An Account Event Handler is a way of allowing our system to notify your applications of activity on your account, for example the arrival of new messages in your Inbox or notification that a message has been delivered. It is a publicly accessible web page or web service that you develop and host for our system to post information to.
It is very important that your service handles each notification in at least a basic way. Even if you only want your application to react to inbound messages, your Account Event Handler will still be called for the other notification types.
A common error is assuming that your Account Event Handler will only be called when a message is received. This is not the case. If you do not check the notification type your Account Event Handler will end up processing message events and errors as if they were inbound message notifications.
