let body = {

  "notification": {

     "title": "IONIC NOTIFIFCATION",

     "body": "NOTIFICATION title :" ,

     "sound": "default",

     "vibrate": "true",

};
let header: HttpHeaders = new HttpHeaders();

header = header.set(‘Authorization’, appKEY);

header = header.append(“Content-Type”, “application/json”);
