Step 3: Use WebViewPaymentViewController Directly

If you need more control over presentation, use WebViewPaymentViewController directly instead of WePaySDK.openCheckoutUrl().

---

Presenting the View Controller

import WePaySDK

let webVC = WebViewPaymentViewController(checkoutUrl: checkoutUrl)
let nav = UINavigationController(rootViewController: webVC)
nav.modalPresentationStyle = .fullScreen
present(nav, animated: true)

---

When to Use This Approach

Scenario	Recommended Approach
Simple integration, default behavior	WePaySDK.openCheckoutUrl()
Custom navigation controller configuration	WebViewPaymentViewController directly
Custom presentation style (e.g., sheet, formSheet)	WebViewPaymentViewController directly
Need to set a delegate or observe dismissal	WebViewPaymentViewController directly
Embedding in a container view controller	WebViewPaymentViewController directly

---

Handling Dismissal

You can use presentationController(_:didDismiss:) or a custom delegate on the view controller to detect when the user dismisses the checkout:

import WePaySDK

class ViewController: UIViewController {

    func openWePayCheckout(checkoutUrl: String) {
        let webVC = WebViewPaymentViewController(checkoutUrl: checkoutUrl)
        let nav = UINavigationController(rootViewController: webVC)
        nav.modalPresentationStyle = .fullScreen
        nav.presentationController?.delegate = self
        present(nav, animated: true)
    }
}

extension ViewController: UIAdaptivePresentationControllerDelegate {
    func presentationControllerDidDismiss(_ presentationController: UIPresentationController) {
        // Checkout was dismissed — refresh order status
    }
}
