Adyen is a payment service provider headquartered in the Netherlands. It handles online payments, point of sale terminals and marketplace payments on one platform, and it publishes its own integrations for a wide range of content management systems and programming languages.
Large European businesses such as Spotify, Zalando and eBay are among its customers, which makes Adyen a credible European alternative for companies that would otherwise route card processing through a US provider. It fits merchants selling both online and in physical locations.
