title: WhatsApp url scheme for iPhone app
body: <p>We are developing an iPhone app and planning to integrate Whatsapp.</p>
  
  <p>Is there a way to enable click to call / message from the iPhone app? Skype allows this by following:</p>
  
  <pre><code>&lt;a href="skype:skypehandle?call"&gt; Skype &lt;/a&gt;
  </code></pre>
  
  <p>Is there an equivalent for Whatsapp ?</p>
