Why teams connect Greenhouse and Oracle Fusion ERP

Sync the workers, org structure, and cost centers that Oracle Fusion ERP and Greenhouse share in real time, so the people Greenhouse manages stay current in the system that runs finance and operations.

Greenhouse is the system of record for people: who was hired, which department and location they sit in, who they report to, and how they are paid. Oracle Fusion ERP runs finance and operations, and much of what it does depends on that same information, from booking labor cost to approving an expense report to staffing a project. Where the two are bridged by re-keying or an overnight file, each side spends the day out of step, with new hires missing from the systems they need and leavers still active where they should not be.

Stacksync syncs Receivables Invoices, Purchase Orders, Journal Entries, GL Balances in Oracle Fusion ERP with Jobs, Offers, Scorecards, Scheduled Interviews in Greenhouse field by field, in real time, and in both directions. You decide which system owns which fields, so the people side stays authoritative for worker data while Oracle Fusion ERP keeps its own accounting and operational detail, and every change made in one is reflected in the other within seconds instead of at the next batch run.

Common use cases

  • 01 Replicate GL balances and journals into a reporting database for consolidation across subsidiaries.
  • 02 Align supplier master data between Fusion Procurement and external sourcing or onboarding systems.
  • 03 Two-way sync Candidates and Applications with Postgres so recruiting-ops apps read and update stage, status, and custom fields in SQL while recruiters stay in Greenhouse.
  • 04 Write enriched or sourced Candidates from external tools into Greenhouse and keep contact fields refreshed as data changes.

Common sync patterns

One org structure

Departments, cost centers, and locations that both systems reference stay in agreement, so labor cost, approvals, and reporting in Oracle Fusion ERP roll up to the same structure Greenhouse maintains.

Reporting lines drive approvals

Manager and reporting-hierarchy changes in Greenhouse keep expense and purchase approval chains in Oracle Fusion ERP pointed at the right people.

Where Greenhouse runs payroll: labor cost in the books

Pay and compensation data from Greenhouse posts into Oracle Fusion ERP as labor cost, so finance sees workforce spend without re-entering it by hand.

How changes propagate between Greenhouse and Oracle Fusion ERP

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.

Greenhouse Oracle Fusion ERP Sub-second propagation

DetectionGreenhouse notifies Stacksync of record changes through webhook events. HMAC-SHA256 signed webhooks for candidate, application, job, and interview events, plus polling list endpoints with created_after / updated_after /.

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

Oracle Fusion ERP Greenhouse Interval-based propagation

DetectionStacksync polls Oracle Fusion ERP for changes on an incremental schedule, reading only records changed since the previous pass. Polling on last-updated attributes.

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

Rate-limit considerations

  • Greenhouse: Harvest enforces a per-integration limit over a rolling 10-second window (X-RateLimit-Limit, commonly 50 requests / 10s for approved integrations); responses carry X-RateLimit-Remaining and, on a 429, X-RateLimit-Reset and Retry-After.
