Sale with Installment Details {#ttp-payment-txn-sale-installment-details-task}
==============================================================================

Use this information to process a sale with installment details. This transaction includes the required installment payment details in the payment request.
IMPORTANT This transaction is available only in the Latin American and Caribbean (LAC) region.  
Follow these steps to process a sale with installment details.

1. Create an `InstallmentDetails` object and set one ore more of the installment fields.

   ```
   // Set value of the builder to the number of installments
   val installmentDetails = InstallmentDetailsBuilder(5)
           // Set to PlanType.ISSUER_FUNDED for issuer funded plans
           .planType(PlanType.MERCHANT_FUNDED)
           .includesInterest(true)
           .governmentPlan(true)
           .build()
   ```
2. Create a `TransactionParameters` object and provide the required information for the payment.

3. 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")
               .installmentDetails(installmentDetails)
               .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` 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. You can get the full transaction object by retrieving the `latestTransaction` from the `mposUi` object.

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