Set custom values for gateway-specific fields

Optimizely Configured Commerce's Payment Service lets you create a provider to configure specific fields for your gateway.

The following example takes the transaction type and dictionary of custom parameters as input parameters.

The transaction type is set automatically and depends on the current transaction's type.

The parameters are passed from the properties of the AddPaymentTransactionParameter object, which you can populate in the ProcessCreditCardTransactions handler.

There are two ways to customize gateway-specific fields:

• Static fields – Create a custom GatewaySpecificFieldsProvider.
• Flexible fields – Create a custom GatewaySpecificFieldsProvider and override the ProcessCreditCardTransactions handler and pass custom string values through AddPaymentTransactionParameter.

Structure of the GatewaySpecificFields object

GatewaySpecificFields is the outer container object. It has a property called GatewaySpecifics, which is a list of GatewaySpecific objects.

GatewaySpecific represents settings or parameters specific to a single payment gateway. In this example, the GatewayName is stripe_payment_intents, meaning these settings are for the Stripe Payment integration. Fields is a list of key-value pairs (GatewaySpecificField) that define specific options or behaviors for this gateway.

GatewaySpecificField represents a single setting for the payment gateway. In this example, Name is request_multicapture, and Value is if_available.

Example

public class CustomGatewaySpecificFieldsProvider : IGatewaySpecificFieldsProvider  
{  
    public GatewaySpecificFields GetGatewaySpecificFields(  
        TransactionType transactionType,  
        IDictionary\<string, string> parameters  
    )  
    {  
        return new GatewaySpecificFields  
        {  
            GatewaySpecifics = new List<GatewaySpecific>()  
            {  
                new GatewaySpecific  
                {  
                    GatewayName = "stripe_payment_intents",  
                    Fields = new List<GatewaySpecificField>  
                    {  
                        new GatewaySpecificField  
                        {  
                            Name = "request_multicapture",  
                            Value = "if_available"  
                        }  
                    }  
                }  
            }  
        };  
    }
