Performing a Check Transaction Status

This section describes how to perform a check transaction status request. This transaction is an inquiry request that is used to obtain response data for a transaction that was lost or timed out. You can perform a check transaction status if 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 perform a check transaction status transaction:

Access the

transactionIdentifier

value in the

onActivityResult

of the original transaction.

Retrieve the transaction

summaryIntent

from the

mposUi

object.

Use the

startActivity

method to initiate the Summary screen.

val summaryIntent = mposUi.createTransactionSummaryIntent(transactionIdentifier = "transactionIdentifier")
startActivityForResult(summaryIntent, MposUi.REQUEST_CODE_SHOW_SUMMARY)

After 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_SHOW_SUMMARY) {
        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()
            }
        }
    }
}
