title: Facebook sdk for api marketing. Issue with v2.9
body: <p>I'm trying to get budget per day and started with getting list of campaigns.
  I followed the instructions here <a href="https://developers.facebook.com/docs/marketing-api/sdks" rel="nofollow noreferrer">https://developers.facebook.com/docs/marketing-api/sdks</a> , but when it reaches this line</p>
  
  <pre><code>$my_adaccount = $me-&gt;getAdAccounts()-&gt;current();
  </code></pre>
  
  <p>It says:
  Fatal error: Uncaught FacebookAds\Http\Exception\AuthorizationException: (#2635) You are calling a deprecated version of the Ads API. Please update to the latest version: v2.9. in /home/jane/projects/facebook/vendor/facebook/php-ads-sdk/src/FacebookAds/Http/Exception/RequestException.php:163</p>
  
  <p>So I updated to v2.9 but then it says that 
  FacebookAds\Object\AdUser is not found. I added this class and other missing classes from v2.5 and it worked.</p>
  
  <p>But there is another class missing, like <code>use FacebookAds\Object\AdCampaign;</code></p>
  
  <p>So the question is how can I install facebook sdk v2.9 with all classes, that needed? Like AdUser and AdCampaign?</p>
