                   .addLegDetails(
                       listOf(

                               .fare(BigDecimal("450.00"))

                               .fee(BigDecimal("25.00"))
                               .flightNumber("1234")
                               .originatingAirportCode("SFO")
                               .stopoverCode(StopoverCode.NO_STOPOVER)
                               .tax(BigDecimal("38.00"))
                       )
                   )
                   .build()
           )
           .ancillaryDetails(
               AncillaryDetailsBuilder()
                   .connectedTicketNumber("0149876543210")
                   .creditReasonIndicator(CreditReasonIndicator.OTHER)
                   .feeDescription("Checked baggage")
                   .passengerName("Jane Doe")
                   .ticketNumber("0141234567890")
                   .addServiceDetails(
                       listOf(
                           ServiceDetailsBuilder()
                               .categoryCode("BAGO")
                               .subcategoryCode("CHKD")
                               .feeAmount(BigDecimal("35.00"))
                               .feeCode("0DB")
                       )
                   )
                   .build()
           )
           .build()
   ```
2. Create a `TransactionParameters` object and provide the required information for the payment.

3. Retrieve the `transactionIntent` variable 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")
               .additionalDetails(airlineDetails)
               .build()

   val transactionIntent = mposUi.createTransactionIntent(transactionParameters)
   startActivityForResult(transactionIntent, MposUi.REQUEST_CODE_PAYMENT)
   ```
4. After the transaction is complete and the Summary screen is dismissed, the `onActivityResult` method 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()
               }
           }
       }
   }
   ```
5. Get the full transaction object by retrieving the `latestTransaction` property from the `mposUi` object.

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