&gt; Want to download all the comments with the user info for every user? You have a choice between repeating the user info per comment, requesting the comments first then the users by id (two requests) or using a serialisation mechanism that supports object references (isn&#x27;t pure JSON)<p>Or you send it like<p><pre><code>    {
      &quot;users&quot;: [
        {
          &quot;id&quot;: &quot;de305d54-75b4-431b-adb2-eb6b9e546014&quot;,
          &quot;name&quot;: &quot;Max Mustermann&quot;,
          &quot;image&quot;: &quot;https:&#x2F;&#x2F;news.ycombinator.com&#x2F;y18.gif&quot;
        },
        ...
      ],
      &quot;comments&quot;: [
        {
          &quot;user&quot;: &quot;de305d54-75b4-431b-adb2-eb6b9e546014&quot;,
          &quot;time&quot;: &quot;2015-10-15T18:51:04.782Z&quot;,
          &quot;text&quot;: &quot;Or you can do this&quot;
        },
        ...
      ]
    }
</code></pre>
Which is a standard way to do it that works here, too. Because you can have references in JSON, you just have to do them yourself.
