Capture {#pax-aio-payment-txn-capture-task}
===========================================

Use this information 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` variable 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 complete and the Summary screen is dismissed, the `onActivityResult` method is triggered. This action returns information 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() 
               } 
           } 
       } 
   }
   ```
4. Get the full transaction object by retrieving the `latestTransaction` property from the mposUi object.

   ```
   val transactionObject = mposUi.latestTransaction
   ```
