Hi ,

Could you please check the user is having the permission to trigger Oozie in Ranger policy (OR) also please check your Oozie workflow xml file is present in HDFS path once ..

Normal Basic Auth is fine for accessing Oozie REST APIs ..I am able to perform POST and GET request of Oozie workflow successfully and monitor the status of the workflow in the same script .
