  title: AppDynamics Alert and Respond Actions Applications API
  description: The AppDynamics Alert and Respond API enables programmatic management of health rules, policies, and actions within the AppDynamics Controller. Developers can create, update, and delete health rules that define performance thresholds, configure alerting policies that determine how violations are handled, and set up automated response actions. This API is essential for automating incident response workflows and integrating AppDynamics alerting with external notification and ticketing systems.
