To support transaction notifications, process TNS notifications (transactions) as described in Handle push notifications.

Get transactions

TransactionHistoryService retrieves both transaction history and transaction notification details from the NFC Wallet backend.

The transaction record contains the following information:

• Transaction ID
• Transaction date
• Transaction type
• Transaction status
• Currency code
• Amount and display amount
• Merchant name
• Merchant type
• Merchant postal code
• Terminal ID
• Merchant ID
• Primary or auxiliary card indicator (for co-badged cards)

Transaction history limits depend on the payment network:

• Time window (for example, transactions from the last 30 days).
• Maximum count (for example, the last 10 transactions).

The following code snippet demonstrates how to retrieve the transaction records:

func transactionHistory() async {
    do {
        let historyService = TransactionHistoryService()
        let records = try await historyService.records(forDigitalCardID: "DIGITAL_CARD_ID")

        for record in records {
            // Display record fields in your UI.
            _ = record.id
            _ = record.date
            _ = record.status
            _ = record.type
            _ = record.currencyCode
            _ = record.amount
            _ = record.displayAmount
            _ = record.merchantName
            _ = record.merchantType
            _ = record.merchantPostalCode
            _ = record.terminalID
            _ = record.merchantID
            _ = record.isAuxiliaryTransaction
        }
    } catch {
        if let error = error as? TransactionHistoryService.Error {
            // Handle the error.
        }
    }
}

For co-badged cards, isAuxiliaryTransaction indicates whether the record belongs to the auxiliary card.
