Agent pitfalls & tips
- Tenant URL is company-specific — no universal base URL.
- WQL (Workday Query Language) is powerful for custom data queries.
- ISSG permissions are granular — admin must configure per integration.
- SOAP API still dominant for complex operations — REST API growing.
- Test in sandbox tenant before production to avoid HR data issues.
