title: How to get many issues with Jira REST API?
body: <p>New to REST API, and struggling a little.</p>
  <p>I learned recently from <a href="https://community.atlassian.com/t5/Jira-questions/How-to-get-Jira-issue-id-from-issue-key/qaq-p/1156675" rel="nofollow noreferrer">here</a> and <a href="https://community.atlassian.com/t5/Bitbucket-questions/REST-API-to-fetch-Jira-issue-id-of-a-particular-commit-in/qaq-p/1471382" rel="nofollow noreferrer">here</a> that I can receive a JSON describing an issue by calling a REST API of the form <code>&lt;JIRA_BASE_URL&gt;/rest/api/2/issue/{issueIdOrKey}</code>, e.g.:</p>
  <pre><code>curl -s -X GET -u super_user:super_password https://jira.server.com/rest/api/2/issue/TEST-12
  </code></pre>
  <p><strong>Is there a way I can query many issues at once if I have a list of issue-ids, e.g. <code>[&quot;TEST-12&quot;, &quot;TEST-13&quot;, &quot;TEST-14&quot;]</code>?</strong></p>
  <p>I'm specifically interested in getting the summary field of each issue in my list of issue-ids. I.e. I'm trying to create a map of <code>[issue-id:summary]</code>. I currently do this by invoking the above <code>curl</code> command in a loop for each issue-id in my list. But I observe that this takes a long time, and I wonder if performance might be improved if there's a way to do a &quot;bulk get&quot; -- if such a feature exists.</p>
