# API Endpoints

MokoWaaS provides 6 remote management endpoints accessible via query string parameter. All endpoints require HTTPS and Bearer token authentication.

## Authentication

All endpoints require the `health_api_token` as a Bearer token in the Authorization header:

```
Authorization: Bearer <health_api_token>
```

The token is auto-generated during plugin installation and stored as a read-only parameter in the plugin configuration. It can also be passed as a `token` query parameter as a fallback.

Token validation uses `hash_equals()` for timing-safe comparison. If no token is configured, the endpoint returns HTTP 503. An invalid token returns HTTP 401.

## Endpoints

## Error Responses

All endpoints return errors in a consistent format:

```json
{
  "error": "Error description",
  "message": "Additional detail (optional)"
}
```

### Common Error Codes

| HTTP Status | Meaning |
|---|---|
| 400 | Bad request (unknown action, missing parameters) |
| 401 | Invalid or missing authentication token |
| 405 | Wrong HTTP method (e.g. GET when POST is required) |
| 500 | Server error during operation |
| 503 | No API token configured |

## Unknown Actions

Requesting an unknown action returns HTTP 400 with the list of available actions:

```json
{
  "error": "Unknown action",
  "action": "invalid",
  "available": ["health", "install", "update", "cache", "backup", "info"]
}
```

## Joomla REST API Routes

In addition to the query-string endpoints above, MokoWaaS registers standard Joomla API routes via the `plg_webservices_mokowaas` plugin:

| Route | Controller |
|---|---|
| `GET /api/v1/mokowaas/health` | HealthController |
| `POST /api/v1/mokowaas/cache` | CacheController |
| `POST /api/v1/mokowaas/update` | UpdateController |

These routes use Joomla's standard API authentication (API token in `X-Joomla-Token` header) and are useful for integrations that already use the Joomla API framework.
