  title: Argo CD API
  description: >-
    The Argo CD API provides REST endpoints for managing GitOps continuous
    delivery on Kubernetes. It enables creating and managing applications,
    projects, repositories, clusters, and certificates. The API supports
    syncing application state to match the desired state declared in Git,
    querying health and sync status, managing access control, and
    configuring notifications. All operations require authentication via
    bearer token obtained from the session endpoint.
