Why teams connect Ceridian Dayforce and Seismic
Keep the people who own accounts in Seismic in step with the workforce records in Ceridian Dayforce, so ownership, roles, and org structure stay current in both systems, in real time and in both directions.
Seismic runs on people as much as on accounts: every contact, deal, and account has an owner, and those owners are employees whose roles, teams, and status are held in Ceridian Dayforce. Ceridian Dayforce is the system of record for the workforce, from new hires to promotions to departures, and often for the candidates the business is still deciding on. When the two systems are connected only by re-keying or an overnight export, they drift apart, and the CRM ends up assigning accounts to people who have left, holding territories that no longer match the org chart, and waiting days to give a new rep access.
Stacksync syncs Library Content, Content Versions, Users, User Groups in Seismic with Time Away From Work & Balances, Employee (HR / Person Details), Employment Status, Work Assignments in Ceridian Dayforce field by field, in real time, and in both directions. You decide which system owns which fields, so Ceridian Dayforce stays authoritative on roles and org structure while Seismic keeps ownership and territory current, and Stacksync resolves conflicts by the rules you set.
Common use cases
- 01 Provision and deactivate Seismic Users and User Groups from an HRIS or IdP so content access mirrors joiner, mover, and leaver changes.
- 02 Extract content-interaction and LiveSend engagement from the Reporting API v2 into a warehouse to tie asset views to CRM Opportunities.
- 03 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.
- 04 Two-way sync of Employee and Work Assignment data (position, department, location, org unit) into Postgres so provisioning, internal apps, and analytics read current worker and org data in SQL while HR keeps editing in Dayforce.
Common sync patterns
Ownership and territory follow the org chart
When a person changes team, manager, or region in Ceridian Dayforce, their accounts and territory assignments in Seismic update to match, so pipeline stays with the right owner.
Deactivate access when someone leaves
When Ceridian Dayforce marks a worker as departed, the matching user in Seismic is flagged or deactivated, so former employees do not keep CRM access after their last day.
One directory of people
A person's name, title, email, phone, or manager corrected in either system updates the other, so both stop maintaining separate copies of the same individual.
What you can sync between Ceridian Dayforce and Seismic
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 | Seismic objects | How this pairing syncs | |
|---|---|---|---|
| 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. | Users User records managed through SCIM 2.0 and legacy user endpoints; created, updated, and deactivated for provisioning sync. | Employee Schedules is specific to Ceridian Dayforce and Users to Seismic — each maps to any object or custom field on the other side. | |
| Org Units, Departments, Jobs & Positions Configuration reference data; POST creates org units and departments and PATCH updates job, position, department, and org-unit data. Used to resolve and validate XRefCodes when mapping employee writes. | User Groups Group definitions and membership that govern content access; synced from an IdP or HRIS to keep permissions current. | Org Units, Departments, Jobs & Positions is specific to Ceridian Dayforce and User Groups to Seismic — each maps to any object or custom field on the other side. | |
| Time Away From Work & Balances Time-off requests and accrual balances read per employee; pulled into scheduling, payroll, or absence-reporting databases and used to reconcile leave against downstream systems. | Teamsites Tenant-scoped workspace partitions organizing Library content, permissions, and config; scoped by teamSiteId on most content calls. | Time Away From Work & Balances is specific to Ceridian Dayforce and Teamsites to Seismic — each maps to any object or custom field on the other side. | |
| 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. | LiveSend Links Trackable content-share links created via the engagement API; their open and view engagement is read back through Reporting. | Employee (HR / Person Details) is specific to Ceridian Dayforce and LiveSend Links to Seismic — 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. | Digital Sales Rooms Buyer-facing microsites (DSRs); lifecycle and content-change events surface via webhooks, currently marked Early Access. | Employment Status is specific to Ceridian Dayforce and Digital Sales Rooms to Seismic — 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. | Reporting Activities Content-interaction, engagement, and usage analytics extracted read-only through the ETL-oriented Reporting API v2 for a warehouse. | Work Assignments is specific to Ceridian Dayforce and Reporting Activities to Seismic — each maps to any object or custom field on the other side. |
How changes propagate between Ceridian Dayforce and Seismic
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 Seismic Sub-second propagation
DetectionCeridian Dayforce notifies Stacksync of record changes through webhook events. No CDC stream.
DeliveryEach detected change is written to Seismic through its API, with automatic retries and rate-limit backoff.
Seismic Ceridian Dayforce Sub-second propagation
DetectionSeismic notifies Stacksync of record changes through webhook events. Webhooks for content, version, user, group, workflow, DSR, and LiveSend events.
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.
- Seismic: Tiered per-endpoint limits over a rolling 60-second window; exceeding returns HTTP 429, with X-Seismic-Remaining-Calls and X-Seismic-Total-Calls headers.

How the Ceridian Dayforce and Seismic 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.
