• built-in keys

    1) type: (String, required) One of "send", "publish", "register", "unregister".
    
    2) headers: (Object, optional) Headers with JSON format.
    
    3) body: (Object, optional) Message content in JSON format.
    
    4) address: (String, required) Destination address
    
    5) replyAddress: (String, optional) Address for replying to.

#include <stdio.h>
#include <stdlib.h>
#include "vertx/vertx.h"
