Performing a Sale

This section describes how to perform a sale transaction. This type of transaction combines an authorization and a capture into a single transaction.
Follow these steps to perform a sale:
  1. Create a
    TransactionParameters
     object and provide the required information for the payment.
  2. Retrieve the
    transactionIntent
     from the
    mposUi
     object and use the
    startActivity
     method to initiate the transaction flow.
    val transactionParameters = TransactionParameters.Builder()
            .charge(BigDecimal("1.00"), Currency.EUR)    
            .customIdentifier("yourReferenceForTheTransaction")
            .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
     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()
            }
        }
    }
}
