title: HTML link for add contact to whatsapp
body: <p>I need to put a deep link in my HTML for adding a contact to the Phone and then begin a new conversation in whatsapp.</p>
  
  <p>I found this code</p>
  
  <pre><code>&lt;a href="whatsapp://send?text=Hello%2C%20World!"&gt;Send text to whatsapp&lt;/a&gt;
  </code></pre>
  
  <p>And this one:</p>
  
  <pre><code>&lt;a href="whatsapp://send?abid=username&amp;text=Hello%2C%20World!"&gt;Send text to user&lt;/a&gt;
  </code></pre>
  
  <p>I need to open a conversation with a specific contact even if I don't have the contact. My first question is, where can I get the username for whatsapp?</p>
  
  <p>Having the abid I can try if it works but I dont know where to get that data.</p>
  
  <p>Thanks a lot</p>
