Stand-Alone Credit

Use the information in this section to process a stand-alone credit. This type of transaction enables you to issue a credit without referencing a previous transaction. To complete the credit, the customer must present their payment card at the time of processing.

When processing a stand-alone credit, there is no limit on the credit amount because the transaction does not reference the original purchase. To help manage risk, it is recommended to use a refund transaction whenever possible. For more information, see Refund.

Follow these steps to process a stand-alone credit.

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(BigDecimal("1.00"), Currency.EUR)     
            .customIdentifier("yourReferenceForTheTransaction")  
            .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.

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_TRANSACTION_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
