Why teams connect Greenhouse and Infor LN

Sync the workers, org structure, and cost centers that Infor LN 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. Infor LN 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 Warehouse / inventory, Projects, Service orders, Items in Infor LN with Scheduled Interviews, Users, Departments and Offices, Candidates 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 Infor LN 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 Run a two-way sync of business partners between LN and a CRM so sales and manufacturing share account data.
  • 02 Keep inventory positions aligned between LN and distribution or aftermarket service systems.
  • 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.

Common sync patterns

Where Greenhouse runs payroll: labor cost in the books

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

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 Infor LN is created, updated, or deactivated, so the business system reflects the workforce as it actually is.

New hires ready to transact in Infor LN

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

What you can sync between Greenhouse and Infor LN

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.

Greenhouse objects Infor LN objects How this pairing syncs
Offers Offer records tied to an Application with status and custom offer fields; readable and patchable, commonly synced to HRIS on hire. Projects Project structures used in engineer-to-order manufacturing scenarios. Offers is specific to Greenhouse and Projects to Infor LN — each maps to any object or custom field on the other side.
Scorecards Interviewer feedback and ratings tied to interviews; read-only in Harvest, exported to a warehouse for interview analytics. Service orders Aftermarket service documents synced with field service tools. Scorecards is specific to Greenhouse and Service orders to Infor LN — each maps to any object or custom field on the other side.
Scheduled Interviews Interview events with interviewers, times, and rooms; full create/update/delete support for calendar and reporting syncs. Items Manufacturing item masters synced to PLM, MES, and commerce systems. Scheduled Interviews is specific to Greenhouse and Items to Infor LN — each maps to any object or custom field on the other side.
Users Greenhouse users (recruiters, hiring managers); read and written, and referenced by the On-Behalf-Of header on every write. Bills of material Product structures shared with engineering and planning tools. Users is specific to Greenhouse and Bills of material to Infor LN — each maps to any object or custom field on the other side.
Departments and Offices Org structure attached to Jobs; read and written to keep reporting hierarchies aligned with an HRIS or warehouse. Business partners LN's unified customer/supplier records matched against CRM accounts. Departments and Offices is specific to Greenhouse and Business partners to Infor LN — each maps to any object or custom field on the other side.
Candidates Person records with contact details, tags, and custom fields; read and written via Harvest, often created from sourcing or enrichment pipelines. Sales orders Demand documents synced in from EDI and commerce channels. Candidates is specific to Greenhouse and Sales orders to Infor LN — each maps to any object or custom field on the other side.

How changes propagate between Greenhouse and Infor LN

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 Infor LN 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 Infor LN through its API, with automatic retries and rate-limit backoff.

Infor LN Greenhouse Interval-based propagation

DetectionStacksync polls Infor LN for changes on an incremental schedule, reading only records changed since the previous pass. Event-style BOD publications through Infor ION where configured.

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.
  • Infor LN: Subject to the ION API gateway's tenant rate limits in cloud deployments.
