## Overview

When your app uses [Shopify Checkout Sheet Kit](https://github.com/Shopify/checkout-sheet-kit-ios) for checkout, Forter needs the **checkout token** to correlate fraud signals with the transaction.

The SDK exposes the token at two points:

- `checkoutDidEmitWebPixelEvent` — fires when the checkout opens (`checkout_started`), providing the token before payment
- `checkoutDidComplete` — fires after successful payment, providing the token and order ID

## Integration

```swift
ShopifyCheckoutSheetKit.present(checkout: checkoutURL, from: self, delegate: self)
```

```swift
extension CheckoutViewController: ShopifyCheckoutSheetKitDelegate {

    func checkoutDidEmitWebPixelEvent(event: PixelEvent) {
        guard case .standardEvent(let standardEvent) = event,
              standardEvent.name == "checkout_started",
              let checkoutToken = standardEvent.data?.checkout?.token else { return }

        ForterSDK.sharedInstance().trackAction(.paymentInfo, withData: [
            "checkoutToken": checkoutToken
        ])
    }

    func checkoutDidComplete(event: CheckoutCompletedEvent) {
        let checkoutToken = event.orderDetails.cart.token
        let orderId = event.orderDetails.id

        ForterSDK.sharedInstance().trackAction(.paymentInfo, withData: [
            "checkoutToken": checkoutToken,
            "orderId": orderId
        ])
    }
}
```
