Why teams connect Ceridian Dayforce and Infor LN

Sync the workers, org structure, and cost centers that Infor LN and Ceridian Dayforce share in real time, so the people Ceridian Dayforce manages stay current in the system that runs finance and operations.

Ceridian Dayforce 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 Service orders, Items, Bills of material, Business partners in Infor LN with Work Assignments, Compensation Summary & Pay Adjustments, Employee Punches & Raw Clock Entries, Employee Schedules in Ceridian Dayforce 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 Flow EDI and ecommerce sales orders into LN and return order status and shipment confirmations.
  • 02 Replicate LN data into a warehouse for production, OTIF, and supply chain reporting.
  • 03 Replicate Compensation Summary and pay data into a warehouse for headcount, labor-cost, and compensation reporting without manual BI exports.
  • 04 Sync time data by posting raw clock entries from a third-party scheduling tool into Dayforce, or pulling Employee Punches and Schedules into a workforce-analytics database.

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 Infor LN roll up to the same structure Ceridian Dayforce maintains.

Reporting lines drive approvals

Manager and reporting-hierarchy changes in Ceridian Dayforce keep expense and purchase approval chains in Infor LN pointed at the right people.

Where Ceridian Dayforce runs payroll: labor cost in the books

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

What you can sync between Ceridian Dayforce 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.

Ceridian Dayforce objects Infor LN objects How this pairing syncs
Employee (HR / Person Details) Core worker record keyed by XRefCode; GET Employees returns matching XRefCodes, then a per-employee GET fetches full HR details. New hires are added with POST and edits made with PATCH, so it is read and write. Bills of material Product structures shared with engineering and planning tools. Employee (HR / Person Details) is specific to Ceridian Dayforce and Bills of material to Infor LN — each maps to any object or custom field on the other side.
Employment Status Effective-dated employment status and type (active, leave, terminated) that drives active/terminated state for downstream provisioning; read, and writable as new dated status records. Business partners LN's unified customer/supplier records matched against CRM accounts. Employment Status is specific to Ceridian Dayforce and Business partners to Infor LN — each maps to any object or custom field on the other side.
Work Assignments Effective-dated position, department, location, and org-unit assignment; the most-synced record for org charts, provisioning, and analytics. Read and updatable via PATCH. Sales orders Demand documents synced in from EDI and commerce channels. Work Assignments is specific to Ceridian Dayforce and Sales orders to Infor LN — each maps to any object or custom field on the other side.
Compensation Summary & Pay Adjustments Compensation Summary returns pay rate and frequency for reporting; Employee Pay Adjustments are written as effective-dated records via PATCH to post pay changes back to Dayforce. Purchase orders Supply documents shared with supplier and procurement systems. Compensation Summary & Pay Adjustments is specific to Ceridian Dayforce and Purchase orders to Infor LN — each maps to any object or custom field on the other side.
Employee Punches & Raw Clock Entries Time-and-attendance punches; raw clock entries are added with POST and punches removed with DELETE, so time data flows both ways between Dayforce and scheduling or workforce tools. Production orders Shop-floor work orders synced with MES for execution visibility. Employee Punches & Raw Clock Entries is specific to Ceridian Dayforce and Production orders to Infor LN — each maps to any object or custom field on the other side.
Employee Schedules Shift and schedule assignments; created and updated through POST and PATCH schedule endpoints and paged with pageSize, used to push schedules from a WFM tool or pull them for analytics. Warehouse / inventory Stock positions exposed so external channels reflect real availability. Employee Schedules is specific to Ceridian Dayforce and Warehouse / inventory to Infor LN — each maps to any object or custom field on the other side.

How changes propagate between Ceridian Dayforce 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.

Ceridian Dayforce Infor LN Sub-second propagation

DetectionCeridian Dayforce notifies Stacksync of record changes through webhook events. No CDC stream.

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

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

Rate-limit considerations

  • Ceridian Dayforce: Dayforce does not publish numeric rate limits; thresholds vary by tenant and exceeding them returns HTTP 429, so large employee reads are paged (pageSize) and throttled with backoff. Employee list calls return XRefCodes only, so each employee needs a follow-up GET.
  • Infor LN: Subject to the ION API gateway's tenant rate limits in cloud deployments.

How the Ceridian Dayforce and Infor LN connectors work

Ceridian Dayforce

Integration surface
REST API (Dayforce RESTful Web Services, v1/v2), JSON payloads
Authentication
HTTP Basic authentication with a dedicated Web Services user plus the client namespace (Company ID), or an OAuth 2.0 access token from the Dayforce identity endpoint (POST dfid.dayforcehcm.com/connect/token, client_id Dayforce.HCMAnywhere.Client). Token-based auth is recommended, and the Web Services role with the Read Data subfeature must be enabled on the account.
Change detection
No CDC stream. Broad change detection uses delta polling on GET Employees with filterUpdatedStartDate/filterUpdatedEndDate and filterUpdatedEntities to pull only records changed in a window. Dayforce also has native Event Notifications (the Notification Publisher) for lifecycle events — hire, rehire, terminate, and workflow validation — delivered by push to a receiver service or by querying unacknowledged notifications; the publisher runs roughly hourly and each notification must be acknowledged.
