Hi, Before I begin my investigation, I want to explain our code-level support process for issues related to Sign in with Apple—as the issue you’re reporting may be the result of any of the following: An error in your app or web service request. A configuration issue in your Developer Account. An internal issue in the operation system or Apple ID servers. To ensure the issue is not caused by an error within your app or web service request, please review TN3107: Resolving Sign in with Apple response errors to learn more about common error causes and potential solutions when performing requests. If the technote does not help identify the cause of the error, I need more information about your app or web services to get started. To prevent sending sensitive JSON Web Tokens (JWTs) in plain text, you should create a report in Feedback Assistant to share the details requested below. Additionally, if I determine the error is caused by an internal issue in the operating system or Apple ID servers, the appropriate engineering teams have access to the same information and can communicate with you directly for more information, if needed. Please follow the instructions below to submit your feedback. Gathering required information for troubleshooting Sign in with Apple authorization and token requests For issues occurring with your native app, perform the following steps: Install the Accounts/AuthKit profile on your iOS, macOS, tvOS, watchOS, or visionOS device. Reproduce the issue and make a note of the timestamp when the issue occurred, while optionally capturing screenshots or video. Gather a sysdiagnose on the same iOS, macOS, tvOS, watchOS, or visionOS device. Create a report in Feedback Assistant, and ensure your feedback contains the following information: the primary App ID or Bundle ID the user’s Apple ID, email address, and/or identity token the sysdiagnose gathered after reproducing the issue the timestamp of when the issue was reproduced screenshots or videos of errors and unexpected behaviors (optional) For issues occurring with your web service, ensure your feedback contains the following information: the primary App ID and Services ID the user’s Apple ID, email address, and/or identity token the failing request, including all parameter values, and error responses (if applicable) the timestamp of when the issue was reproduced (optional) screenshots or videos of errors and unexpected behaviors (optional) Important: If providing a web service request, please ensure the client secret (JWT) has an extended expiration time (exp) of at least ten (10) business days, so I have enough time to diagnose the issue. Additionally, if your request requires access token or refresh tokens, please provide refresh tokens as they do not have a time-based expiration time; most access tokens have a maximum lifetime of one (1) hour, and will expire before I have a chance to look at the issue. Submitting your feedback Before you submit to Feedback Assistant, please confirm the requested information above (for your native app or web service) is included in your feedback. Failure to provide the requested information will only delay my investigation into the reported issue within your Sign in with Apple client. After your submission to Feedback Assistant is complete, please respond in your existing Developer Forums post with the Feedback ID. Once received, I can begin my investigation and determine if this issue is caused by an error within your client, a configuration issue within your developer account, or an underlying system bug.

Would really appreciate support with this invalid_client issue: I have a web app and have aligned the JWT Header and Payload JWT Header { "alg": "ES256", "kid": "ABC123DEFG" } JWT Payload { "iss": "DEF123GHIJ", "iat": 1234567890, "exp": 1234567890, "aud": "https://appleid.apple.com", "sub": "com.yourapp.service" The domains and callback are aligned and correct I've even created a new p8 and updated the Key_ID Sending Credentials to Apple (Token Request) Content-Type: application/x-www-form-urlencoded However, still no luck. Can anyone assist with identifying the possible error? Many thanks

I've been using Sign In with Apple for Web for the last six months, and it works well enough. Now, I'm updating the domain of the main application (we got the .com! yeah!) However, I can't find a way in the configuration UI to update the allowed redirect URLs for the application. I go to Identifiers -> My App -> Capabilities -> Sign In with Apple -> Edit button. It just allows me to edit whether this is a primary ID, or grouped ID, plus a callback URL (which I'm not currently using.)

Hello Developers, I have ran into a problem while sending mail to apple private relay email. We have built a mobile application where user can sign up through apple and they can sign up using hide-my-email feature. Which provides private relay address for us. Now we want to communicate with them using private relay mail address. The technology we are using to send emails are amazon SES, have done SPF, DMIK, DMARC and added domains in apple identity services for mail communication, passed an SPF check as well. But still mail is not getting delivered what am i doing wrong or apple doesn't support third party apps for sending emails to private relay? Is there any other way to achieve this please let me know Using the same body as attached in image is working fine for rest emails.

