Why teams connect Extensiv (3PL Central) and Lever

Sync the workers, org structure, and cost centers that Extensiv (3PL Central) and Lever share in real time, so the people Lever manages stay current in the system that runs finance and operations.

Lever 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 Customers, Items, Inventory, Orders in Extensiv (3PL Central) with Notes and Contacts, Opportunities, Postings, Requisitions in Lever 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 Push receiving confirmations back to purchasing systems when inbound stock arrives.
  • 02 Consolidate order and shipment data across 3PL clients into a reporting database for billing and SLA tracking.
  • 03 Write enriched Sources, Tags, and Contact data back onto Opportunities from an outbound sourcing pipeline.
  • 04 Two-way sync Opportunities and their Stages between Lever and a Postgres database so recruiting ops and analysts query the pipeline in SQL while recruiters keep working in Lever.

Common sync patterns

Inventory On-hand and available quantities by warehouse, mirrored out to drive channel availability. Opportunities The core pipeline record for a candidate applying to a role; replaced the deprecated Candidates endpoint. Created via POST /opportunities and updated (stage, archive, links, tags, sources, files) through the API, and synced two-way with a database or HRIS. Inventory is specific to Extensiv (3PL Central) and Opportunities to Lever — each maps to any object or custom field on the other side.

Receivers Inbound receiving records (receipts/ASNs) that confirm stock arrival back to purchasing systems. Requisitions Headcount/requisition records with custom requisition fields, tied to Postings; read via GET /requisitions and synced to an HRIS to reconcile approved headcount against open roles. Receivers is specific to Extensiv (3PL Central) and Requisitions to Lever — each maps to any object or custom field on the other side.
Shipments Carrier and tracking details synced back once orders ship. Offers Offer records attached to an Opportunity with status and offer-form fields; exposed read-only through GET /opportunities/:id/offers, so they sync outbound to an HRIS or onboarding system when a candidate reaches the offer stage. Shipments is specific to Extensiv (3PL Central) and Offers to Lever — each maps to any object or custom field on the other side.

How changes propagate between Extensiv (3PL Central) and Lever

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.

Extensiv (3PL Central) Lever Sub-second propagation

DetectionExtensiv (3PL Central) notifies Stacksync of record changes through webhook events. Webhook events for order, receipt, item, and inventory changes, with polling on modified-date filters as a fallback.

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

Rate-limit considerations

  • Extensiv (3PL Central): Subject to the platform's API rate limits; batch endpoints reduce call volume for order and inventory syncs.
  • Lever: 10 requests/second per API key with a token-bucket burst to ~20/s; POSTs that create candidates/applications are throttled to roughly 2/second. Sustained overage returns 429 with Retry-After. List endpoints are cursor-paginated at up to 100 records per page.
