title: whatsapp Chat-API fail [reason] => old_version
body: <p>Hello I am trying to get Whatsapp chat-api to work in php,<br>
  using the exampleRegister.php. I am trying to get the password from the server but it keeps giving me an error<br></p>
  
  <pre><code>=&gt; fail [reason] =&gt; old_version ) 
  Fatal error: Uncaught exception 'Exception' with message 'There was a problem trying to request the code.' in C:\xampp\htdocs\sendwhatsappmsg\Chat-API-master\Chat-API-master\src\Registration.php:316 Stack trace: #0 C:\xampp\htdocs\sendwhatsappmsg\Chat-API-master\Chat-API-master\examples\exampleRegister.php(41): Registration-&gt;codeRequest('sms') #1 {main} thrown in C:\xampp\htdocs\sendwhatsappmsg\Chat-API-master\Chat-API-master\src\Registration.php on line 316
  </code></pre>
  
  <p>I already tried to update it with composer and download multi files from Github<br>
  all of them seem to give this error not sure what am doing wrong or maybe this api no longer works <br>
  any help or tip will be welcome. <br>
  If anyone know other Whatsapp api  or better way to send msg from localserver/php to Whatsapp users please share :) </p>