Hello everyone, I'm encountering a persistent 503 Server Temporarily Not Available error when trying to implement "Sign in with Apple" for my web application. I've already performed a full review of my configuration and I'm confident it's set up correctly, which makes this server-side error particularly confusing. Problem Description: Our web application uses Firebase Authentication to handle the "Sign in with Apple" flow. When a user clicks the sign-in button, they are correctly redirected to the appleid.apple.com authorization page. However, instead of seeing the login prompt, the page immediately displays a 503 Server Temporarily Not Available error. This is the redirect URL being generated (with the state parameter truncated for security): https://appleid.apple.com/auth/authorize?response_type=code&client_id=XXXXXX&redirect_uri=https%3A%2F%2FXXXXXX.firebaseapp.com%2F__%2Fauth%2Fhandler&state=AMbdmDk...&scope=email%20name&response_mode=form_post Troubleshooting Steps Performed: Initially, I was receiving an invalid_client error, which prompted me to meticulously verify every part of my setup. I have confirmed the following: App ID Configuration: The "Sign in with Apple" capability is enabled for our primary App ID. Services ID Configuration: We have a Services ID configured specifically for this. The "Sign in with Apple" feature is enabled on this Services ID. The domain is registered and verified under "Domains and Subdomains". Firebase Settings Match Apple Settings: The Services ID from Apple is used as the Client ID in our Firebase configuration. The Team ID is correct. We have generated a private key, and both the Key ID and the .p8 file have been correctly uploaded to Firebase. The key is not revoked in the Apple Developer portal. Since the redirect to Apple is happening with the correct client_id and redirect_uri, and the error is a 5xx server error (not a 4xx client error like invalid_client), I believe our configuration is correct and the issue might be on Apple's end. This has been happening consistently for some time. My Questions: What could be causing a persistent 503 Server Temporarily Not Available error on the /auth/authorize endpoint when all client-side configurations appear to be correct? What is the formal process for opening a technical support ticket (TSI) directly with Apple Developer Support for an issue like this? Thank you for any insights or help you can provide.

Hello, I am unable to configure Sign in with Apple on my developer account. Whenever I try to: Enable/disable the Sign in with Apple capability in my App ID, or Configure a Service ID for web authentication, the portal does not save my changes. In the browser developer console, I consistently see this error: Request URL: https://developer.apple.com/services-account/v1/bundleIds/XXXXXXXX Request Method: PATCH Status Code: 501 Not Implemented This happens across all browsers (Safari, Chrome, Incognito) and even after clearing cache. It affects my entire account, not just one App ID. I have already tried: Creating a new Service ID → still fails. Creating a new App ID → still fails. Re-enabling the capability → save does not work. Different browsers and devices → same result. Has anyone else experienced this issue, and is there a known fix? Or is this something that Apple Developer Support needs to resolve at the account level?

I set up "Sign in with Apple" via REST API according to the documentation. I can log in on my website and everything looks fine for the user. But I receive an email, that my "Sign in with Apple" account has been rejected by my own website. It states, I will have to re-submit my name and email address the next time I log in to this website. I don't see any error messages, no log entries, no HTTP errors anywhere. I also can't find anything in the docs, the emails seem to not be mentioned there, searching for anything with "rejected" in the forum did not yield any helpful result, because they are always about App entries being rejected etc. Did someone experience something similar yet? What's the reason, I'm getting these emails? I get them every time I go through the "Sign in with Apple" flow on my website again.

Confirmation on "Sign in with Apple JS" Web Implementation Compatibility Hello Developers We are trying to implement "Sign in with Apple JS" on our e-commerce website, which is built on a SaaS platform called Ticimax in Turkey. Our platform provider (Ticimax) claims that a web-based implementation of "Sign in with Apple" is not currently possible. They state this is due to "Apple's browser security policies" that prevent consistent and secure support across all major browsers, particularly Safari with its privacy features. Could you please confirm if there are any fundamental security policies or technical restrictions imposed by Apple that would prevent a standard, secure implementation of "Sign in with Apple JS" on a typical e-commerce website? We know many global websites use this feature successfully. We need to know if our provider's claim has a technical basis from Apple's perspective, or if this is a standard implementation challenge that developers are expected to handle (e.g., using pop-ups instead of redirects to comply with ITP). Any official clarification or documentation you can provide on this matter would be greatly appreciated. Thank you.

Hello, I’m trying to set up Sign In with Apple for my Firebase Authentication integration. Steps I followed: Created a Service ID in Apple Developer, e.g. com.example.myapp.signin. Tried to enable Sign In with Apple and configure the Web Authentication Configuration. Web Domain: myapp.firebaseapp.com Return URL: https://myapp.firebaseapp.com/__/auth/handler When I click Save, I get the following error in the browser console and a blank response page: Unsupported Request PATCH to http://developer.apple.com/services-account/v1/bundleIds/XXXXXXXX not supported. Reference #... What I have verified so far: My Apple Developer Program membership is active (paid). My App ID (e.g. com.example.myapp) exists in Identifiers. The App ID has Sign In with Apple capability checked. I need to link the Service ID with this App ID for Firebase web-based auth. Goal: Complete setup of Apple as a sign-in provider in Firebase Authentication. To do this, Apple requires me to add the Firebase return URL above, but the Developer Portal prevents saving with the 501 error. Has anyone else run into this, and is there a workaround (e.g. enabling via Xcode, App Store Connect, or other methods)? Is this a known bug with the Apple Developer Portal? Here is the screenshot of the error: And Response part: Thanks in advance!

