Sale with On-Receipt Tipping {#pax-aio-payment-txn-sale-on-receipt-tip-intro}
=============================================================================

Use this information to process a sale with on-receipt tipping. After the original transaction amount is pre-authorized, the customer writes the tip or total amount on the printed receipt. A follow-on tip adjust request must be sent within 24 hours to capture the transaction. For more information, see [Tip Adjust](/docs/vas/en-us/pax-all-in-one/integration/all/na/pax-all-in-one/pax-aio-payment-txn-intro/pax-aio-payment-txn-sale-on-receipt-tip-intro/pax-aio-pymnt-txn-tip-adj-onreceipt-sale-intro.md "").
By using this feature, you assume the risk of the overcapture being declined and increased chargebacks. Only use this feature when required. The recommendation is to process a sale with on-reader tipping whenever possible. For more information, see [Sale with On-Reader Tipping](/docs/vas/en-us/pax-all-in-one/integration/all/na/pax-all-in-one/pax-aio-payment-txn-intro/pax-aio-payment-txn-sale-on-reader-tip-task.md "").

Process a Sale with On-Receipt Tipping {#pax-aio-payment-txn-sale-on-receipt-tip-task}
======================================================================================

After completing a sale with on-receipt tipping transaction, a follow-on tip adjust request must be sent within 24 hours to capture the transaction. For more information, see [Tip Adjust](/docs/vas/en-us/pax-all-in-one/integration/all/na/pax-all-in-one/pax-aio-payment-txn-intro/pax-aio-payment-txn-sale-on-receipt-tip-intro/pax-aio-pymnt-txn-tip-adj-onreceipt-sale-intro.md ""). Follow these steps to process a sale with on-receipt tipping.

1. Create a `TransactionParameters` object and provide the required information for the payment.

2. Retrieve the `transactionIntent` variable from the `mposUi` object and use the `startActivity` method to initiate the transaction flow.

   ```
   val transactionParameters = TransactionParameters.Builder()
               .charge(BigDecimal("50.00"), Currency.USD)    
               .customIdentifier("yourReferenceForTheTransaction")
               .autoCapture(false)
               .TipAdjustable(true)
               .build()

   val transactionIntent = mposUi.createTransactionIntent(transactionParameters)
   startActivityForResult(transactionIntent, MposUi.REQUEST_CODE_PAYMENT)
   ```
3. 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()
               }
           }
       }
   }
   ```
4. Get the full transaction object by retrieving the `latestTransaction` property from the mposUi object.  
   


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




Tip Adjust {#pax-aio-pymnt-txn-tip-adj-onreceipt-sale-intro}
============================================================

Use this information to process a tip adjust. This is a required follow-on transaction after processing a sale with on-receipt tipping. The tip adjust request must be sent within 24 hours to capture the transaction.  
After the original sale transaction is pre-authorized, the customer writes the tip or total amount on the printed receipt. The tip adjust request must be submitted with the tip amount or with `0`, if no tip was provided. The tip adjust amount is limited to 20% of the original transaction amount. Requests for higher amounts will be rejected. A follow-on tip adjust request is then sent to capture the additional tip amount. This transaction is also called an *overcapture*.
