Workday

This page records how composerID publishes into Workday: the vendor’s API posture, the publish target and field mapping, and the documentation each claim rests on. It is for anyone evaluating the connection or building against it. Workday is the worker and staffing system of record. composerID contracts contingent workers through the Staffing business-process operations; writes are largely SOAP-only, while reads are available via REST and RaaS.

Category: Vendor Management & Sourcing. Coverage status: Carrier mapped. Vendor documentation: public developer portal.

Integration path

How composerID connects to this destination, at a glance.

Step	Detail
Authentication	OAuth 2.0 (auth-code + ISU client-credentials) for REST; WS-Security or OAuth via an Integration System User (ISU) for SOAP.
composerID publishes	Contingent worker (contract): Contract_Contingent_Worker (Staffing SOAP BP)
Intent ID lands on	`job_requisition` `customObject.intentId`, written into the destination record
Carrier evidence	Cited: the vendor documents API-writable custom fields on this object; the field name is configured at onboarding. Source: Workday Recruiting: Edit_Job_Requisition_Additional_Data, checked 23 September 2026.
Back-sync	Polling: the destination publishes no events composerID can subscribe to, so state is read back on a schedule.

API posture

Aspect	Detail
Authentication	OAuth 2.0 (auth-code + ISU client-credentials) for REST; WS-Security or OAuth via an Integration System User (ISU) for SOAP. Access tokens ~1h; non-expiring refresh tokens configurable.
Style	SOAP (Workday Web Services: primary), REST/JSON (partial subset), RaaS (reports-as-a-service)
Base URL	REST https://{host}/ccx/api/{service}/v{n}/{tenant} \| SOAP https://{host}/ccx/service/{tenant}/{WebService}/v{n}
Webhooks	No native webhooks. Event-driven via the Business Process Framework, EIB outbound, Studio and Extend. RaaS is poll-based.
Events posture	Polling
Rate limits	Not officially published; practitioner ~10 req/s per tenant, HTTP 429 + Retry-After. Queue + exponential backoff.
Objects	Staffing (Create_Position, Contract_Contingent_Worker, End_Contingent_Worker_Contract), Job Requisition, Position, Worker, Supplier, Purchase Order

Publish target and field mapping

Each object below pairs the canonical intent fields with the destination’s own fields and operations. The mapping is indicative until it is confirmed against a tenant at onboarding.

Contingent worker (contract)

Onboard external worker

Mapping	Detail
Canonical to destination	worker, position, start_date, supplier, job_profile
Target	Contract_Contingent_Worker (Staffing SOAP BP)
Requirement	Required + tenant BP
Notes	Approvals run via the tenant business process

Position (create)

Create the headcount

Mapping	Detail
Canonical to destination	role_title, org, location, headcount
Target	Create_Position (Staffing SOAP)
Requirement	Required
Notes	Precedes contracting

End contract

Offboard / liveness

Mapping	Detail
Canonical to destination	worker_id, end_date, reason
Target	End_Contingent_Worker_Contract
Requirement	Required
Notes	Drives liveness + offboarding

Intent ID correlation

Carry the Intent ID

Mapping	Detail
Canonical to destination	intent_id, intent_version
Target	Integration reference ID / custom object field on the requisition
Requirement	Required
Notes	Reference IDs or a tenant custom object carry the correlation; confirmed per tenant

Pin a WWS version (e.g. v46.1) in every endpoint. Requires an ISU + integration security group + registered API client. Implementation and production tenants use different hosts.
