Airwallex cancel_url is silently ignored: use back_url or failUrl

TL;DR

Pass backurl for Billing Checkout, or failUrl and successUrl for the Hosted Payment Page. When your Airwallex checkout never returns the shopper to the right place on cancel, check the parameter name: cancelurl is not a real Airwallex parameter and gets ignored without an error.

Why this happens

The original report does not dig into a root cause. It documents the symptom and the fix that resolved it.

Source: Airwallex's official billing checkout skill reference: no Airwallex API accepts a cancelurl parameter, so it is silently ignored. Billing Checkout expects backurl; the Hosted Payment Page expects failUrl and successUrl. The same troubleshooting table notes that checkout URLs expire after one hour and must be recreated, and that webhook signature failures are usually fixed by reading the raw body (express.raw) before parsing.
