Incremental Authorization

Use this information to process an incremental authorization. An incremental authorization is used after an approved pre-authorization to increase the authorized amount before capture.

Follow these steps to process an incremental authorization.

Create a

TransactionParameters

object and provide the required information for the payment.

Retrieve the

transactionIntent

value from the

mposUi

object and use the

startActivity

method to initiate the transaction flow.

val transactionParameters = TransactionParameters.Builder() 
            .incrementalAuthorization("transactionIdentifier") 
            .amountAndCurrency(BigDecimal("1.00"), Currency.EUR) 
            .build() 

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

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

onActivityResult

method is triggered. This action returns information about the previous 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

value from the mposUi object.

val transactionObject = mposUi.latestTransaction
