| Option | Description | Multiple payment methods | Single payment method |
|---|---|---|---|
| UI integration - Hosted Payment Page (HPP) | Launch a complete, SDK-managed payment flow with prebuilt screens for payment method selection, card input, and checkout. Supports customizable theming and dark mode. Recommended for most use cases. |  |  |
| UI integration - Embedded Element | Embed Airwallex's AWXPaymentElement directly into your own view hierarchy using UIKit. You retain full control over the host layout and navigation while leveraging the SDK's payment UI components. |  |  |
| Low-level API integration | Build a fully custom payment UI using the SDK's core APIs. Gives you direct access to payment method retrieval, card tokenization, payment confirmation, and consent management. Your app must be PCI-DSS compliant if using Low Level API Integration for payment with card and billing details flow. Provide a PCI-DSS AOC and renew it regularly. |  |  |
