After an app transfer, I'm reached this point in this article, and I need to check if the Sign In with Apple ID users I've migrated have the "transferred" status. This articles provides you with Swift code to check this status; does anyone know if there's a way to access this info using the Apple ID REST API, preferably with a curl command? Or do I specifically need to check this info on my app? Here's the swift code I'm talking about: let request = ASAuthorizationAppleIDProvider().createRequest() // Specify the current user identifier here. request.user = "User Identifier" let controller = ASAuthorizationController(authorizationRequests: [request]) controller.delegate = self controller.presentationContextProvider = self controller.performRequests()

We're preparing to migrate our Apple Sign-In users for an upcoming app transfer. Following this guide, we're currently stuck on the first curl command: curl -v POST "https://appleid.apple.com/auth/token" \ -H 'Content-Type: application/x-www-form-urlencoded' \ -d 'grant_type=client_credentials' \ -d 'scope=user.migration' \ -d 'client_id=CLIENT_ID' \ -d 'client_secret=CLIENT_SECRET_ISSUED_BY_TEAM_A' Specifically, we're having issues generating the client secret, specified here. We're using a Node.js script to generate the script; initially I realized that the private key I was signing the JWT with was wrong (I was using the App Store Connect API team key instead of a private key for use with Account & Organization Data Sharing). Every time we try entering this curl command: curl -v POST "https://appleid.apple.com/auth/token" \ -H 'Content-Type: application/x-www-form-urlencoded' \ -d 'grant_type=client_credentials' \ -d 'scope=user.migration' \ -d 'client_id=com.jumbofungames.platMaker' \ -d 'client_secret=$(node clientsecret_jwt2.js)' Where $(node clientsecret_jwt2.js) is the command to generate the client secret; we get this error: < HTTP/1.1 400 Bad Request < Server: Apple < Date: Mon, 19 Aug 2024 15:41:31 GMT < Content-Type: application/json;charset=UTF-8 < Content-Length: 49 < Connection: keep-alive < Pragma: no-cache < Cache-Control: no-store < * Connection #1 to host appleid.apple.com left intact {"error":"invalid_client","email_verified":false}% Here is the script we are using to generate the Client Secret (JWT), with some variables using placeholders for privacy: const fs = require('fs'); const jwt = require('jsonwebtoken'); // npm i jsonwebtoken // You get privateKey, keyId, and teamId from your Apple Developer account const privateKey = fs.readFileSync("./AuthKey_ABCDEFG123.p8") // ENTER THE PATH TO THE TEAM KEY HERE (private key file) const keyId = "API_KEY"; // ENTER YOUR API KEY ID HERE const teamId = "TEAM_ID"; // ENTER YOUR TEAM ID HERE const clientId = "com.companyname.appname"; // ENTER YOUR APP ID OR SERVICES ID HERE (This is the client_id) // Time settings (in seconds) let now = Math.round((new Date()).getTime() / 1000); // Current time (seconds since epoch) let nowPlus6Months = now + 15776999; // 6 months from now (maximum expiration time) let payload = { "iss": teamId, // The Team ID associated with your developer account "iat": now, // Issued at time "exp": nowPlus6Months, // Expiration time (up to 6 months) "aud": "https://appleid.apple.com", // Audience "sub": clientId // The App ID or Services ID } let signOptions = { "algorithm": "ES256", // Algorithm for signing (ECDSA with P-256 curve and SHA-256 hash algorithm) header : { "alg": "ES256", // Algorithm in the header "kid": keyId, // Key ID in the header "typ": "JWT" // JWT type } }; // Generate the JWT (client_secret) let clientSecret = jwt.sign(payload, privateKey, signOptions); console.log(clientSecret); module.exports = clientSecret; If anyone has run into similar issues using this API or could shed some light on what could be going wrong, please let us know — we're at a bit of a loss here.
