  • Payment page integration

The Payment Page integration is only supported if a payment method selection screen is displayed. So either do not send the paymentmethod parameter at all (and have multiple payment methods active) or at minimum specify payment method Google Pay. For example: paymentmethod=PAY

Description

Google Pay is a payment platform that can be used across devices with a Google-Account. It enables merchants to offer a better and faster checkout experience for their clients. Google Pay supports NFC (card present), in-app purchases for card not present and browser based shop solutions (Google Pay Web).Datatrans supports Google Pay on the web and through our XML-APIs.

Checkout our Github-sample to find out more on implementation details and testing.
