Import a candidate into Workday Recruiting via the Staffing web services SOAP API

Steps

1. Obtain your Workday tenant name, hostname, and an Integration System User (ISU) account with the Staffing functional area security policy permissions needed for candidate import.
2. The Workday Staffing WSDL is available at https://<hostname>/ccx/service/<tenant>/Staffing; download and generate client stubs or use a SOAP library.
3. Authenticate using WS-Security UsernameToken in the SOAP header, including the ISU username in the format ISU_name@tenant and the ISU password.
4. Use the Import_Candidate operation (or its equivalent in your Workday version) to submit candidate data including name, contact information, and source; map your fields to the Candidate_Data complex type.
5. Handle the response: on success, Workday returns a Candidate_Reference containing a WID (Workday ID); store this for subsequent operations like attaching the candidate to a job requisition.
6. For job application linking, use the Staffing web service operation to create a Candidate_Application referencing the WID and the Job_Requisition_Reference.
