Spotify URIs are unique, static identifiers returned and consumed by several parts of our APIs in order to represent a particular Spotify content object, such as a track, an album, a playlist, a user etc.
On the 11th September 2018 we will roll out a change across all our APIs to simplify the URIs used to represent playlist objects. Instead of a long URI such as spotify:user:spotify:playlist:37i9dQZF1DZ06evO3OC4Te, you will now get the more succinct but still unique spotify:playlist:37i9dQZF1DZ06evO3OC4Te.
