title: Nativescript send message through WhatsApp
body: <p>I am developing a NativeScript Android application in which I want the user to be able to open a WhatsApp contact after pressing a button (only phone number is known). I currently use  <a href="https://www.npmjs.com/package/nativescript-open-app" rel="nofollow noreferrer">Nativescript-open-app</a> to open WhatsApp. Is it possible to also open the conversation? </p>
  
  <p>To open WhatsApp I use the following code (maybe it's possible by altering "com.whatsapp"?):</p>
  
  <pre><code>var openApp = require("nativescript-open-app").openApp;
  var installed = openApp("com.whatsapp");
  </code></pre>
  
  <p>Any help is welcome, thank you!</p>
