Retrieve worker data from Workday via SOAP web services

Steps

1. Identify the correct Workday SOAP service WSDL, e.g. Human_Resources for worker data; the WSDL URL follows the pattern https://wd2-impl-services1.workday.com/ccx/service/TENANT/Human_Resources/vNN where vNN is the API version (e.g., v42.0).
2. Authenticate using an Integration System User (ISU) with WS-Security UsernameToken in the SOAP header; include the Workday tenant name prefixed to the username as TENANT#USERNAME.
3. Construct and send a Get_Workers SOAP request; use the Request_Criteria element to filter by worker type, hire date range, or specific worker references to limit payload size.
4. Parse the SOAP response envelope; worker data is nested under Response_Data/Worker elements, with Personal_Data, Employment_Data, and Organization_Data sub-elements varying by the Response_Filter.
5. Implement paging using the Response_Filter element with Page and Count fields; default page size is typically 100 workers per response.
