Spotify is a streaming music service for multiple platforms. This tag covers Spotify's various developer libraries and public APIs, including Web API, mobile SDKs, and Web Playback SDK.
The Spotify Platform allows developers to integrate Spotify in their applications using Spotify's Web API, iOS SDK, Android SDK, and Web Playback SDK. Read more about these and other tools on the Spotify for Developers website.
What Questions should I ask?
Questions using this tag should be about how to use one of these platforms. You may find that in some cases, a question that arises whilst developing for these platforms is not Spotify specific; e.g. a common JavaScript question whilst creating a Spotify Web API Application, or an Android question whilst using the Android SDK. In these cases, you should tag your question with the javascript or 
android tag instead.
Platforms
Web API
The Web API provides developers with an interface to query Spotify's extensive music catalogue through a REST interface, using OAuth 2.0 for authentication.
Useful Resources
Web Playback SDK
The Spotify Web Playback SDK makes it possible to add audio streaming to your website. You can use it in conjunction with the Spotify Web API to build rich applications on top of the Spotify platform.
Useful Resources
iOS SDK
The Spotify iOS SDK makes it easy to add audio streaming, playlist manipulation, metadata lookup and other Spotify features to iOS apps.
Useful Resources
Android SDK
Similarly to the iOS SDK, the Spotify Android SDK enables developers to do things like music playback, playlist manipulation, and metadata lookup.
