ServiceNow Events and Notifications

Version Yokohama

ServiceNow supports outbound event-driven integrations through business rules, event management, and outbound REST messages. When records are created, updated, or deleted in ServiceNow tables, business rules can trigger outbound HTTP POST notifications to external webhook receivers. This specification documents the event payloads and notification patterns used by ServiceNow's outbound integration capabilities for incident, change, and problem management workflows.
