Spotify Apps still available? - spotify

Does Spotify sill supports in-app Apps? I saw a couple of them the other but cannot find any examples/docs today?
Did Spotify really stopped apps that run inside the Spotify App?

Please note: Future releases of the Spotify Desktop client will no
longer feature an App Finder tab and will no longer support the
presentation of Spotify Apps, therefore this API has been
discontinued.

Spotify Unity SDK

Does anyone know, do I need any kind of addition rights (or license agreements) for implementing custom Unity wrapper for Spotify SDK? On its own, the Spotify Unity wrapper will not include any Spotify libs (no Android nor iOS). Each developer will be prompted to download appropriate SDK from the official Spotify website and import into Unity project manually.
I am considering the possibility of selling the custom Unity wrapper for Spotify SDK on the market (Unity Asset Store etc.). I will NOT sell any Spotify resources/libs, just my custom implementation of Unity wrapper for Spotify. But anyway, I need the information about the possible required granted permissions from the Spotify itself.
If you have any kind of useful information according to this case, please, share with me. Thank you!
I can't give any specific legal advice, I'd suggest you approach a legal expert - but it's worth checking out Spotify's Developer Terms of Service, specifically noting the excerpt "Unless you receive Spotify’s written approval, you shall not use the Spotify Platform to incorporate Spotify Content into any game functionality".

Can the spotify (windows) desktop client be extended?

I found no clues in the developer documentation, but equalify claims that it integrates into the desktop application. They don't offer a free version so I couldn't try it out.
Is it possible/supported to create extensions for the desktop client and is there some hidden documentation available?
I'd be interested in developing one, but so far I had no luck in finding any documentation.
It used to be possible using the Spotify Apps API. I think you can still manually sideload apps, but there is no App Store or similar. Moreover, support for old Spotify Apps is about to be dropped completely in the future.
So no, there's no way to extend Spotify as far as I know.

Can I let the client stream the content from Spotify in a browser based player?

Couldn't find anything on Google about that topic, so I'm asking here.
I had an idea for a web based Spotify player (not like the offical one) and I would like to know if it's possible to let the client (user) stream the content from Spotify instead of my server (app). Would be pretty expensive if my server would have to stream the data and to send it to the client :-/
Thanks!
Unfortunately, there is no web library that you can use for streaming content from Spotify. The closest is the Spotify Play Button but that is a widget that remote controls Spotify from the desktop client or Spotify's web player.
You are limited to use the 30 seconds previews, or use the Android or iOS SDK if you were to build a mobile version of your site. The SDKs allow full playback for Spotify premium users.
There is a feature request for fetching full tracks on Spotify's Web API GitHub repo that you can watch or add comments to.

using Spotify's webAPI in an iOS app

So I'm in the process of developing an iOS app and I wanted to use the Spotify web API for searching and looking up songs in Spotify. However, I can't really tell if that is how to do it or if there would be better ways to do it and wanted to clarify before I began. Thanks in advance!
If you'd like the use the Web API, it works just the same as any other JSON REST API, so a lot of the tutorials out there for doing that on iOS will help you just fine. For converting between JSON and Objective-C data structures, newer iOS versions have NSJSONSerialization, otherwise I can recommend the open-source TouchJSON.
Also, you might want to look at CocoaLibSpotify, which is an Objective-C library for interacting with the Spotify service in a much more integrated way than the Web API — including music streaming. However, it does require a Spotify user be logged in to use.

Can't develop apps on latest Spotify build

I've been developing a Spotify app for a while but a new version came out that doesn't allow for app development (can't find the local app anymore).
I reverted back to the older build that used to be available on the Previews section of Spotify but every time I restart Spotify it re-installs the latest version.
Is there a way to either prevent the auto update or get a newer build that one can develop on?
The bundle loading logic changed with Spotify 0.8.3. Just search for the Spotify tag on Stack Overflow and you'll find many, many duplicates of your question.
This one has the answer you're looking for: Spotify apps dead after update?
