📤 Tasks

  • 스토어 심사 기준을 만족시키기 위해 회원 탈퇴 과정에서의 OAuth revoke를 추가하였습니다.
  • OAuth 인증과 달리 revoke는 표준화가 되어있지 않아서 단순 외부 요청으로 구현하였습니다.

💌 To Reviewer

  • Special thanks to 테스트 도와준 상엽쌤 @sangyup12
  • 기존 인증과정과 동일한 형태로 환경변수를 Property객체로 관리하도록 구현하였습니다.
  • 애플의 경우 revoke 과정에서 애플에게 토큰 발급을 요청하고, 해당 토큰으로 client_secret을 jwt로 생성합니다.
  • 실제 revoke요청 흐름이 존재하는 adapter에서 client_secret을 jwt로 생성하는 로직을 분리하고 의존성 주입을 적용하였습니다.

Summary by CodeRabbit

  • 새로운 기능

    • 회원 탈퇴 시 Apple 소셜 로그인 연동 해제를 지원합니다.
    • 탈퇴 요청에 Apple authorization_code를 전달할 수 있습니다.
    • Apple OAuth 토큰 폐기 및 관련 오류 처리가 추가되었습니다.
  • 문서

    • 회원 탈퇴 API 문서에 소셜 로그인 연동 해제 조건과 처리 결과를 반영했습니다.
  • 버그 수정

    • OAuth 연동 해제에 실패해도 회원 탈퇴와 후속 이벤트 처리는 계속 진행됩니다.

Apple 회원은 삭제 전에 authorizationCode를 검증하십시오. WithdrawRequestauthorizationCode를 검증하지 않고 WithdrawCommand로 전달합니다. MemberService.withdraw는 회원 삭제를 완료한 뒤 AppleOAuthRevokeAdapter를 호출합니다. 코드가 없거나 비어 있으면 revoke 요청이 실패할 수 있으며, 해당 BaseException은 로그만 남기고 무시됩니다. Apple 연동 해제가 누락된 상태로 회원 삭제가 완료될 수 있습니다. Apple 회원에게만 삭제 전에 authorizationCodenull 및 공백 여부를 검증하십시오. Google 회원에는 이 검증을 적용하지 마십시오.

🌐 Web query:

site:developer.apple.com Sign in with Apple authorization code can only be used once revoke refresh token

💡 Result:

<search_synthesis>
The Sign in with Apple authorization code is a single-use string that is valid for five minutes [1][2]. Once this code is exchanged for tokens (identity token, access token, and refresh token) via the Apple authentication server, it cannot be reused [3][4][5]. To revoke a refresh token, you must use the Apple token revocation endpoint (/auth/revoke) [6][7]. This process requires sending a POST request containing your client_id, client_secret, and the token you wish to invalidate (the refresh token or access token) [6][8]. Key points regarding these processes: - Authorization Code: It must be exchanged immediately after receipt. Once used, it is invalidated by Apple&#39;s servers [1][4]. - Refresh Token Revocation: The revocation endpoint is the programmatic way to invalidate a user&#39;s session [7][9]. Once the refresh token is revoked, it can no longer be used to obtain new access tokens [6][7]. - Missing Tokens: If you do not have a valid refresh or access token (for example, if a user has deleted their account and you no longer have their tokens), you cannot use the revocation endpoint. In such cases, you must proceed with your own account deletion procedures according to Apple&#39;s guidelines [7][9].

