Canvas Platform Notification Service

Platform Notification Service (PNS) enables server-to-server communication by allowing Canvas to send Notices (webhook deliveries) to LTI tools outside the scope of an active user session. Tools register notice handlers for specific event types and receive signed deliveries that integrate with the IMS LTI 1.3 security model.
