Getting started

This API provides some access to the local running Spotify-Client (Windows only).
You can fetch details for the current track, play/pause, skip/previous track and get notified on various events.

NOTE: This API is unofficial, things may brake in the future and there is no guarantee everything works out of the box.

First steps

Imports
So after you added the API to your project, you may want to add following imports to your files:

using SpotifyAPI.Local; //Base Namespace
using SpotifyAPI.Local.Enums; //Enums
using SpotifyAPI.Local.Models; //Models for the JSON-responses

Basic-Usage
Now you can actually start fetching infos from your spotify client, just create a new Instance of SpotifyLocalAPI:

private static SpotifyLocalAPI _spotify;

public static void Main(String[] args)
{
    _spotify = new SpotifyLocalAPI();
    if (!SpotifyLocalAPI.IsSpotifyRunning())
      return; //Make sure the spotify client is running
    if (!SpotifyLocalAPI.IsSpotifyWebHelperRunning())
      return; //Make sure the WebHelper is running

    if(!_spotify.Connect())
      return; //We need to call Connect before fetching infos, this will handle Auth stuff

    StatusResponse status = _spotify.GetStatus(); //status contains infos
}

Configuration

Different spotify versions often require different configuration. Some versions run their web-helper on port 4371, others on 4381. Also, some use https, and others use http. You can use SpotifyLocalAPIConfig to configure the API:

_spotify = new SpotifyLocalAPI(new SpotifyLocalAPIConfig
{
    Port = 4371,
    HostUrl = "https://127.0.0.1"
});

Anti-Virus Blocking Response

Some Anti-Virus Software blocks the response from spotify due wrong headers. Currently, it's confirmed for AVG's LinkScanner and Bitdefender. Adding http://SpotifyAPI.spotilocal.com:4380 to the URL-Exceptions seems to fix it for most users. More infos can be found here

Client Status

Calling _spotify.GetStatus() after connecting returns the following StatusResponse:

public int Version { get; set; }

public string ClientVersion { get; set; }

public bool Playing { get; set; }

public bool Shuffle { get; set; }

public bool Repeat { get; set; }

public bool PlayEnabled { get; set; }

public bool PrevEnabled { get; set; }

public bool NextEnabled { get; set; }

public Track Track { get; set; }

public double PlayingPosition { get; set; }

public int ServerTime { get; set; }

public double Volume { get; set; }

public bool Online { get; set; }

public bool Running { get; set; }

Most of the properties are self-explanatory, some notes:

• Shuffle and Repeat currently always return false

Current Track

The current Track can be fetched via _spotify.GetStatus().Track and contains following properties/methods:

• TrackResource - SpotifyResource which contains Track Name and Uri
• AlbumResource - SpotifyResource which contains Album Name and Uri
• ArtistResource - SpotifyResource which contains Artist Name and Uri (Only the main artist will be listed)
• IsAd() will check whether the current track is an AD
• Various methods for getting the album art:
  • string GetAlbumArtUrl(AlbumArtSize size)
  • Task<Bitmap> GetAlbumArtAsync(AlbumArtSize size)
  • Bitmap GetAlbumArt(AlbumArtSize size)
  • Task<byte[]> GetAlbumArtAsByteArrayAsync(AlbumArtSize size)
  • byte[] GetAlbumArtAsByteArray(AlbumArtSize size)

Events

To receive events, make sure you listen for them _spotify.ListenForEvents = true;
You can set a SynchronizingObject, then the events will be called on the specific context

Following events can be overriden:

• OnPlayStateChange - triggers when the player changes from play to pause and vice versa
• OnTrackChange - triggers when a new track will be played
• OnTrackTimeChange - triggers when a track is playing and track-time changes
• OnVolumeChange - triggeres when the internal volume of spotify changes

Methods

Furthermore, following methods are available:

• void Mute() - will mute the Spotify client via WindowsAPI
• void UnMute() - will unmute the Spotify client via WindowsAPI
• bool IsSpotifyMuted() - will return wether the Spotify client is muted
• void SetSpotifyVolume(float volume = 100) - sets the windows volume of spotify (0 - 100)
• float GetSpotifyVolume() - returns the windows volume of spotify (0 - 100)
• void Pause() - will pause spotify's playback
• void Play() - will resume spotify's playback
• void PlayURL(string uri, string context = "") - will play a spotify URI (track/album/playlist) in the specifc context (can be a album/playlist URI)
• void Skip() - will skip the track via an emulated media key
• void Previous() - will play the previous track via an emulated media key
• bool IsSpotifyRunning() - returns true if a spotify client instance is running, false if not
• bool IsSpotifyWebHelperRunning() - returns true if a spotify web-helper instance is running, false if not
• void RunSpotify() - will attempt to start a Spotify instance
• void RunSpotifyWebHelper() - will attempt to start a Spotify web-helper instance