Request an authorization to the Sign in with Apple server | Apple Developer Documentation Skip Navigation - Sign in with Apple REST API - Request an authorization to the Sign in with Apple server Web Service Endpoint # Request an authorization to the Sign in with Apple server Add a Sign in with Apple authorization flow to apps and web services that can’t directly access Sign in with Apple JS. ## URL ``` GET https://appleid.apple.com/auth/authorize ``` ## Query Parameters `client_id` `string` (Required) The identifier (App ID or Services ID) for your app. The identifier must not include your Team ID, to help prevent the possibility of exposing sensitive data to the end user. `nonce` `string` A unique, single-use string that your app provides to associate a client session with the user’s identity token. This value is also used to prevent replay attacks, and allows you to correlate the initial authentication request with the identity token provided in the authorization response. `redirect_uri` `string` (Required) The destination URI associated to your app, to which the authorization redirects. The URI must use the HTTPS protocool, include a domain name, can’t be an IP address or localhost, and must not contain a fragment identifer (#). For more information, see Configuring your environment for Sign in with Apple. `response_mode` `string` The type of response mode expected. Valid values are`query`,`fragment`, and`form_post`. If you requested any scopes, the value must be`form_post`. `response_type` `string` (Required) The type of response requested. Valid values are`code` and`id_token`. You can request only`code`, or both`code` and`id_token`. Requesting only`id_token` is unsupported. When requesting`id_token`,`response_mode` must be either`fragment` or`form_post`. `scope` `string` The amount of user information requested from Apple. Valid values are`name` and`email`. You can request one, both, or none. Use space separation and percent-encoding for multiple scopes; for example,`"scope=name%20email"`. `state` `string` An arbitrary string that your app provides, representing the current state of the authorization request. This value is also used to mitigate cross-site request forgery attacks, by comparing against the state value contained in the authorization response. ## Response Codes ` 200 OK` `OK` Request succeeded. Content-Type: application/json ` 404 Not Found` `Not Found` Resource not found. Content-Type: application/json ## Mentioned in Receiving a User’s Identity Token ## Discussion Use this endpoint to request authorization for your app to receive the user’s information with Sign in with Apple. If your app is contained within an app group, the user credentials are associated with the primary app and shared across the group. To learn more about app groups, visit Configuring your environment for Sign in with Apple. ### Get the user information and tokens When the Sign in with Apple UI appears in the opened browser tab, the user can sign in and accept any terms and conditions for your app. After Apple processes the authorization request, the handling of the response depends on the value in`response_mode`: For the`query` value, the response parameters are added to the`redirect_uri` value as query parameters, and the browser is redirected to the resulting value. For the`fragment` value, the response parameters are added to the`redirect_uri` value as a fragment, and the browser is redirected. For the`form_post` value, an HTTP POST request containing the results of the authorization is sent to the`redirectURI`. The HTTP body contains the result parameters with`application/x-www-form-urlencoded` content type. A successful response contains the following parameters: `code` A single-use authorization grant code that’s valid for five minutes. To learn how to validate this code to obtain user tokens, see Token validation. `id_token` A JSON web token (JWT) containing the user’s identity information.

