Starting January 1, 2026, developers in South Korea must provide a server-to-server notification endpoint when using Sign in with Apple. This endpoint enables Apple to send critical updates about user account changes, including email forwarding preference modifications, app-specific account deletions, and permanent Apple Account deletions.

The requirement aims to give users better control over their personal data while ensuring apps comply with privacy standards and local regulations.
