I am asking about the apple Sign in implementation. ▫️ problems eas local build or test flight, I get a “Could not complete registration” message. When I check the console, I see the following error message. akd SRP authentication with server failed! Error: Error Domain=com.apple.AppleIDAuthSupport Code=2 UserInfo={NSDescription=<private>, Status=<private>} ▫️ Assumption ・Developed with Expo ・"expo-apple-authentication":"^7.2.4" ・Two apps are developed at the same time, using supabase, firebase, but both have the same error ・On Xcode, on app ids, apple sign in capability is turned on ・Service ids is set to domain, return url ・keys is created ・Internal test of testfligt is set to deliver

Since a few days, we are hitting AuthorizationError 1000 / 1001 whenever we try to use Sign in with Apple for a new app. We have added entitlements to the app in both release and debug, and setup the services id. Many other devs are complaining about the same issue lately, and it's possible to reproduce on a fresh app id, see this thread: https://www.reddit.com/r/flutterhelp/comments/1lf6kmq/sign_in_with_apple_signup_not_completed

I am implementing Apple Sign-In for a multi-platform application, specifically for the web component using the REST API flow. I am encountering an invalid_request Invalid web redirect url error when attempting to use a newly registered redirect URL. Here are the details: Original Test URL: I initially registered a redirect URL, let's call it [Your Original Test Redirect URL, e.g., https://test.yourdomain.com/auth/callback], for testing purposes. This URL worked correctly. New Service URL: I then registered a second redirect URL, [Your New Service Redirect URL, e.g., https://www.yourdomain.com/auth/callback], intended for my production service. This URL was registered approximately 5 days ago (including the weekend). The Problem: The new service URL ([Your New Service Redirect URL]) is still not working and consistently returns the invalid_request Invalid web redirect url error. Puzzling Behavior: Furthermore, I have since deleted the original test URL ([Your Original Test Redirect URL]) from the Service ID configuration in the Apple Developer portal. However, the deleted test URL still appears to function correctly when I use it. This situation is highly confusing: The newly registered URL is not working after 5 days, while the URL I have deleted from the configuration is still operational. The Service ID in question is [Your Service ID, e.g., com.yourdomain.service]. Could you please investigate why the new redirect URL ([Your New Service Redirect URL]) is not becoming active and is returning the invalid_request error, and also explain why the deleted URL ([Your Original Test Redirect URL]) remains functional? Any guidance or assistance you can provide to resolve this issue with the new URL would be greatly appreciated. Thank you for your time and support. Sincerely, I have the exact same problem. The newly registered URL is not working after 5 days, while the URL I have deleted from the configuration is still operational. In addition to the above problem, I also get a response of 'invalid_client' when I newly register a service in configuration. Please check it out as it needs to be resolved quickly.

Hi, I've been developing an app with a server. I'm hosting the server on an IPv6-ONLY network that's hidden behind the CloudFlare, so it works flawlessly from the clients point of view, but if server needs to access external resources, they need to be accessible over IPv6. As it turns out, appleid.apple.com doesn't support IPv6, and the Sign In with Apple happens with the help of my server. So, I can't sign users in as Apple doesn't support IPv6 traffic on appleid.apple.com. Are there any plans to support IPv6 in the near future, or should I work on the networking setup to enable IPv4 just for the Apple SSO? Or maybe there's a clever workaround I'm missing?

Hello. I have issue with implementing "Sign in with Apple" on my website. As folow, I have created: App ID identifier: com.livnobus.app (G2F5N5UHYZ) Service ID identifier: com.livnobus.client (B25ZN8P84U) with option enabled "Sign in with Apple" and configuration (Primary App ID and Webiste URLs) Key ID: 43N8XKUW7S with option enabled "Sign in with Apple" and configuration (Primary App ID and Grouped App Ids) When I click "Sign in with Apple" on my website (https://dev.livnobus.com/auth/login), system redirect me to https://appleid.apple.com/ and error show "invalid_client". Redirect URL on my web site is: https://appleid.apple.com/auth/authorize?client_id=com.livnobus.client&redirect_uri=https%3A%2F%2Fdev.livnobus.com%2Fauth%2Fapple%2Fcallback&scope=name%20email&response_type=code&response_mode=form_post&state=eGAgdpLrvskJc26RbTizc9TGwxnL6KAEJOf68pmO&nonce=e7c7a242-1977-47ea-9013-98820c24bfba.eGAgdpLrvskJc26RbTizc9TGwxnL6KAEJOf68pmO There was old Service ID identifier com.livnobus.app-client, for which I lost private KEY, so I have created new one: com.livnobus.client With old Service ID com.livnobus.app-client, https://appleid.apple.com/ shows me Apple form for sign in, but with new Service ID com.livnobus.client there is error "invalid_client" https://appleid.apple.com/auth/authorize?client_id=com.livnobus.app-client&redirect_uri=https%3A%2F%2Fdev.livnobus.com%2Fauth%2Fapple%2Fcallback&scope=name%20email&response_type=code&response_mode=form_post&state=eGAgdpLrvskJc26RbTizc9TGwxnL6KAEJOf68pmO&nonce=e7c7a242-1977-47ea-9013-98820c24bfba.eGAgdpLrvskJc26RbTizc9TGwxnL6KAEJOf68pmO These changes I have made last Friday, and since then I can't use "Sign in with Apple" on my website. Thanks!

