What is WhatsApp?

According to the company:

WhatsApp Messenger is a cross-platform mobile messenger that replaces SMS and works through the existing internet data plan of your device. WhatsApp is available for iPhone, BlackBerry, Android, Windows Phone, Nokia Symbian60 & S40 phones. Because WhatsApp Messenger uses the same internet data plan that you use for email and web browsing, there is no cost to message and stay in touch with your friends.

Late 2011 numbers: 1 billion messages per day, ~20 million users.

Modified XMPP

WhatsApp uses some sort of customized XMPP server, named internally as FunXMPP, which is basically some extended proprietary version.

Login procedure

Much like XMPP, WhatsApp uses JID (jabber id) and password to successfully login to the service. WhatsApp has recently deprecated using IMEI/MAC to generate the account's.

Message sending

Messages are basically sent as TCP packets, following WhatsApp’s own format (unlike what’s defined in XMPP RFCs).
Despite the usage of SSL-like communication, messages are being sent in plain-text format.

Multimedia Message sending

Photos, Videos and Audio files shared with WhatsApp contacts are HTTP-uploaded to a server before being sent to the recipient(s) along with Base64 thumbnail of media file (if applicable) along with the generated HTTP link as the message body.

3. Once you have done this you can send messages from admin/config/services/whatsapp/test or any other way available.
