API Reference

Overview

Muximux provides a REST API for managing configuration, apps, groups, health, authentication, icons, and themes. All endpoints return JSON.

When authentication is enabled, most endpoints require a valid session cookie or API key (X-Api-Key header). Write operations (POST, PUT, DELETE) require the admin role.

Authentication

Endpoint	Method	Auth Required	Description
/api/auth/login	POST	No	Login with username/password
/api/auth/logout	POST	No	Logout (clears session)
/api/auth/status	GET	No	Check auth status and current user
/api/auth/me	GET	Yes	Get current user details
/api/auth/password	POST	Yes	Change password (builtin auth only)
/api/auth/oidc/login	GET	No	Redirect to OIDC provider
/api/auth/oidc/callback	GET	No	OIDC callback handler

Login request:

POST /api/auth/login
{
  "username": "admin",
  "password": "secretpassword"
}

Login response:

{
  "success": true,
  "user": {
    "username": "admin",
    "role": "admin",
    "email": "admin@example.com",
    "display_name": "Admin User"
  }
}

API key authentication:

Instead of a session cookie, you can authenticate with an API key by including the X-Api-Key header:

GET /api/apps
X-Api-Key: your-api-key-here

The API key is configured in auth.api_key in your config file.

Configuration

Endpoint	Method	Role	Description
/api/config	GET	Any	Get full configuration
/api/config	PUT	Admin	Update full configuration

The PUT endpoint accepts the full configuration object. Changes to most settings take effect immediately. Server-level settings (listen address, TLS, gateway) and auth method changes require a restart.

WebSocket

Endpoint	Protocol	Description
/ws	WebSocket	Real-time event stream

Connect to /ws to receive real-time updates. Events are sent as JSON messages:

{"type": "config_updated", "data": {...}}
{"type": "health_changed", "data": [...]}
{"type": "app_health_changed", "data": {"name": "Sonarr", "status": "healthy", ...}}

Event types:

Type	Description
config_updated	Configuration was changed (via Settings panel or API)
health_changed	Health status changed for one or more apps
app_health_changed	Health status changed for a specific app

The WebSocket client automatically reconnects if the connection drops, using exponential backoff up to 10 retry attempts.

---

Rate Limiting

The login endpoint (POST /api/auth/login) is rate-limited to 5 attempts per IP address per minute to prevent brute-force attacks. If the limit is exceeded, the endpoint returns HTTP 429 (Too Many Requests).

Other API endpoints are not rate-limited.
