Why teams connect Greenhouse and Unleashed Software

Sync the workers, org structure, and cost centers that Unleashed Software 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. Unleashed Software 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 Bills of Materials, Invoices, Products, Stock On Hand in Unleashed Software with Departments and Offices, Candidates, Applications, Jobs 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 Unleashed Software 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 Sync Customers bi-directionally with a CRM so credit terms and delivery addresses match everywhere.
  • 02 Sync Stock On Hand into an ecommerce platform or CRM so quotes and listings reflect real availability.
  • 03 Stream Jobs, Departments, and Offices into a reporting database for recruiting funnel and time-to-fill dashboards.
  • 04 Export Scorecards and Scheduled Interviews to a data warehouse to analyze interviewer load and interview outcomes.

Common sync patterns

Where Greenhouse is the worker system of record: one employee master

When a worker is hired, moved, or offboarded in Greenhouse, the matching employee record in Unleashed Software is created, updated, or deactivated, so the business system reflects the workforce as it actually is.

New hires ready to transact in Unleashed Software

A new person set up in Greenhouse becomes an employee record in Unleashed Software in time to submit expenses, enter time, or approve a purchase, without waiting on manual setup.

One org structure

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

How changes propagate between Greenhouse and Unleashed Software

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 Unleashed Software 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 Unleashed Software through its API, with automatic retries and rate-limit backoff.

Unleashed Software Greenhouse Interval-based propagation

DetectionStacksync polls Unleashed Software for changes on an incremental schedule, reading only records changed since the previous pass. Polling with modified-date filters on list endpoints.

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.
  • Unleashed Software: Subject to the platform's API rate limits; paginate list endpoints and batch where possible.
