Starting January 1, 2026, developers based in the Republic of Korea must provide a server-to-server notification endpoint when registering a new Services ID or updating an existing Services ID to associate their website with an app signed in with Apple.
As a reminder, registering a notification endpoint allows Apple to send you important updates about the people using your app and their account status, including:
- Changes in email forwarding preferences.
- Delete account in your app.
- Permanently Delete Apple Account.
To learn more about server-to-server notifications, see WWDC20 Session 10173: Get the most out of signing in with Apple.
If you receive these notifications, you should immediately update all data related to the account change in the app, as well as any necessary server infrastructure, to give people more control over the personal data they have shared. For more information, see Process changes to sign in with Apple accounts.
Before submitting a new app to the App Store, or updating an existing app’s configuration to register a new Services ID or change an existing Services ID, please read the guidance below.
Account change guidance
Account changes are directly related to privacy and control for the user and their personal data, and confirming account changes should be simple and transparent.
For account email forwarding changes:
- Ensure that all displayed user data affected by the account change matches the change event in the notification payload. Usually this data is displayed in the account settings of the app or in the user profile.
- If people need to visit a website to change or verify their email address, include a link directly to the page on your website where they can complete the process.
- Keep users informed. If the change in email forwarding affects other services you provide, let them know. If your app supports in-app purchases, help people understand how billing, order tracking, and cancellations are handled with the new email address.
To delete account:
Note: Always follow applicable legal requirements for storing and maintaining user information and for handling account changes and deletions. This includes compliance with local laws where your apps are available. If you have any questions about your legal obligations, check with your legal advisor.
