Steps
In Workday, create or locate an Advanced custom report and check the 'Enable As Web Service' option in the report's Advanced tab to expose it as a RaaS endpoint.
Navigate to the report's web service URL (found under Actions > Web Service > View URLs) — it follows the pattern https://{tenant}.workday.com/ccx/service/customreport2/{tenant}/{owner}/{report_name}.
Authenticate using Basic Auth (Integration System User credentials) or OAuth 2.0 Bearer token depending on your tenant configuration.
Append a format query parameter to the URL to control output: ?format=json for JSON, ?format=csv for CSV, or omit for the default XML response.
Parse the response; for JSON, data is nested under a Report_Entry array in the root object.
Known gotchas
RaaS only works with Advanced-type reports — Standard reports cannot be enabled as a web service; if the option is missing, check the report type first.
RaaS has no built-in pagination and runs the report in real time; very large reports may time out or exhaust memory — for high-volume data, consider Workday Query Language (WQL) or break the report into smaller filtered slices.
The report URL is tied to the owner's account; if that user is deactivated, the endpoint returns an error — use an Integration System User as the report owner to avoid this.
