@Lfc Did you find the exact root cause of your error? { statusCode = 500; statusMessage = 'Broker Service Response exception'; } I am getting the same error, and verified my encryption using Test Vectors. Even after decrypting both payloads, one documented encrypted data and the second my encrypted data, I am not finding any issue with encryption, as mentioned. It would be helpful for me if you can explain the exact root cause of this issue. .

@VidhyaSri21 , I have also been facing the same encryption issue as on my Feedback assistant . I got an update from DTS that "The error is due to bad encryption. Please review whether your cryptography matches the expectations outlined in the Getting Started with Apple Pay: In-App Provisioning, Verification, Security, and Wallet Extensions (v4)" guide. I have matched my encryption using test vectors, and the output matches my code's output. Can you guide me, how did you get the exact root cause of your encryption?

Nope! I am still waiting for a reply from Apple.
