Introduction

This guide is written for application developers who want to integrate AlipayHK In-App Online Payment solution and AlipayHK Auto-Debit Payment solution.

The AlipayHK In-App Online Payment is used for in-app payment and the Auto-Debit service can be used by merchants to auto-debit transactions after users authorized the payment agreement successfully, without the payment password being entered by users each time after authorization.
