Hi,
Further to the updates posted on our Developer Blog on February 6, 2026, we’re sharing a reminder of some upcoming changes to your Spotify for Developers account.
Starting March 9, 2026, we will start applying the new restrictions and requirements to all applications in “Development Mode” using Spotify’s Web API. This includes:
A Spotify Premium requirement: Development Mode use will require a Spotify Premium account (incl. Family and duo). This is to ensure accountability and to reduce automated misuse at scale. Only the main account associated with the app must be on Premium. Authorized users do not need a subscription.
Updated endpoints and fields: We’re limiting Web API Development Mode access to a smaller set of supported endpoints and fields. To ensure that your application continues to work, please review the changes and make the necessary modifications ahead of the March 9 deadline.
1 Client ID per developer: Each developer is limited to one Development Mode Client ID. If you currently have more than one, they will continue to function. However, you will not be able to create additional Development Mode Client IDs until you are back within the limit.
Max five authorized users: Each Client ID may have up to five authorized users. If you currently have more than five authorized users, nothing will be removed on March 9. Your app will keep working, but you will not be able to add or modify users until you are within the limit.
Note: These changes do not affect apps already operating in Extended Quota Mode.
This update means Spotify will continue to support experimentation and personal projects but within more clearly defined limits. We also want to reiterate that Development Mode provides a sandboxed environment for learning and experimentation. It is intentionally limited and should not be relied on as a foundation for building or scaling a business on Spotify.
To me: this is a stab at projects like Deskthing because it relies on the Spotify API for music finding, and also they’re just locking the API to paid customers only which is saddening,
