Authorize.Net AIM事务超时解决方法？

Question

我为authorize.NET AIM网关auth_capture事务编写了以下代码：

    try
                {
                    if (transactionAmount == 0)
                    {
                        Logger.WriteInfo("$0 transaction needs no payment Gateway Transaction ");
                    }
        else 
        {
            //This function sends auth_capture request and processes payment based on transaction parameters.
                        TransactionResponse transactionResponse = ProcessPayment(dist, fee);

                        transactionID = transactionResponse.TransactionID;
                        transactionStatus = transactionResponse.Status;
                        serverResponse = transactionResponse.ServerResponse;
                    }
                }
                catch (TimeoutException tex)
                {
                    context.Dispose();
                    Logger.WriteError(ex.ToString());
                    Master.ErrorMessage = ConfigurationManager.AppSettings["TRANSACTION_TIMEOUT_MESSAGE"];
                    IEUtils.SendExceptionMail(ex.tex, ConfigurationManager.AppSettings["TRANSACTION_TIMEOUT_EMAIL_SUBJECT"]);
                    Logger.WriteError(ex.ToString());

                }
                catch (Exception ex)
                {
                    context.Dispose();
                    Logger.WriteError(ex.ToString());
                    Master.ErrorMessage = ex.Message;
                    return;
                }

情况是，如果发生超时，我们如何才能看到交易是否已经发生，如果是，那么交易ID是什么？有一些方法可用于获得已结算/未结算的交易，但识别最近的交易需要多次api调用，这也是有风险的。在authorize.Net网关事务请求超时后，最有效的解决方法是什么？
