When merchants want full control over the checkout and payment process they can create requests themselves and send them directly to the REST API. All communications between a merchant and the REST API are secured by TLS encryption (HTTPS).
Integration is possible by:
XML requests sent from merchant’s backend (server-to-server)
NVP (for credit card only)
|For the integration of Wirecard Payment Gateway via REST API, advanced programming skills are required.|
PCI certified merchants can use Wirecard Payment Gateway without any restrictions.
Non PCI certified merchants can use Wirecard Payment Gateway only with referenced or recurring transactions. For initial transactions they must use a front end solution (e.g. HPP).
Details to integrate Wirecard Payment Gateway via REST API are described here.
