Processing a Capture

This section describes how to capture a pre-authorized transaction. The capture request references the approved pre-authorization request.
Follow these steps to process a capture:
  1. Create a
    TransactionParameters
     object and provide the required information for the payment.
  2. Retrieve the
    transactionIntent
     value from the
    mposUI
     object and use the
    startActivity
     method to initiate the transaction flow.
    val transactionParameters = TransactionParameters.Builder()
           .capture("transactionIdentifier") 
        // Specify amount and currency for partial captures
        // .amountAndCurrency(BigDecimal("1.00"), Currency.EUR)
           .build() 

val transactionIntent = mposUi.createTransactionIntent(transactionParameters) 
startActivityForResult(transactionIntent, MposUi.REQUEST_CODE_PAYMENT)
  3. After the transaction is completed and the Summary screen is dismissed,
    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() 
            } 
        } 
    } 
}
  4. You can get the full transaction object by retrieving the
    latestTransaction
     value from the
    mposUI
     object.
    val transactionObject = mposUi.latestTransaction
