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).
Reports-as-a-Service (RaaS) Workday enables you to build your own web services through our Report Writer / Custom Reports functionality. When Custom Reports are web service enabled, they become Reports-as-a-Service (RaaS) and are exposed as both SOAP and REST-based web services for integration scenarios.
Workday REST API The Workday REST API is targeted for applications that do small, typically self-service, transactions initiated by users. Since a user initiates the interaction, the REST API is designed to quickly return a small set of frequently used information for display or further action.
