title: Linkedin API search finder adCreatives
body: <p>I'm currently working with the LinkedIn marketing API in python and I'm migrating to the version 2.0.0.</p>
  <p>I was trying to get the <code>adCreatives</code> via <code>adCampaigns</code> urn in this way:</p>
  <pre><code>import requests
  
  url = 'https://api.linkedin.com/v2/adCreativesV2?q=search&amp;search=(campaigns:(values:List(urn%3li%3sponsoredCampaign%XXXXXXX, other_urns)))&amp;fields=campaign,id,reference,status,changeAuditStamps,type'
  
  response = request.request(url=url, headers={&quot;X-Restli-Protocol-Version&quot;: &quot;2.0.0&quot;,
                             &quot;Authorization&quot;: f&quot;Bearer {access_token}&quot;}, method=&quot;GET&quot;)
  </code></pre>
  <p>but I bumped into this error:</p>
  <pre><code>response.json()
  &gt;&gt;&gt; {'message': 'Request would return too many entities.', 'status': 400}
  </code></pre>
  <p>The first thing that I've tried was to reduce the amount of <code>adCampaigns</code> urn from the <code>List(...)</code> but because of I was still getting this error I've remove also all the parameters, but turns out it was pointless.</p>
  <p>The strange fact is that when I do the same API call with the following url</p>
  <pre><code>url = 'https://api.linkedin.com/v2/adCampaignGroupsV2?q=search&amp;search=(accounts:(values:List(urn%3li%3sponsoredAccount%XXXXX)))&amp;fields=account,id,name,status,changeAuditStamps,runSchedule
  </code></pre>
  <p>I get the correct response with the <code>status: 200</code>. This also happen with <code>adAccounts</code> and <code>adCampaigns</code>.</p>
  <p>Does anybody know how to solve this?</p>
