  title: Envoy Admin Certificates Configuration API
  description: The Envoy Admin API provides local administrative access to a running Envoy proxy instance. It exposes endpoints for inspecting configuration, checking health, viewing statistics, managing log levels, and controlling the runtime state of the proxy. The Admin API is typically bound to a local interface (default port 9901) and is not intended for external exposure in production environments.
