title: Webhook + Server-side Authentication
body: <p>I have a user provide me the organization he wants to Sync with our system. We create the hooks afterwards for each App of the Organization.</p>
  
  <p>The only workaround I found is to ask for each App ID and Token or the username authentication.</p>
  
  <p>How can a Webhook be authentified to have the right to get items from all Apps at the same time? (like a server-side authentication)</p>
