- **partnership required:** false
- **difficulty:** highly_complex
- **partnership note:** Apideck holds the Workday partnership; joining the Workday Partner Program yourself is optional.
- **important to know:** Permission setup differs per Unified API: the consumer's Workday admin grants domain security policies separately for HRIS (13+), ATS (11+) and Accounting (22+), plus Business Process Security Policy edits before any write succeeds.
Accounting writes are worktag-gated: invoices and purchase orders reject line items without a cost-center worktag (tracking_categories.id), and journal entries silently fall back to draft without one.
AP bills cannot be incrementally synced: Workday returns empty updated_at/created_at on Bills and rejects filter[updated_since] with an UnsupportedFiltersError, so plan full re-fetches.

- **apideck credentials note:** Authentication is per consumer rather than per application, so there are no app-level credentials for Apideck to provide.
- **consumer access level:** Administrator with privileges to create Integration System Users and manage security groups and domain security policies
- **difficulty reason:** Custom Auth + Manual Per-Consumer Setup + Complex Permissions
- **authentication note:** A per-consumer Integration System User (ISU); not OAuth.
- **partnership portal name:** Workday Partner Program
- **rate limits:** No published hard limits; Workday throttles under high tenant load.
- **sandbox note:** Testing runs against a consumer's own Workday tenant — no free trial, and Development tenants are contract-gated to existing Workday customers.
- **webhooks:** Virtual webhooks — no native webhooks in Workday; Apideck polls employees, applicants, jobs, bills, suppliers, purchase orders, and customers.
