Latest WWS API Documentation Directory

API Type Description
Public Web Services API Directory Workday offers an open, standards-based SOAP API for programmatic access to our On-Demand Business Management Services. The following directory provide the API Documentation for our multi-tenant SOAP-based web services with corresponding WSDL and XML Schemas (XSD's).
(Preview) Public Web Services API Directory 

This directory provides the API Documentation for our Preview tenants' SOAP-based web services with corresponding WSDL and XML schemas (XSDs).

Preview tenants may contain more than one preview version. Preview versions can change at service updates, so you may need to retrieve the latest WSDL if your use of a production version spans a service update.

Consult the Workday Web Services Version Schedule to find out if a version has changed from preview to production.
