Message Echo

Message echo event is invoked whenever message is sent to user. This callback allows you to track all messages being sent no matter if they're sent by you or by someone else. For example messages sent to Facebook users directly from Facebook Page administration can be easily recorded. The same situation can happen when you reply the user from Amio integration (i.e. you reply from Zendesk).
