Why teams connect Extensiv (3PL Central) and Greenhouse

Sync the workers, org structure, and cost centers that Extensiv (3PL Central) 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. Extensiv (3PL Central) 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 Inventory adjustments, Customers, Items, Inventory in Extensiv (3PL Central) with Applications, Jobs, Offers, Scorecards 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 Extensiv (3PL Central) 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 commerce or ERP orders into 3PL Central for fulfillment, and sync shipment confirmations with tracking numbers back.
  • 02 Keep item masters aligned between a merchant's ERP and the 3PL warehouse so receiving and picking use consistent SKUs.
  • 03 Export Scorecards and Scheduled Interviews to a data warehouse to analyze interviewer load and interview outcomes.
  • 04 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.

Rate-limit considerations

  • Extensiv (3PL Central): Subject to the platform's API rate limits; batch endpoints reduce call volume for order and inventory syncs.
  • 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.
