Refund

Use the information in this section to process a refund by referencing the original transaction. You can issue refunds for either the full amount or a partial amount of the original transaction. Stand-alone credits are also supported and can be processed independently of a prior transaction. For more information, see Stand-Alone Credit.

Follow these steps to process a refund.

Create a

TransactionParameters

object and provide the required information for the payment.

Retrieve the

transactionIntent

variable 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, the

onActivityResult

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

override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) { 
    super.onActivityResult(requestCode, resultCode, data) 
  
    if (requestCode == MposUi.REQUEST_CODE_PAYMENT) { 
        when (resultCode) { 
            // Result code from a successful transaction 
            MposUi.RESULT_CODE_APPROVED -> { 
        val transactionIdentifier = data?.getStringExtra(MposUi.RESULT_EXTRA_TRAN
SACTION_IDENTIFIER) 
        Toast.makeText(findViewById(android.R.id.content),"Transaction approved!\nIdentifier: $transactionIdentifier",  
Toast.LENGTH_LONG).show() 
            } 
           // Result code from a declined, aborted or failed transaction 
          MposUi.RESULT_CODE_FAILED -> { 
        Toast.makeText(findViewById(android.R.id.content), "Transaction was declined, aborted, or failed",  
Toast.LENGTH_LONG).show() 
            } 
        } 
    } 
}

Get the full transaction object by retrieving the

latestTransaction

from the mposUi object.

val transactionObject = mposUi.latestTransaction
