Generic confirmation pages

When creating an HPP Session you can define the URL that you want the Consumer to be redirected to after making an action on the payment page. These URLs are in the merchant_urls block, but they are also optional. When you don’t put any value in there, generic pages are displayed to the Consumer.

Parameters

A description of the options that can be passed to HPP. All of these are optional, some default to a sensible value if omitted in the call.

Logo and Feature image

When provided your logo and feature image will appear on the Hosted Payment Page, their positions will depend on the Consumer’s browser capacities as HPP as different responsive designs. Both can be configured through the merchant portal. Merchants can try their setup in playground as well as production environment. It may take sometime for the changes to reflect on HPP.

Logo configuration is documented at Merchant Branding Configuration Page

Background Images

Use this parameter to send a list of images to use as backgrounds on the payment page. HPP will use the image that fits the better to the Consumer’s browser capacities using the width parameter given. Images have to be served over HTTPS to avoid all kind of security warning on the Consumer’s browser.
