Very much a work-in-progress that will receive attention only as required by my own personal automation-flow.

Description

Great Southern Bank (Formerly CUA) unfortunately does not provide an api for accessing and managing your bank account automatically.

This is a simple api using Playwright to control GSB's online banking website for such reasons.

Example

fun main() {
    // HeadFULL for development
    GSBPlaywrightOnlineBanking { setHeadless(false) }.use { bank ->
        main(bank)
    }
}

private fun main(bank: GreatSouthernBank) {
    val credentials = readCredentials()
    val gsb = bank.login(credentials).unwrap()

    val accounts = gsb.accounts().unwrap()
    printAccounts(accounts)

    val account = accounts.first()
    val transactions = gsb.transactions(account).unwrap()
    printTransactions(account, transactions)

    val payees = gsb.payees().unwrap()
    printPayees(payees)
}

Output using picnic for table generation:
