You can use this workflow to connect to a KNIME Server, list the your jobs and select which ones you wish to permanently delete. For very large numbers of jobs you may need to increase the timeout in the GET Request node. The workflow can be run from any KNIME Analytics Platform that has access to a KNIME Server, or as a WebPortal application on a KNIME Server. Be sure to specify the KNIME Server address including the trailing slash e.g. https://localhost/
