Infor CloudSuite and Workday HCM integration

What moves between them

Workday workers and organizational structures flow into Infor CloudSuite as customer and supplier master records, synced daily or on demand. Cost center assignments in Workday map to GL account dimensions and cost center codes in Infor CloudSuite. Reference data such as organizations, positions, and compensation grades are aligned in both directions to keep payroll allocations in sync. The flow is read-only from Workday; ml-connector does not write worker or organizational data back to Workday.

How ml-connector handles it

ml-connector extracts OAuth credentials and the base URL from the Infor CloudSuite .ionapi file and constructs the tenant-specific endpoint per the ION Gateway pattern. It uses Infor's OAuth Resource Owner Password Credentials grant to fetch bearer tokens, proactively refreshing before the configured expiry (1 to 24 hours per tenant). On the Workday side, ml-connector stores both the SOAP UsernameToken credentials for financial APIs and the REST OAuth 2.0 refresh token, and automatically refreshes the REST access token before the 60-minute expiry. Organizations in Workday are mapped to customer or supplier segments in Infor CloudSuite using the organization code as a key. Cost center hierarchies and GL account strings are aligned so payroll journal lines reference valid dimensions. Both systems enforce rate limits, so ml-connector respects HTTP 429 responses with Retry-After headers and backs off exponentially. Every record carries a full audit trail and can be replayed if a downstream call fails.

A real-world example

A mid-sized professional services firm runs Infor CloudSuite Financials for accounting and project costing, and Workday HCM for workforce management, benefits, and expense tracking across five regional offices. Before the integration, the operations team maintained cost center codes and office codes in both systems by hand, and each month the payroll team exported labor allocations from Workday and re-entered them into Infor to close the books. With Infor CloudSuite and Workday HCM connected, new regional offices and cost centers sync automatically, employee assignments update when Workday changes them, and month-end payroll allocations flow straight into Infor for faster close cycles.

What you can do

• •Sync Workday workers and organizational assignments into Infor CloudSuite as customer and supplier dimension records daily or on demand.
• •Keep cost center hierarchies and GL account codes aligned across both systems so payroll allocations always reference valid dimensions.
• •Handle Infor's tenant-specific OAuth endpoints extracted from the .ionapi credentials file and Workday's SOAP and REST authentication separately.
• •Poll on a regular schedule with rate-limit awareness, exponential backoff on 429 responses, and proactive token refresh before expiry.
• •Track every record with a full audit trail and replay failed transactions without duplication or data loss.

Questions

Which direction do Workday and Infor CloudSuite data flow?

The main flow is from Workday into Infor CloudSuite. Workers, organizational structures, and cost center assignments move from Workday to Infor so the ERP reflects current HR dimensions. Reference data such as organizations and cost codes are aligned in both directions to keep them consistent. ml-connector does not write worker or organizational changes back into Workday.

Why does ml-connector need both SOAP and REST credentials for Workday?

Workday exposes worker and organizational data via REST with OAuth 2.0, but financial data such as GL accounts and cost centers requires SOAP with WS-Security UsernameToken authentication. ml-connector stores both credential sets encrypted and uses them on separate code paths depending on which resource is being read.

How does ml-connector handle Infor's tenant-specific OAuth endpoints?

Each Infor CloudSuite customer provides a .ionapi credentials file that contains the base URL, OAuth endpoints, tenant ID, and company number. ml-connector parses this file at connection setup, extracts the tenant-specific token endpoint, and uses it for all OAuth calls. This approach supports multi-region and multi-tenant deployments without hardcoding shared endpoints.
