Performing a Linked Refund

This section describes how to perform a linked refund using a reference to the original transaction for a full or partial transaction amount. Standalone credits are also supported in this Acceptance Devices solution. For more information, see Performing a Standalone Credit.

Follow these steps to perform a linked refund:

Create a

TransactionParameters

object and provide the required information for the payment.

Retrieve the

transactionIntent

from the

mposUi

object and use the

startActivity

method to initiate the transaction flow.

val transactionParameters = TransactionParameters.Builder() 
            .refund(“transactionIdentifier”) 
            //Specify amount and currency for partial refunds 
            //.amountAndCurrency(BigDecimal(1.00), Currency.EUR) 
            .build() 

val transactionIntent = mposUi.createTransactionIntent(transactionParameters) 
startActivityForResult(transactionIntent, MposUi.REQUEST_CODE_PAYMENT)

After the transaction is completed and the Summary screen is dismissed,

onActivityResult

is triggered. This action returns information about the last transaction.
