Embedded Checkout Page API Document

Creating Order / Introduction

Scenario

After receiving the token, merchants should set this token onto merchant’s webpage with the integration of ECPay’s JavaScript SDK to access the checkout page. ECPay will then validate this token to check merchant’s identity before displaying the checkout page.
