Hi there,

I have a payment gateway that consists of two "callbacks":

1. The initial callback for the user using GetReturnValuesFromUrl

2. A call back service that is called minutes or hours later with an up-to-date status of the payment.

I am having some troubles finding out when to update which value, and when to use UpdateGateway result and so on. Here are the options that seem to be related to the order and its status:

order.Complete
order.Errors
order.Gateway.SetOrderComplete
order.GatewayPaymentStatus
order.GatewayResult
order.GatewayTransactionProblems
order.TransactionAmount
order.TransactionNumber
order.TransactionPayGatewayCode
order.TransactionStatus
order.TransactionType
order.TransactionValue
order.UpdateGatewayResult

Is there any guidance on when to set / call what? The API sample doesn't go into this. Additionally, I used Reflector to dig into the existing V1 gateways, and all seem to be doinf something else ;-)

Currently, I have this:

1. User call backpage (e.g. step 6)

order.TransactionType = transactionTypeFromRequest;
order.TransactionNumber = transactioNumberFromRequest;
order.Save();
order.GatewayResult = aBunchOfresultXml;
order.TransactionNumber = transactioNumberFromRequest;
order.UpdateGatewayResult(isComplete);

2. The call back page:

order.TransactionNumber = item.pspReference;
order.PaymentMethod = item.paymentMethod;
order.StateID = AppConfiguration.OrderStates.OrderStateBetaald; // "OS2" for Paid or OS3 for cancelled
order.GatewayResult = someXmlFromTheCallback;
order.TransactionStatus = ConvertAdyenCodeToDwCode(item.eventCode); // Something like "Paid" or "Rejected"
order.Complete = isPaid;
order.GatewayTransactionProblems.Clear(); // Need to do this to clear previous errors
order.GatewayPaymentStatus = ConvertAdyenCodeToDwCode(item.eventCode); // Something like "Paid" or "Rejected"
order.UpdateGatewayResult(true);
order.Save();

As you can see, there's some duplication between the two, and I am overwriting stuff like TransactionNumber and GatewayResult.

Can anyone make some sense of this and tell me / show me when to set and use what? Most of the API documentation for the properties seem to be automatically generated and contain the quite useless "Gets or sets the Property Name" comments... ;-)

Kind regards,

Imar
