Korean Hosted Payment Page: The End-to-End Process

Below are screenshot examples of the checkout page process and how it works:

Step 1: Payment Method Creation
After a user has entered all the required customer details, they will be taken to the Ezypay Korean Hosted Payment Page (KHPP), where they will be presented with the 'Payment method creation' page.

It is mandatory to enter the card holder's name, and to tick the check box to agree to Ezypay's Terms and Conditions, before the user can proceed to the next step in the KHPP process.

NOTE: The required parameters are: merchant, successUrl, cancelUrl

Once the mandatory details are filled in, the user will be able to click on the "Click" button to proceed to the next step in the process. However if a user would like to cancel the creation of a payment method they can click on the button "Back to seller's page" and this will redirect them back to the URL provided by the cancelUrl parameter.
