title: GetResponse API v3: GET /contacts does not return all contacts
body: <p>Although adding contacts via the API (POST /contacts) works fine, i don't get all active Contacts using GET /contacts (see <a href="https://apidocs.getresponse.com/v3/resources/contacts" rel="nofollow noreferrer">https://apidocs.getresponse.com/v3/resources/contacts</a>).</p>
  
  <pre><code>public function getContacts()
  {
      return $this-&gt;get('contacts', [
          'query' =&gt; [
              'campaignId' =&gt; $this-&gt;campaign
          ],
          'fields' =&gt; 'name,email',
          'perPage' =&gt; $this-&gt;perPage
      ]);
  }
  </code></pre>
  
  <p>How can i fix it?</p>
