 *  https://blynk.cloud/external/api/logEvent?token=YourAuthToken&code=hello for loging the events using rest API

 *  You can send only 100 events per devices per day

    When the limit is reached you'll see the notification on the UI in the Device Timeline section

    The maximum description length for the event is 300 chars
