How to retrieve Custom Attribute identifier from ETM

Answer

1. Create an artifact in the ETM Web UI in the project you will be importing artifacts into and of the same kind (for example a Test Case).
2. Enter values for the custom attributes the identifiers of which you want to retrieve and save the artifact
3. Download the project feed from 
   https://<server:port>/qm/service/com.ibm.rqm.integration.service.IIntegrationService/resources/projects
4. Find your project area by name in the feed
5. Find the project alias of the project area in the feed.
6. Install a REST client like the RQMURL utility or the RESTer browser plug-in.
7. Perform a GET call for the artifact created in step 1 using the URL 
   https://<server:port>/qm/service/com.ibm.rqm.integration.service.IIntegrationService/resources/<project-alias>/<artifact-type>/<artifact-type-urn>:<artifact-id>
   For example
   https://localhost:9443/qm/service/com.ibm.rqm.integration.service.IIntegrationService/resources/JKE+Banking+%28Quality+Management%29/testcase/urn:com.ibm.rqm:testcase:32
    
   • If you are using RQMUrlUtility Execute the command 
     
     java.exe -jar RQMUrlUtility.jar  -command GET  -user user  -password user  -filepath <file-path> -url <artifact-url>
   • If you are using RESTer select Method: GET and add the header Accept: text/xml
8. Open the XML response in an XML editor
9. Search for the XML tag that says customAttribute
   
   <ns4:customAttributes>
   <ns4:customAttribute required="true" type="SMALL_STRING">
   <ns4:identifier>myId</ns4:identifier>
   <ns4:name>myId</ns4:name>
   <ns4:value>myValue</ns4:value>
   <ns4:description />
   </ns4:customAttribute>
   </ns4:customAttributes>
    
   The tag <ns4:identifier> contains the identifier.
