Notification Format

The Northbound Notifications are sent to a destination as HTTP or HTTPS POST requests. The message body is a JSON map that contains the notification data. The JSON map is in this format:

Key	Datatype	Operation
model_type	String	All
operation	String	All
pkid	String	All
hierarchy	String	All
new_data	Map	Create/Update
previous_data	Map	Update/Delete

The keys in the new_data and old_data maps are the attribute names for the given model type.

Example
