| GET       | [/api/config](#config)                           | Get configuration information        |



### Config

**Endpoint**

```
GET /api/config
```

**Response**

| Key             | Type     | Value                                     |
| --------------- | -------- | ----------------------------------------- |
| version         | string   | forked-daapd server version               |
| websocket_port  | integer  | Port number for the [websocket](#push-notifications) (or `0` if websocket is disabled) |
| buildoptions    | array    | Array of strings indicating which features are supported by the forked-daapd server |


**Example**

```
curl -X GET "http://localhost:3689/api/config"
```

```
{
  "websocket_port": 3688,
  "version": "25.0",
  "buildoptions": [
    "ffmpeg",
    "iTunes XML",
    "Spotify",
    "LastFM",
    "MPD",
    "Device verification",
    "Websockets",
    "ALSA"
  ]
}
```

## Push notifications

If forked-daapd was built with websocket support, forked-daapd exposes a websocket at `localhost:3688` to inform clients of changes (e. g. player state or library updates).
The port depends on the forked-daapd configuration and can be read using the [`/api/config`](#config) endpoint.

After connecting to the websocket, the client should send a message containing the event types it is interested in. After that forked-daapd
will send a message each time one of the events occurred.

**Message**

| Key             | Type     | Value                                     |
| --------------- | -------- | ----------------------------------------- |
| notify          | array    | Array of event types                      |

**Event types**

| Type            | Description                               |
| --------------- | ----------------------------------------- |
| update          | Library update started or finished        |
| outputs         | An output was enabled or disabled         |
| player          | Player state changes                      |
| options         | Playback option changes (shuffle, repeat, consume mode) |
| volume          | Volume changes                            |
| queue           | Queue changes                             |
