncs Contacts, Accounts, People (database records), Sequences in Apollo.io with Positions, Departments (Organizations), Locations, Grades and Salaries in Oracle Fusion Cloud HCM field by field, in real time, and in both directions. You decide which system owns which fields, so Oracle Fusion Cloud HCM stays authoritative on roles and org structure while Apollo.io keeps ownership and territory current, and Stacksync resolves conflicts by the rules you set.

Common use cases

  • 01 Land sequence enrollment status and outcomes in a warehouse for outbound performance reporting.
  • 02 Deduplicate contacts across Apollo and the CRM by syncing on email as the match key.
  • 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

Where Oracle Fusion Cloud HCM tracks people the business also engages: contacts stay in sync

A person recorded in Oracle Fusion Cloud HCM, such as a candidate or applicant, can create or update the matching contact in Apollo.io, so relationship history and outreach are not rebuilt from scratch when the same individual appears in both.

New team members provisioned when they are hired

When Oracle Fusion Cloud HCM records a new hire, a matching user or owner is created in Apollo.io, so a new rep can start working accounts without waiting on a manual setup ticket.

Ownership and territory follow the org chart

When a person changes team, manager, or region in Oracle Fusion Cloud HCM, their accounts and territory assignments in Apollo.io update to match, so pipeline stays with the right owner.

What you can sync between Apollo.io 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.

Apollo.io objects Oracle Fusion Cloud HCM objects How this pairing syncs
Sequences Outreach cadences (emailer campaigns in the API); enrollment status is read to track which contacts are being worked. 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. Sequences is specific to Apollo.io and Workers (publicWorkers) to Oracle Fusion Cloud HCM — each maps to any object or custom field on the other side.
Deals (Opportunities) Pipeline records that can be read and written to keep Apollo aligned with the CRM of record. Assignments Child of a worker's work relationship carrying job, position, department, location, grade, and manager; effective-dated, so writes go through PATCH with an effective date. Deals (Opportunities) is specific to Apollo.io and Assignments to Oracle Fusion Cloud HCM — each maps to any object or custom field on the other side.
Tasks and calls Rep activity records synced for activity reporting and coaching workflows. Jobs Job catalog reference data; commonly read out to align titles and job codes in a warehouse or written to keep downstream systems consistent. Tasks and calls is specific to Apollo.io and Jobs to Oracle Fusion Cloud HCM — each maps to any object or custom field on the other side.
Custom fields Account- and contact-level custom attributes mapped field-by-field in a sync. Positions Position-management records used where positions control headcount; synced to keep vacancy and reporting structures aligned with finance/ERP. Custom fields is specific to Apollo.io and Positions to Oracle Fusion Cloud HCM — each maps to any object or custom field on the other side.
Contacts People saved to your Apollo account, synced with emails, phone numbers, and enrichment fields. Departments (Organizations) Org-structure records that define cost centers and reporting lines; typically mastered in HCM and read into other systems. Contacts is specific to Apollo.io and Departments (Organizations) to Oracle Fusion Cloud HCM — each maps to any object or custom field on the other side.
Accounts Company records with firmographic attributes, matched to CRM accounts during sync. Locations Physical work locations referenced by assignments; synced so downstream provisioning and directory tools resolve the same location codes. Accounts is specific to Apollo.io and Locations to Oracle Fusion Cloud HCM — each maps to any object or custom field on the other side.

How changes propagate between Apollo.io 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.

Apollo.io Oracle Fusion Cloud HCM Interval-based propagation

DetectionStacksync polls Apollo.io for changes on an incremental schedule, reading only records changed since the previous pass. Polling on updated-at 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 Apollo.io 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 Apollo.io through its API, with automatic retries and rate-limit backoff.

Rate-limit considerations

  • Apollo.io: Rate limits and enrichment credits vary by plan; bulk endpoints are throttled separately from single-record calls.
  • 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.
