I'm trying to get the list of tracks from a Spotify playlist. But I need the updates of the playlist in real time. If any track gets added (or removed) in the playlist, I need a notification from Spotify API that the playlist is updated.
I first tried to accomplish my goal by getting the playlist data from Spotify API every 10 minutes and compare it to its previous version. But it's so inefficient.
I'm building the application with Flutter using spotify 0.8.0 package. But I'm okay with REST APIs.
Is there any other way for getting live update of a playlist?

So I'm Working on a NodeJs project and am wondering if there is a way to get audio from Spotify Like you Input a song URL and It plays the track, I've looked all around and can only find stuff for the web browser, I don't know if they even have a way. If there is any info about this please let me know.
You'd have to make calls through the Spotify API.
You can read more about the API here: Spotify API Documentation
This is a node.js specific library that you may also want to check out:

The answer provisioned and marked as correct is wrong.
The only way you can extract audio is by using a Windows VM, connect via RDP. Run a script to play Spotify programatically and record the audio.
Since this is the only solution. It is not possible to query data from Spotify.
Currently, I am able to play only the Preview version of the song using the song's preview_url from the response object. Is there any way to fetch the entire song?
Playback of full tracks is not supported in the Web API.
If you are making a mobile app, playback is offered through the mobile SDKs, but there is no full playback for web at this time.
Mobile SDKs can be found here:

I'd like to allow Spotify users to post a small note along with a song when they post in a collaborative playlist. Is this possible with a Spotify app, or will I have to implement something else? Thoughts?
+1 for the feature idea, but I don't believe it's possible with the current system. You could maintain your own database of comments linked to the playlist and track ids and display it in a Spotify app.
I have developed an iOS App which plays music from the users music library simultaneously with audio files which are included in the app. I have hired a developer to make several changes in the app, one of which enables the user to use their "Spotify" playlists instead of their "Music" playlists, if they have a spotify account. He tells me it is impossible for this functionality to work with the Spotify API.
Can someone please help me as I really need this functionality to work??
Thankyou.
This isn't possible with the Web API, however, take a look at CocoaLibSpotify which is a Mac and iOS library that allows you to access a user's Spotify playlists and play tracks.
I'm using the Spotify API 11.1.60 for iOS and created successfully an app that can download / play songs from Spotify, download and show the covers, execute searches. But I can't find a way to crossfade songs. I only can play one song a time.
Does anybody know how to crossfade songs?
I did not implement crossfade but I think the only solution is to bufferize your current song to be able to crossfade.
You have to update your music_delivery callback and your code used to play the sound. The solution depend on the sound engine your using (OpenAL, CoreAudio, ...)
