title: Send bulk message using WhatsApp API using PHP
body: <p>I have implemented WhatsApp message system via web using <a href="https://github.com/mgp25/WhatsAPI-Official" rel="nofollow">this</a> API now i can send <code>text</code> <code>image</code> and <code>video</code> message to some WhatsApp contacts without using a phone. However can I use this api for bulk messaging through WhatsApp? that means can i use it for production purpose?</p>
