Check Transaction Status {#pax-aio-payment-txn-check-txn-status-task}
=====================================================================

Use this information to request a check transaction status. This transaction enables you to retrieve response data for a transaction that was lost or timed out. You must have the `transactionIdentifier` value for the transaction that you want to check. When the check transaction status request is complete, the transaction details show on the Summary screen.  
Follow these steps to request a check transaction status.

1. Access the `transactionIdentifier` value in the `onActivityResult` method of the original transaction.

2. Retrieve the transaction `summaryIntent` value from the `mposUi` object.

3. Use the `startActivity` method to initiate the Summary screen.

   ```
   val summaryIntent = mposUi.createTransactionSummaryIntent(transactionIdentifier = "transactionIdentifier")
   startActivityForResult(summaryIntent, MposUi.REQUEST_CODE_SHOW_SUMMARY)
   ```
4. After 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)
       // Result code from closing the summary screen
       if (resultCode == MposUi.RESULT_CODE_SUMMARY_CLOSED) {
           // Accessing status from the transaction that was just queried
           val transactionStatus = mposUi.latestTransaction?.status
           Toast.makeText(activity, "Summary closed. Transaction status: $transactionStatus", Toast.LENGTH_SHORT).show()  
       }
   }
   ```
5. Get the full transaction object by retrieving the `latestTransaction` property from the mposUi object.  
   


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