  <p>Now I want to get value of "id". I have used <a href="https://pypi.python.org/pypi/jsonpath-rw" rel="nofollow">jsonpath-rw library</a> for Python, but that is not working. If I use <code>*</code> whole response gets printed. Looks like the whole response is root. I have used different combinations on <a href="http://jsonpath.curiousconcept.com/" rel="nofollow">http://jsonpath.curiousconcept.com/</a>, such as <code>*.id</code>, <code>$[0].id</code>.</p>
