Integration Options

There are multiple integration options available for Wirecard Payment Gateway.

  • The integration via Payment Page is described under Payment Page.

  • For (near) real-time processing the backend implementation is described under REST API. However, the description of payment methods, for example, is common for both Payment Page and REST API.

  • Processing of multiple transactions using batches is described under Batch Processing API, available for both SEPA Direct Debit and SEPA Credit Transfer.

  • Our Payment SDK offers a seamless user experience by rendering a payment form as an integral part of the merchant’s mobile application.

Payment Page

Wirecard Payment Page stands for secure, flexible, easy and transparent payment processing.

It provides all payment methods and related options in one solution: Credit Card (with/without 3D secure), SEPA, online banking payments, mobile payments, alternative payment methods, and industry-specific solutions.

It handles the payment method selection as well as the collection of payment details or consumer redirects to alternative payment provider sites. With this solution, the merchant is only required to conform to a limited PCI scope (self-questionnaire A).

Wirecard Payment Page is available in three formats:

  • Hosted Payment Page (HPP): The consumer is redirected to Wirecard Payment Gateway to finish the checkout process.

  • Embedded Payment Page (EPP): The payment screen is displayed in overlay directly on the merchant’s checkout page.

  • Seamless integration: The merchant’s checkout page is incorporated into Wirecard’s payment form. This solution provides a seamless shopping experience for web-shoppers.

Only HTML knowledge is required for Wirecard Payment Page integration.

REST API

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)

  • JSON respectively

  • 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.

Batch Processing API

In order to process multiple transactions at the same time, Wirecard’s Batch Processing is the ideal solution for both fast and easy to implement offline bulk transaction processing.

Batch processing is possible for the following payment methods:

  • SEPA Direct Debit

  • SEPA Credit Transfer

  • Credit Card

Working programming knowledge is required to integrate this way.

SDK

The Software Development Kit (SDK) serves as a wrapper for the Wirecard Payment Gateway with a PCI V3 compliant native mobile payment form. SDK is naturally developed for the integration into a merchant’s app as a software library where it covers sending payment requests to the Wirecard Payment Gateway. It uses REST requests constructed by the merchant sent over HTTPS protocol to Wirecard Payment Gateway end-point where the REST API is exposed.

The following payment methods are currently supported:

  • Credit Card

  • PayPal

  • SEPA Direct Debit

  • Apple Pay

  • Google Pay™

Operation system interfaces:

  • iOS

  • Android

Working programmer knowledge is required to integrate this way.
