Troubleshooting for Apple Pay integration

Learn how to solve common problems that might occur when you are integrating Apple Pay payment method.

Apple pay payment type creation fails

Problem:

The Apple Pay type creation fails and the Unzer API returns Failed to decrypt ApplePay data from merchant s-pub-xxx as the merchant message.

Solution:

Make sure you transmit correct and complete payment data. You should provide the data received from Apple Pay, in the onpaymentauthorized event. The payment data must be in JSON format with the following structure:

{
  "version": "EC_v1",
  "data": "{data}",
  "signature": "{signature}",
    "header": {
      "ephemeralPublicKey": "{ephemeralPublicKey}",
      "publicKeyHash": "{publicKeyHash}",
      "transactionId": "{ApplePayTransactionId}"
    }
}

For more information on payment token format, see the Apple Pay documentation.
