title: Pull parent projects and Set Page Size Rally API
body: <p>1.
              I am creating a dashboard for seeing status for all Rally teams. I made an API call which gave me the user stories. But that does not fetch all user stories. So, how to set page size for this url. I tried but it doesn't work.</p>
  
  <pre><code>url     = "https://rally1.rallydev.com/slm/webservice/v2.0/hierarchicalrequirement?query=((Project.Name%20%3D%20%22" + teamNameEncoded + "%22)%20and%20(Iteration.Name%20%3D%20%22Sprint%20" + key['sprintNumber'] + "%20" + key['sprintEndDate'] + "%22))&amp;fetch=Name,FormattedID,PlanEstimate"
  </code></pre>
  
  <p>How to add a pageSize parameter in this url? </p>
  
  <ol start="2">
  <li>How to fetch parent projects from the Rally using the above API call?
  The above API calls fetches only child projects as per the output. But I am not specifying anything to fetch child projects also. So, I need to fetch parent projects also.</li>
  </ol>
  
  <p>Thanks In Advance.</p>
