Sends a job order or shift request to WorkN and gets back a list of workers that would qualify as of that moment in time.
This endpoint does not create the job order or shift request. It serves as a means to retrieve a list of workers that would qualify for the job order or shift request if it is actually submitted to WorkN using the appropriate endpoints.
