title: Asana API Sync Error
body: <p>I currently have a application running that passes data between Asana and Zendesk.</p>
  
  <p>I have webhooks created for all my Project in Asana and all project events are sent to my webhook end point that verifies the request and tries to identify the event and update Zendesk with relevant data depending on the event type (Some events aren't required).</p>
  
  <p>However I have been receiving the following request from the Webhooks just recently:</p>
  
  <pre><code>  "events": [
       {
        "action": "sync_error",
        "message": "There was an error with the event queue, which may have resulted in missed events. If you are keeping resources in sync, you may need to manually re-fetch them.",
        "created_at": "2017-05-23T16:29:13.994Z"
      }
    ]
  </code></pre>
  
  <p>Now because I don't poll the API for event updates I react when the events arrive with me, I haven't considered using a Sync key, the docs suggest this is only required when polling for events. Do I need to use one when using Webhooks also?</p>
  
  <p>What am I missing?</p>
  
  <p>Thanks in advance for any suggestions.</p>
