Performing a Sale Transaction

Follow these steps to perform a sale transaction.

Create a

TransactionParameters

object and provide the required information for the payment.

Retrieve the

transactionIntent

from the

mposUi

object and use the

startActivity

method to initiate the transaction flow.

ADDITIONAL INFORMATION

val transactionParameters = TransactionParameters.Builder()
            .charge(BigDecimal("1.00"), Currency.EUR)    
            .subject("POSsaleID")
            .customIdentifier("yourReferenceForTheTransaction")
            .build()

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

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

onActivityResult

is triggered, which 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()
            }