Configure an authorization object and add a button that allows users to sign in to your webpage with their Apple Account. ### Embed Sign in with Apple JS Include the script tag and link to Apple’s hosted version of the Sign in with Apple JS framework in your web page: ``` <script type="text/javascript" src="https://appleid.cdn-apple.com/appleauth/static/jsapi/appleid/1/en_US/appleid.auth.js"></script> ``` Embedding the framework gives you access to the Sign in with Apple authorization features. ### Configure the Authorization Object To get started quickly, configure Sign in with Apple JS with a default markup setup. Alternatively, use JavaScript to configure the authorization object, or use a combination of the two. Configure the authorization object using only markup by setting the meta tags in the header section and displaying a Sign in with Apple button. For more information about the client configuration, see ClientConfigI. ``` <html> <head> <meta name="appleid-signin-client-id" content="[CLIENT_ID]"> <meta name="appleid-signin-scope" content="[SCOPES]"> <meta name="appleid-signin-redirect-uri" content="[REDIRECT_URI]"> <meta name="appleid-signin-state" content="[STATE]"> <meta name="appleid-signin-nonce" content="[NONCE]"> <meta name="appleid-signin-use-popup" content="true"> </head> <body> <div id="appleid-signin" data-color="black" data-border="true" data-type="sign in"></div> <script type="text/javascript" src="https://appleid.cdn-apple.com/appleauth/static/jsapi/appleid/1/en_US/appleid.auth.js"></script> </body> </html> ``` You can also configure the authorization object using the JavaScript APIs and display a Sign in with Apple button. ``` <html> <head> </head> <body> <script type="text/javascript" src="https://appleid.cdn-apple.com/appleauth/static/jsapi/appleid/1/en_US/appleid.auth.js"></script> <div id="appleid-signin" data-color="black" data-border="true" data-type="sign in"></div> <script type="text/javascript"> AppleID.auth.init({ clientId : &`#39`;[CLIENT_ID]&`#39`;, scope : &`#39`;[SCOPES]&`#39`;, redirectURI : &`#39`;[REDIRECT_URI]&`#39`;, state : &`#39`;[STATE]&`#39`;, nonce : &`#39`;[NONCE]&`#39`;, usePopup : true }); </script> </body> </html> ``` Additionally, you can combine the two configuration options: you can set the meta tags in the header, while at the same time using JavaScript APIs. This configuration provides a default implementation through the meta tags, but gives you the ability to override the initial information using the JavaScript APIs. ### Handle the Authorization Response After the user clicks the Sign in with Apple button, the framework sends the authorization information to Apple. Apple processes the authorization request, and sends an HTTP POST request containing the results of the authorization to the URL provided in redirectURI. The HTTP body contains the result parameters with a content-type of`application/x-www-form-urlencoded`. A successful response contains the following parameters: `code` A single-use authentication code that expires after five minutes. To learn how to validate this code to obtain user tokens, see Token validation. `id_token` A JS…[truncated] <title>Token validation | Apple Developer Documentation</title> https://developer.apple.com/documentation/signinwithapplerestapi/generate-and-validate-tokens # Token validation Validate an authorization grant code delivered to your app to obtain tokens, or validate an existing refresh token. ## Discussion The validation server returns a `TokenResponse` object in the response body of a successful validation request. Use this endpoint to either authorize a user by validating the authorization code received by your app, or by validating an existing refresh token to verify a user session or obtain access tokens. ### Validate the authorization grant code When you send an authorization request to the validation server, include the following form data parameters: - `client_id` - `client_secret` - `code` - `grant_type` - `redirect_uri` > Note: > When authorizing a user with your app, include the `redirect_uri` parameter only if the application provided a `redirect_uri` in the initial authorization request. The following is an example authorization validation request URL via `cURL`: ```console curl -v POST "https://appleid.apple.com/auth/token" \ -H &`#39`;content-type: application/x-www-form-urlencoded&`#39`; \ -d &`#39`;client_id=CLIENT_ID&`#39`; \ -d &`#39`;client_secret=CLIENT_SECRET&`#39`; \ -d &`#39`;code=CODE&`#39`; \ -d &`#39`;grant_type=authorization_code&`#39`; \ -d &`#39`;redirect_uri=REDIRECT_URI&`#39`; ``` After the server validates the authorization code, the endpoint returns the identity token, an access token, and a refresh token. The following is an example authorization validation response: ```json { "access_token": "adg61...67Or9", "token_type": "Bearer", "expires_in": 3600, "refresh_token": "rca7...lABoQ", "id_token": "eyJra...96sZg" } ``` Use the refresh token to verify the user session from the server and obtain access tokens. ### Validate an existing refresh token When performing a validation request, you must include the following form data parameters: - `client_id` - `client_secret` - `grant_type` - `refresh_token` The following is an example validation request URL using `cURL`: ```console curl -v POST "https://appleid.apple.com/auth/token" \ -H &`#39`;content-type: application/x-www-form-urlencoded&`#39`; \ -d &`#39`;client_id=CLIENT_ID&`#39`; \ -d &`#39`;client_secret=CLIENT_SECRET&`#39`; \ -d &`#39`;grant_type=refresh_token&`#39`; \ -d &`#39`;refresh_token=REFRESH_TOKEN&`#39`; ``` After the server validates the refresh token, the endpoint returns the identity token and an access token. The following is an example refresh token validation response: ```json { "access_token": "beg510...67Or9", "token_type": "Bearer", "expires_in": 3600, "id_token": "eyJra...96sZg" } ``` --- Copyright © 2026 Apple Inc.

