Requesting a 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:

Access the

transactionIdentifier

value in the

onActivityResult

method of the original transaction.

Retrieve the transaction

summaryIntent

value 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 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()  
    }
}

You can get the full transaction object by retrieving the

latestTransaction

from the mposUi object.

val transactionObject = mposUi.latestTransaction
