RQM REST API - linked defects and TCR history

Use the "historyUrl" to get the history (of any resource in RQM actually, not just TCR).
https://jazz.net/wiki/bin/view/Main/RqmApi#historyUrl

The "calmlinks" parameter is also mentioned in the same document.

Here are other references to the "calmlinks" parameter. The difficult part is to figure out that the defect is part of the CALM integration.

found an answer to get defects included in reposnse - ?calmlinks-true at the end of URL. Still looking for a way to get TCR history.

thanks a lot Donald!

One additional question: what roles does user have to have to get response for history? I have my user set as tester, testlead, architect, testmanager, labmanager and still getting
"CRJAZ1316E The user \"CLOUDAS@xx.xxx.com\" does not have permission to read items that have the TeamArea access type."
