Unable to create a job via REST

[Anonymous User]

Hi,

I am having problems attempting to create a job via a REST call; details below.  I can create job from workflow manger itself just not from a REST call.  We hold wmx sys tables in oracle db.  I'm also intrigued what if any user authentication can be applied against such a call given it would appear all that is required is a valid user with correct privildges to create a job. Any help appreciated.
