# Get transaction history

## Overview

With the transaction history  you digital wallet application can support:

* Transaction notifications
* Transaction history refresh

{% hint style="warning" %}
During onboarding, confirm that transaction history is enabled for your program.
{% endhint %}

## SDK Integration

### Transaction notification

To support transaction notifications, process **TNS notifications (transactions)** as described in [Handle push notifications](/nfc-wallet-sdk-ios/get-started/configuration/4.-push-notifications/handle-push-notifications.md#process-tns-notifications-transactions).

### 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:

```swift
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.
