If you are integrating using the Card Element or Split Card Element, please note that Airwallex does not provide a dedicated form for collecting billing information.
If you have collected billing details—such as billing name, email, or address—on your own and need to pass them to Airwallex, you can include this information within the payment_method field on the frontend when using the Card or Card Number Element.
For detailed instructions and examples, please refer to our official documentation:
