Sale

This section describes how to process a sale transaction. This type of transaction combines an authorization and a capture into a single transaction.
Follow these steps to process a sale:
  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()
            .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, 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_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()
            }
        }
    }
}
  4. You can get the full transaction object by retrieving the
    latestTransaction
     from the
    mposUI
     object.
    val transactionObject = mposUi.latestTransaction
