    String signedRenewalInfo = decodedPayload.getData().getSignedRenewalInfo();
    String signedTransactionInfo = decodedPayload.getData().getSignedTransactionInfo();

    JWSRenewalInfoDecodedPayload jwsRenewalInfoDecodedPayload = notificationDecoder.decodeRenewalInfo(signedRenewalInfo);
    JWSTransactionDecodedPayload jwsTransactionDecodedPayload = notificationDecoder.decodeTransaction(signedTransactionInfo);
