Oracle Fusion Cloud ERP and Dayforce integration

What moves between them

Employee records flow from Dayforce into Oracle Fusion Cloud ERP on a schedule tied to your payroll calendar. After each payroll cycle, Dayforce payroll reports are read and mapped to Fusion GL account codes and cost centers, then posted into Fusion's general ledger as labor cost journals. Employee status changes, terminations, and role updates in Dayforce are mirrored into Fusion so workforce counts and cost center allocations stay current. The Fusion general ledger is the system of record for accounting; no financial data flows back from Fusion to Dayforce.

How ml-connector handles it

ml-connector stores both credential sets encrypted and manages the Dayforce OAuth token lifecycle, including the one-hour expiry window and the daily client URL refresh requirement. On the Fusion side, it accepts the customer-specific pod URL and authenticates via OAuth 2.0 Client Credentials. Because both systems are poll-only, ml-connector polls Dayforce on a cadence aligned with your payroll schedule and Fusion on a matching cycle, reading only changed records using date-range filters. GL account mappings are validated against Fusion's chart of accounts before any journal is posted, so every payroll line references an account and cost center that already exist. ml-connector retries on transient failures and maintains a full audit trail of every employee record and GL posting so failed transactions can be replayed without duplication.

A real-world example

A mid-sized services company with offices across multiple regions runs Dayforce for payroll, benefits, and workforce scheduling, and Oracle Fusion Cloud ERP for general ledger and financial reporting. Before the integration, the finance team extracted payroll reports from Dayforce weekly, manually keyed the labor totals into Fusion journal batches, and spent the first week of each month reconciling headcount between Dayforce and Fusion payroll accounts. With Dayforce and Oracle Fusion Cloud ERP connected, each payroll cycle automatically flows labor costs into Fusion allocated to the correct cost centers and offices, and employee records stay in sync. Month-end close starts with payroll accounts already reconciled, eliminating the manual re-entry and the multi-day reconciliation process.

What you can do

• •Post Dayforce payroll GL postings into Oracle Fusion Cloud ERP's general ledger on your payroll schedule, allocated to the correct cost centers and GL accounts.
• •Keep Oracle Fusion Cloud ERP employee records aligned with Dayforce hires, terminations, role changes, and status updates.
• •Map Dayforce employee data to Fusion cost centers, departments, and GL account codes so payroll allocations land on valid accounts.
• •Authenticate Dayforce with OAuth 2.0 Resource Owner Password Credentials and manage the one-hour token expiry and daily client URL refresh.
• •Poll Dayforce and Oracle Fusion Cloud ERP on a schedule aligned with your payroll calendar, with retries and full audit trail on every record.

Questions

Which direction does data move between Oracle Fusion Cloud ERP and Dayforce?

Employee records and payroll GL postings move from Dayforce into Oracle Fusion Cloud ERP. Employee hires, terminations, and role changes sync from Dayforce to keep Fusion headcount current. Payroll journals post into Fusion's general ledger on your payroll cycle. GL account codes and cost centers are aligned in both directions so payroll allocations land on valid accounts. Fusion's general ledger is the system of record, so no financial data flows back to Dayforce.

How does ml-connector handle Dayforce's token expiry and URL refresh requirements?

Dayforce OAuth tokens expire in one hour and must be refreshed before expiry; ml-connector tracks token expiry and re-authenticates before each call to avoid failures. The Dayforce client-specific URL must be refreshed at least once per day, and ml-connector follows the daily refresh pattern to avoid redirect overhead. Both requirements are handled transparently so your payroll integration never breaks mid-cycle.

Does the integration require the Oracle Fusion Cloud ERP pod URL to be configured per customer?

Yes. Each customer's Fusion instance runs on a customer-specific pod and region, so ml-connector is configured with the full pod URL for authentication and REST API calls. Unlike some platforms with a shared base URL, Fusion publishes no shared hostname, so the pod URL is a required per-customer configuration. This allows the integration to work across all Fusion regions and deployment shapes.
