+== API
+
+Some APM app features are provided via a REST API:
+
+* <<agent-config-api>>
+
+TIP: Kibana provides additional <<api,REST APIs>>,
+and general information on <<using-api,how to use APIs>>.

+=== Agent Configuration API
+
+The Agent configuration API allows you to fine-tune your APM agent configuration,
+without needing to redeploy your application.
+
+The following Agent configuration APIs are available:
+
+* <<apm-update-config>> to create or update an Agent configuration
+* <<apm-delete-config>> to delete an Agent configuration.
+* <<apm-list-config>> to list all Agent configurations.
+* <<apm-search-config>> to search for an Agent configuration.