We have been sending emails through Sparkpost via Braze inc. to the Apple Private Relay users with "@privaterelay.appleid.com" starting from around June 20th or so. Upon August 9th 06:00 UTC, we have noticed a sudden increase of "Hard Bounce" for nearly 20,000 users using the Apple's private relay email address, rendering the email sending useless for these customers. We have been constantly been able to send them emails, including just before this timeframe (e.g. August 9th 03:00 UTC), so it was a very sudden purge of the user data that has been done without our consent. From a business perspective, this hurts a lot for the un-sendable users since we have no way of contacting them if not for the private address. We are desperate to know what has happened for these customers that has been "hard bounced". We are suspecting that it should be tied to the private email and the users primary email (or user data's) tie in the Apple server being gone, but not sure enough since there is no such documentation nor any way to acknowledge what has happened anywhere. We will provide any information possible for resolving. Thank you.

I'm not able to download my Private key since Yesterday and I get the following error message when I click on "Download" Auth Key can only be downloaded once. This auth key has already been downloaded. I revoked all my existing keys and created new ones and I get the same error message. I tried all the mentioned solutions on this forum and StackOverflow like using Safari,turning off VPNs,removing spaces from Key name, using my iPhone, using a Mac, incognito/private mode on Windows Microsoft Edge, clicking done then pressing download after, right clicking on download Linked File as...nothing seems to work

I’m trying to update the Domains and Redirects section for my Services ID configuration in Apple Developer (for Sign in with Apple). When I add new domains and click Save, nothing happens. In the browser console, I see a network request that fails with: PATCH not supported What I’ve tried so far: Logging out/in and refreshing the page Clearing browser cache and cookies Trying in Safari, Chrome, and incognito mode Verifying domain formatting (HTTPS, no trailing slash, domain is live) The issue persists in all browsers I’ve tested. Request: Is this a known issue with the Developer portal, or is there an alternative method to update my Services ID domains? Any guidance would be appreciated. Thanks,

I can't find any documentation on design guidelines for "Login with Game Center" button. My app allows users to "Play as Guest" or "Login with Game Center". Since Apple provides somewhat strict guidelines for designing "Sign in with Apple" button, i was wondering how to design the button for Game Center login. Should i use Game Center icon. And will Apple review reject this?

I have two applications, and I recently decided to add the Apple Sign In feature. Initially, I configured it for one of the apps as the Primary ID for this feature. Everything worked well, and I decided to add it to the second app. I made a mistake and used the First app as Primary ID using the "Group with an existing primary App ID" flag. Now, when I sign in using the second app, I don't see it in the list of apps in iPhone Settings for Apple Sign In; I only see the primary app. And with that, I no longer see a prompt for sharing/hiding email, and I am unable to revoke credentials correctly. I decided to change the Second app's Sign-in config and set it as the Primary ID for the feature. I was hoping to get two apps independent for the SignIn. However, it doesn't seem to make a difference. The second app behaves the same way, as long as the first app used SignIn, the second one always thinks that the user has already used that feature and never shows the correct prompt. Is there something I missed after changing the Configuration?

I'm currently coding an application using Azure Entra External ID (B2C) with User Flows and multiple identity providers configured. So far, I’ve successfully linked Microsoft, Google, and Facebook. However, when configuring Apple as an identity provider, the User Flow fails with the following error: "invalid_request invalid web redirect url" Following the Microsoft Learn guide (https://learn.microsoft.com/en-us/entra/external-id/customers/how-to-apple-federation-customers), I completed the following: Create an Apple application Sign in to the Apple Developer Portal with your account credentials.

Client secret (.p8) key: The client secret key of the Apple application you created in the previous step. Select Save. You’ll see Apple listed as a configured identity provider. Add Apple identity provider to a user flow At this point, the Apple identity provider has been set up in your Microsoft Entra External ID, but it's not yet available in any of the sign-in pages. To add the Apple identity provider to a user flow: In your customer tenant, browse to Entra ID > External Identities > User flows. Select the user flow where you want to add the Apple identity provider. Under Settings, select Identity providers. Under Other Identity Providers, select Apple. Select Save. ❌ The Issue After completing all steps, Apple still fails during sign-in, while the other providers work correctly. The error message I receive is: "invalid_request invalid web redirect url" Request for Help I'm unsure where the misconfiguration may lie — whether it's with: The Return URLs entered in the Apple Developer portal, The Client ID or other fields in the Entra portal, Or something else I’ve overlooked. If anyone has successfully configured Apple ID federation with Azure Entra External ID (B2C) and encountered this error, I'd really appreciate any insights or suggestions. Thank you!

