title: Implementing a client-side WebHook handler?
body: <p>I am a bit of a newbie in Webhooks, so excuse me if this is a simple question.</p>
  
  <p>I am clear about how Webhook providers work, i.e. whenever this information needing to be pushed, it sends the payload to the URL specified as callback.</p>
  
  <p>Now my question is: how do I write a client-side Webhook handler, that can detect/process the callback and update my client-side accordingly. For example, if my client-side is a simple web-page with bullet-points, I would like to append new data to the list, whenever it comes through.</p>
  
  <p>Preferably, I would be after a complete JavaScript solution...</p>
  
  <p>Is there perhaps a JS WebHook Client/Handler that already exists? It seems that this should be so common, that it should exist, although I haven't been able to find anything.</p>
