REST API For Approval State

I am trying to access information about an approval by leveraging the REST API. In particular, I am interested in finding out the state of a specific approval (not the aggregate value of a collection of approvals). I've been able to identify the REST command that will display the approvals with the names of the approvers associated with those approvals, but I have not identified the command to expose the state of the approval.

To find the name of the approver I am using:

Approvals/Approver/Name

According to this page https://jazz.net/wiki/bin/view/Main/ReportsRESTAPI, I should be able to drill down to find out information about an approval using these properties:

com.ibm.team.workitem.Approval

This element represents an approval from a single contributor with a particular state.

Properties:

• stateIdentifier (type: xs:string). The state of the approval
• stateDate (type: xs:time). The date the state was assigned
• stateName (type: xs:string). The name of the state
• approver (type: com.ibm.team.repository.Contributor). The contributor who is asked for approval
• approvalDescriptor (type: com.ibm.team.workitem.ApprovalDescriptor). The approval descriptor that aggregates the approval

However, this does not appear to be correct. I can get the approver so that works, but "stateIdentifier" doesn't work (although, "stateId" does). The remaining properties don't appear to work either. It looks like what I really need is the "stateName" command.

Does anyone know what the correct syntax is for this?
