iOS DeviceCheck API call returning 400 all the time
Hi, I'm getting 400 Missing or badly formatted authorization token everytime I call the following API from my local Server ( I tried calling this API from my app itself as well) curl --location 'https://api.development.devicecheck.apple.com/v1/query_two_bits' \ --header 'Authorization: Bearer <<JWT-token>>' \ --header 'Content-Type: application/json' \ --data '{ "device_token": Token_fetched_from_Device_Check, "transaction_id":"c6bdb659-0ee6-443d-88cb-a8f036dfc551", "timestamp": 1721300244267 }' "device_token" - I have generated from DeviceCheck framework JWT-token - I generated using key from .p8 file generated from Apple developer portal, keyId of the same and the team Id ( I have individual account) IMP Points- I have created this .p8 file from apple developer account, and I did enable Device check option while creating the key. I also tried calling this API after 7 hours ( and more then that as well) of creating key from the developer portal as I have read somewhere that the key gets activated after few hours. I understand (again read somewhere) that the token created by DeviceCheck framework has some expiration time so I tried with freshly created token several times as well. This is how I'm generating token using DeviceCheck - if curDevice.isSupported{ DCDevice.current.generateToken { (data, error) in if let data = data { } } } JWT token generation - func createJWTToken(privateKey: String, keyID: String, teamID: String) -> String? { // Set up the JWT header var jwtHeader = Header() jwtHeader.kid = keyID // Set up the JWT claims let jwtClaims = MyClaims(iss: teamID, iat: Date()) // Create the JWT var jwt = JWT(header: jwtHeader, claims: jwtClaims) // Convert the private key to Data guard let privateKeyData = Data(base64Encoded: privateKey) else { print("Invalid private key") return nil } // Sign the JWT let jwtSigner = JWTSigner.es256(privateKey: privateKeyData) do { let signedJWT = try jwt.sign(using: jwtSigner) return signedJWT } catch { print("Failed to sign JWT: \(error)") return nil } } But no luck, please suggest something. any sort of help is much appreciated. Thank you
