Check Transaction Status

This section describes how to request a check transaction status. This transaction is used to obtain response data for a transaction that was lost or timed out. You can request a check transaction status when you have the
transactionIdentifier
 value for the transaction that you want to query. The transaction details are shown on the Summary screen.
Follow these steps to request a check transaction status:
  1. Obtain 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. You can get the full transaction object by retrieving the
    latestTransaction
     from the mposUi object.
    
 
    val transactionObject = mposUi.latestTransaction
