var url = 'https://pushalot.com/api/sendmessage'; 
var request = require('request');
request({
         'uri': url, 
         'method': 'post',
         'body' : "push",
         'AuthorizationToken=' : token,
         'headers' :{ 'content-Length' : data_lenght}                                                                   
        }
 ,function(error, response, body)
  {
        if (!error || response.statusCode == 200)
        {
          console.log("Push envoye : " + command);                                                                    
          callback({'tts' : body});                                                                          
        }