Our app uses Sign in with Apple. In recent weeks (or months), we've noticed that emails sent to @privaterelay.appleid.com addresses are not being delivered. We're not receiving any bouncebacks or error messages from the mail server, but the emails never reach the user's mailbox. We've also checked spam folders, with no luck. We have verified that our Email Sources are configured correctly in Apple Developer settings. Is there any way to debug or trace what might be happening with these messages? Thanks in advance!

Hi! I'm trying to add Sign in with Apple to my macOS app. I enabled this capability from the developer portal and created the corresponding certificate & provisioning profile (both of type Developer ID Application.) However, Xcode keeps prompting me that the profile doesn't support Sign in with Apple. If I enable Automatically manage signing from Xcode, I can build and run the app but not distribute. If I turn it off and use the profile I got, it just keeps showing the errors below and doesn't even let me build.

We implemented a feature to receive name and email address after Sign in with Apple, and it works perfectly in our testing. However, during the app review, they says it doesn't work, and the app is rejected. Why does it work differently?

Hi Community, We've implemented Sign In with Apple in our application. Our domains are properly registered in the developer console, but we're experiencing inconsistent email functionality with Apple's privacy email service. Some domains work correctly while others show delivery problems, even though all domains have identical configurations. Apple's console displays green verification status for all domains, yet testing reveals that emails to privacy-protected accounts don't arrive as expected. We're using SendGrid as our email service provider, and all domains have valid authentication records (SPF, DKIM, DMARC) in place. Has anyone encountered similar inconsistencies with Apple's privacy email service? Would appreciate any configuration tips or troubleshooting guidance. Thanks.

Dear Apple Developer Technical Support, We are currently following the official Apple documentation “TN3159: Migrating Sign in with Apple users for an app transfer” to carry out a Sign in with Apple user migration after successfully transferring several apps to a new developer account. Here is a summary of our situation: Under the original Apple developer account, we had five apps using Sign in with Apple, grouped under a shared primary app using App Grouping. Recently, we transferred three of these apps to our new Apple developer account via App Store Connect. After the transfer, these three apps are no longer associated with the original primary App ID. We reconfigured individual Services IDs for each app in the new account and enabled Sign in with Apple for each. More than 24 hours have passed since the app transfer was completed. Now we are attempting to follow the migration process to restore user access via the user.migration flow. Specifically, we are using the following script to request an Apple access token: url = "https://appleid.apple.com/auth/token" headers = {"Content-Type": "application/x-www-form-urlencoded"} data = { "grant_type": "client_credentials", "scope": "user.migration", "client_id": "com.game.friends.ios.toptop.sea", # New Services ID in the new account "client_secret": "<JWT signed with new p8 key>" } response = requests.post(url, headers=headers, data=data) However, the API response consistently returns: { "error": "invalid_client" } We have verified that the following configurations are correct: The client_secret is generated using the p8 key from the new account, signed with ES256 and correct key_id, team_id, and client_id. The client_id corresponds to the Services ID created in the new account and properly associated with the migrated app. The scope is set to user.migration. The JWT payload contains correct iss, sub, and aud values as per Apple documentation. The app has been fully transferred and reconfigured more than 24 hours ago. Problem Summary & Request for Support: According to Apple’s official documentation: “After an app is transferred, Apple updates the Sign in with Apple configuration in the background. This can take up to 24 hours. During this time, attempts to authenticate users or validate tokens may fail.” However, we are still consistently receiving invalid_client errors after the 24-hour waiting period. We suspect one of the following issues: The transferred apps may still be partially associated with the original App Grouping or primary App ID. Some Sign in with Apple configuration in Apple’s backend may not have been fully updated after the transfer. Or the Services ID is not yet fully operational for the transferred apps in the new account. We kindly request your assistance to: Verify whether the transferred apps have been completely detached from the original App Grouping and primary App ID. Confirm whether the new Services IDs under the new account are fully functional and eligible for Sign in with Apple with user.migration scope. Help identify any remaining configuration or migration issues that may cause the invalid_client error. If necessary, assist in manually ungrouping or clearing any residual App Grouping relationships affecting the new environment. We have also generated and retained the original transfer_sub identifiers and are fully prepared to complete the sub mapping once the user.migration flow becomes functional. Thank you very much for your time and support!