On Thursday, June 12, 2025, Sign in with Apple was impacted by an incorrect subdomain defined in its /.well-known/openid-configuration file. The JSON returned incorrectly provided https://account.apple.com instead of the expected https://appleid.apple.com. For Sign in with Apple, the value for the issuer (iss) claim in the user's identity token is https://appleid.apple.com. Additionally, if your clients use the Sign in with Apple REST API, the following endpoints should be used for each request: https://appleid.apple.com/auth/authorize https://appleid.apple.com/auth/token https://appleid.apple.com/auth/revoke https://appleid.apple.com/auth/keys This issue with the /.well-known/openid-configuration file was resolved the same day. Use the URL below to confirm the expected subdomain is provided, as needed: https://appleid.apple.com/.well-known/openid-configuration Cheers, Paris X Pinkney |  WWDR | DTS Engineer

On Wednesday, June 18, 2025, Sign in with Apple was impacted by a configuration issue which affected some developer accounts that created new app or Services ID configurations, or edited existing configurations, resulting in the following errors: invalid_client response error returned by the authentication, token validation/revocation, and user migration requests "Sign Up Not Completed" (or equivalent) error presented from the Authentication Services framework. On Monday, June 23, 2025, this issue was resolved. Please retry the Sign in with Apple flows in your Sign in with Apple enabled apps and websites to confirm your developer account configuration has been fixed. Please let us know if you can still reproduce this issue with your developer account. If so, follow the steps outlined in the post below: Gathering required information for troubleshooting Sign in with Apple authorization and token requests https://developer.apple.com/forums/thread/762831 Finally, reply (not comment) with your Feedback ID on either of the posts below: https://developer.apple.com/forums/thread/789011 https://developer.apple.com/forums/thread/789132 Cheers, Paris X Pinkney |  WWDR | DTS Engineer

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, 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.

As I had mentioned earlier, I was facing two issues after the initial update, but I’m happy to inform you that both of those issues have now been resolved. However, after updating to iOS 26.0 (23A5297m), I’ve started experiencing a new issue related to overheating. Since yesterday, my iPhone has been getting extremely hot while charging. It also became very hot after clicking just a few photos. The same heating issue occurred again today during charging. This problem only started after the latest update. Kindly look into this issue and advise on how to resolve it.

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?

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.

We are implementing authentication login in our iOS mobile application, and during the sign-in/sign-out process, a native system popup appears with the following message: "This allows the app and website to share information about you." This popup interrupts the user experience, and we are concerned it may cause confusion for end users and negatively impact the adoption of our login flow. We would like clarification on the following points: What triggers this popup during the authentication process? Are there any recommended configurations or approaches to suppress or avoid this dialog? If the popup cannot be avoided, what best practices are suggested to ensure a clear and seamless user experience? Our objective is to provide a smooth, user-friendly authentication flow without unexpected system interruptions.

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.

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.

Hey folks, I'm seeing an issue where my iOS app is getting an "unknown" error when US users try to sign in with Apple. It works fine for users in other countries like the UK, Singapore, and Taiwan. Could it be related to my developer account not being based in the US? Or have I missed something in my settings? Thanks in advance!

Hi, I followed step by step documentation to implement SignIn with Apple in iOS/Android application. I created an AppId com.nhp.queenergy, a related ServiceId com.nhp.queenergy.apple, and a KeyId. Authorization request is correctly performed by using ServiceId as client_id and my backend redirect_uri I receive code on my backend Token request is performed by using ServiceId as client_id, same redirect_uri, the code I have just received and the client_secret as JWT signed with my .p8 certificate with the following decoded structure Header { "kid": , "typ": "JWT", "alg": "ES256" } Payload { "iss": , "sub": "com.nhp.queenergy.apple", "aud": "https://appleid.apple.com", "exp": 1756113744, "iat": 1756111944 } I always receive "invalid_grant" error without any further error description. Moreover the error is always the same even though I use any fake string as client secret. If the code expires, as expected the error changes by adding "The code has expired or has been revoked." I really don't know how to solve this issue Best regards

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 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.
