API & Developer Experience

REST, WebSocket and Prometheus APIs with scoped tokens.

API & Developer Experience

Every UI action is backed by a programmable API. Build scripts, CI/CD pipelines and third-party tools around the REST endpoints, consume live cluster events over WebSockets or SSE, and expose metrics to Prometheus.

Scoped API tokens let you grant least-privilege access to automation, while the plugin SDK makes it easy to ship custom modules that look and feel like native ProxmoxVEx features.

Capabilities

Automate every operation through a REST and WebSocket API, scrape Prometheus metrics

  • ✓Full REST API covering clusters, VMs, storage, networking and more
  • ✓WebSocket and Server-Sent Events for live updates
  • ✓Prometheus-compatible /api/metrics endpoint
  • ✓Scoped API tokens with bearer authentication
  • ✓Plugin SDK with UI, i18n and settings support
