HTTP API Notifications

A Notification is a HTTP request sent by the Ozeki Phone System in a HTTP POST request. You can set the phone system to send notifications to given URL addresses. You can also set some of the addresses in command parameters. You can set different URL addresses to different types of notifications. This way it can get an OzML (Ozeki XML) response from the previously set addresses. The OzML response, which is a http response, will then run on the Ozeki Phone System.

If you would like to find out where to set the target URL of a notification, check out this article.
