Apple Pay

Apple Pay integration

NOTE

We currently only support Apple Pay for the web, native iPhone app support is coming soon.

Introduction

Apple Pay can be emebedded two ways into your payment flow. In the first case, it will be displayed on Barion Smart Gateway, which needs no further development on your side, however you should request it from Customer Care through the ticketing. The second option is to display the Apple Pay button on your site ("integrated mode"), however this needs configuration and development on your side. This page will discuss the latter.
