title: infusionsoft api - how to get contact details by using contact id as filter
body: <p>I'm using the resthook feature of infusionsoft. The endpoint will return the <code>contact id</code> now I want to get full contact details using the id.</p>
  
  <pre><code>$contacts       = $infusionsoft-&gt;contacts()-&gt;load($contactid,$fields);
  </code></pre>
  
  <p>I'm using this as of the moment but it's not working. I tried this:</p>
  
  <pre><code>$contact = $infusionsoft-&gt;contacts()-&gt;where(['Id' =&gt; $contactid])-&gt;get();
  </code></pre>
  
  <p>but it is ignoring the where statement. </p>
  
  <p>I spent hours just to figure this out. </p>
