## TL;DR

Pass back_url 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: cancel_url is not a real Airwallex parameter and gets ignored without an error.

## Steps

1. When your Airwallex checkout never returns the shopper to the right place on cancel, check the parameter name: cancel_url is not a real Airwallex parameter and gets ignored without an error. Pass back_url for Billing Checkout, or failUrl and successUrl for the Hosted Payment Page. And regenerate checkout links older than an hour; they expire silently.

## When to use

You are seeing this: When your Airwallex checkout never returns the shopper to the right place on cancel, check the parameter name: cancel_url is not a real Airwallex parameter and gets ignored without an error. Use this skill when you run into "Airwallex cancel_url is silently ignored: use back_url or failUrl".

## When not to use

## Versions

## Why this happens

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