A simple confirmation to continue appears even if the app bundle IDs are different across systems, such as iOS, macOS, and the web. ### Authenticate the user and request information Initialize an authentication session with your app server and associate a client session with an ID token using the `nonce` value. You can request to receive the user’s information, such as name and email address. If the user approves accessing this information, your authorization request includes the requested information. Sign in with Apple protects user accounts by using two-factor authentication. Users that log in to an Apple device can quickly sign in to your app in the following ways: - With Face ID or Touch ID on passcode-protected devices - With a passcode, if Touch ID or Face ID isn’t available - With an Apple Account password, if the passcode isn’t set Native apps only allow the signed-in iCloud user to use Sign in with Apple. Web-based interactions allow logins using any Apple Account. > Note: > On non-Apple devices, users must log in with their Apple Account, password, and two-factor authentication code. Apple determines whether a user is a real person by combining on-device machine learning, account history, and hardware attestation using privacy-preserving mechanisms. There are three possible values when determining whether a user is a real person: - `2` (or `LikelyReal`): The user appears to be a real person, and you can treat this account as a valid user. You can skip any additional fraud verification checks or CAPTCHAs that your app normally uses. For more information, see doc://com.apple.documentation/documentation/AuthenticationServices/ASUserDetectionStatus/likelyReal. - `1` (or `Unknown`): The system can’t determine whether the user is a real person. The server may return this value if status determination takes too long. Treat this user as any other account with limited information that requires additional verification steps. Don’t block service, because the user may be a real person. For more information, see doc://com.apple.documentation/documentation/AuthenticationServices/ASUserDetectionStatus/unknown. - `0` (or `Unsupported`): Real user status is only available in iOS 14 and later, macOS 11 and later, watchOS 7 and later, and tvOS 14 and later. Previous versions of iOS, macOS, watchOS, tvOS return `Unsupported`. For more information, see doc://com.apple.documentation/documentation/AuthenticationServices/ASUserDetectionStatus/unsupported. This system for detecting whether the user is real is tuned for high-precision and moderate recall time. You may also use it as a feature in your own machine-learning models for detecting account fraud. When someone uses your app and Sign in with Apple for the first time, the identification servers return the user status. Subsequent attempts don’t return the user status. After the user logs in to your app using Sign in with Apple on one of their devices, they can sign in on all of their devices. Deleting your app from a device doesn’t affect this capability. If the user reinstalls your app, they can continue to use Sign in with Apple on any of their devices to sign in with their existing account. ### Send information to app servers and verify tokens After successfully authenticating the user, the server returns an identity JSON Web Token…[truncated] <title>Receiving a User’s Identity Token | Apple Developer Documentation</title> https://developer.apple.com/documentation/signinwithapple/receiving-a-users-identity-token Receiving a User’s Identity Token | Apple Developer Documentation # Receiving a User’s Identity Token Retrieve the user’s information from Apple Account servers ## Overview After successfully authenticating the user, the server returns an identity JSON Web Token (JWT), single-use authorization grant code, the state contained in the authorization request, and user identifier to your app. For more information, see `Request an authorization to the Sign in with Apple server` and id _token . The information you retrieve must include the credentials required to verify the user’s identity. The server returns the credentials and user information based on the initial request. The information that returns can include user identity, full name, verified email address, and real user status. Note If the user signs in with a managed Apple Account, the value of the `email` claim is a real email address, not a proxy address. Alternatively, if the managed Apple Account is in Apple School Manager, the `email` claim may be empty. Students, for example, often don’t have an email that the school issues. Use the authorization grant code to verify the token claims with Apple servers, and exchange them for refresh tokens. For more information, see `Token validation`. Use the user identifier instead of an email address to identify the user. The user identifier remains unique and static for your developer team. If you request the user’s verified email address, Sign in with Apple prompts the user to share it with your app. The user may choose to share their real email address or an anonymous one that uses the private email relay service. In both cases, Apple verifies that the email address works and is ready for use. If you request the user’s full name, Sign in with Apple collects the information to pass along to your app. The name defaults to the user’s name from their Apple Account, but the user can change their name when creating an account. Important Apple doesn’t receive the user’s full name shared with the system UI. The raw data is passed directly to your app from the browser and is not included in the user’s identity token. To help prevent cross-site scripting attacks, validate and sanitize the user-submitted first and last name values before storing on your app servers. For more information, see Communicating using the private email relay service. Add a Sign in with Apple authorization flow to apps and web services that can’t directly access Sign in with Apple JS.

실패한 Apple revoke 요청을 내구성 있게 재시도하십시오.

AppleOAuthRevokeAdapter.revokeauthorizationCoderefreshToken으로 교환한 뒤, 해당 refreshToken을 저장하지 않고 같은 호출에서 revoke 요청을 보냅니다. revoke 요청이 실패하면 MemberService.revokeOAuthConnection이 예외를 로그만 남기고 종료하므로, 획득한 refreshToken과 예외가 모두 사라집니다. Apple authorization code는 일회성 코드이므로 같은 코드로 복구할 수 없습니다.

획득한 refreshToken과 재시도 상태를 저장하고, 저장된 refreshToken을 사용하는 재시도 또는 보상 작업을 실행하십시오. 영구 실패는 운영자가 확인할 수 있도록 남겨야 합니다.
