Why teams connect Ceridian Dayforce and Lemlist
Keep the people, teams, and status that Lemlist and Ceridian Dayforce share aligned in real time, so a hire, role change, or departure recorded in one reaches the other within seconds.
Each tool in Lemlist keeps its own list of who can use it: users, members, or agents, along with the team they sit on and whether they are still active. Ceridian Dayforce is the authoritative record of the same people as employees, with their department, manager, and employment status. When those two are connected only by manual account admin or a periodic export, the work tools drift: new hires wait days for access, team and manager changes never catch up, and people who have left keep standing accounts.
Stacksync syncs Leads, Activities, Unsubscribes, Webhooks in Lemlist with Employee Punches & Raw Clock Entries, Employee Schedules, Org Units, Departments, Jobs & Positions, Time Away From Work & Balances in Ceridian Dayforce bi-directionally and in real time. A person added, moved, or offboarded in Ceridian Dayforce creates or updates the matching user in Lemlist within seconds, with field-level mapping and conflict resolution in place of spreadsheets and one-off account changes. Where Lemlist captures details of its own, such as a corrected contact or a login identity, those can flow back to Ceridian Dayforce in whichever direction you configure.
Because the sync is field-level, each system keeps its own extras; only the shared facts, who a person is, which team they belong to, and whether their access should be on, are held in agreement.
Common use cases
- 01 Sync replies, opens, and bounces from Lemlist into the CRM so outbound activity shows on lead and contact records
- 02 Push enriched leads from a warehouse or list-building workflow into Lemlist campaigns automatically
- 03 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.
- 04 Push new hires (Employee, Employment Status, Work Assignment) from an ATS or onboarding tool into Dayforce with POST once a candidate is hired, pre-fetching valid XRefCodes for department, position, location, and pay group.
Common sync patterns
Offboarding: no standing access after a departure
When someone is marked as leaving in Ceridian Dayforce, the matching account in Lemlist is deactivated or flagged, so departures do not leave open access behind.
One employee directory
A person's name, title, contact details, or status corrected in either system updates the other, so both sides stop maintaining separate copies of the same person.
Org and team structure kept current
Department, team, and reporting-line changes from Ceridian Dayforce keep the groups, queues, or projects in Lemlist assigned to the right people.
What you can sync between Ceridian Dayforce and Lemlist
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 | Lemlist objects | How this pairing syncs | |
|---|---|---|---|
| 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. | Campaigns Outreach campaigns are the container leads are pushed into from CRMs and list-building workflows. | Employment Status is specific to Ceridian Dayforce and Campaigns to Lemlist — 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. | Leads Per-campaign prospect records sync in from enrichment sources and back out with status. | Work Assignments is specific to Ceridian Dayforce and Leads to Lemlist — 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. | Activities Engagement records such as opens, clicks, replies, and bounces sync to CRM timelines. | Compensation Summary & Pay Adjustments is specific to Ceridian Dayforce and Activities to Lemlist — 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. | Unsubscribes Opt-out records propagate to other outreach tools and the CRM for compliance. | Employee Punches & Raw Clock Entries is specific to Ceridian Dayforce and Unsubscribes to Lemlist — 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. | Webhooks Hook subscriptions define which activity events are pushed to external endpoints. | Employee Schedules is specific to Ceridian Dayforce and Webhooks to Lemlist — 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. | Team Members Sender and seat records map outreach activity to reps in other systems. | Org Units, Departments, Jobs & Positions is specific to Ceridian Dayforce and Team Members to Lemlist — each maps to any object or custom field on the other side. |
How changes propagate between Ceridian Dayforce and Lemlist
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.

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.
- Lemlist: Subject to the platform's API rate limits.

How the Ceridian Dayforce and Lemlist 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.

FAQ
Ceridian Dayforce and Lemlist integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Ceridian Dayforce and Lemlist: authenticate both systems, choose the objects to sync (such as Ceridian Dayforce's Employment Status and Work Assignments), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
Lemlist: Lemlist's data model attaches leads to campaigns, so cross-campaign views of a prospect are assembled by the consuming system rather than provided natively, which makes CRM sync the practical system of record. Ceridian Dayforce: Auth is HTTP Basic (Web Services user plus client namespace) or an OAuth 2.0 token from dfid.dayforcehcm.com/connect/token; Dayforce does not publish numeric rate limits and returns HTTP 429 when a tenant's throttle is exceeded. Stacksync's field mapping accounts for these differences between Ceridian Dayforce and Lemlist without custom code.
-
Stacksync is SOC 2 Type II and ISO 27001 certified with HIPAA BAA support. Data is encrypted in transit, and a zero-persistent-storage architecture means Ceridian Dayforce and Lemlist records are not retained after a sync operation.
-
Stacksync pricing is usage-based and starts at $1,000/month, including the managed Ceridian Dayforce and Lemlist connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom Ceridian Dayforce–Lemlist integration in-house.
