Spotify pulled the rug out from developers last week, announcing sudden changes to its API policies just before Thanksgiving that cut new apps and apps in development off from access to the platform’s data.
As of November 27th, the day Spotify revealed the changes, new “Web API use cases” will lose access to certain kinds of music data, according to the announcement. The data includes the ability to access Spotify’s catalog information about related artists and Spotify’s algorithmic and editorially-curated playlists. This change affects apps that are in development mode, meaning they’re under construction or used by up to 25 people, and new apps registered on or after the day of the announcement.
If you already have an app that’s widely available, it appears that your app can still access the affected endpoints as it could before. But for developers who have been working on an app or building one for more limited use, this is a major and disheartening change.
“Without warning and on a major holiday, Spotify cut access to a bunch of very useful API endpoints”
“Basically, without warning and on a major holiday, Spotify cut access to a bunch of very useful API endpoints that they’d been providing for years,” Faisal Alquaddoomi, who had been working on an app to visualize music on a DIY LED display, tells The Verge. Alquaddoomi wasn’t aware of the changes until seeing the blog post and says that Spotify didn’t send a proactive notification.
Douglas Adams, a software engineer (who is not the famous author), uses Spotify’s APIs to “measure the therapeutic impact of music on patients undergoing life saving treatments” as part of a project he’s working on with UCLA. He says the APIs are “critical” to the study and that he had to work through the holiday weekend to mitigate the impact of the changes on the project. “The alternative is not a straight-forward replacement and will take weeks of work to approach the capability I had before Spotify’s change,” Adams says.
Broken Holiday, a lo-fi producer, has been working on an app for artists to manage multiple playlists using automation. But with the API changes, the app can’t see what’s on a given playlist, Broken Holiday says.
Spotify has vaguely attributed the need for the API changes to improving security:
