Back-end Operations

Important Information
As of 30 September 2020, our even faster, more convenient checkout solutions will replace the solutions this documentation was primarily built for. We will no longer offer support for the following solutions: Checkout Page, Checkout Seamless, Checkout Enterprise, Toolkit, Checkout Terminal & Payment Center.

For this reason, you must switch to our updated solutions in order to continue processing online transactions compliant with the latest PSD2 and 3D Secure 2 requirements.

Please take a look at our new online documentation, or learn more about your benefit from an improved checkout experience for you and your customers.


Back-end operations both for Wirecard Checkout Page (also referred to as Toolkit light) and Wirecard Checkout Seamless allow you to use commands which enable various operations regarding the orders of your consumers or the payment process itself. These operations are called by a server-to-server request from your web server to the Wirecard Checkout Server. So you have the possibility either to call these operations automatically from the back-end of your online shop or manually from your user interface you have implemented for administration purposes in your online shop.

Back-end operations for Wirecard Checkout Page and Wirecard Checkout Seamless are subdivided into two categories:

  • Transaction-based operations
  • Non-transaction-based operations

Transaction-based operations
Transaction-based operations for Wirecard Checkout Page and Wirecard Checkout Seamless depend on existing orders, i.e. orders which have been completed by the consumers in your online shop and which are at your disposal for further actions.

Non-transaction-based operations
Non-transaction-based operations for Wirecard Checkout Page and Wirecard Checkout Seamless do not depend on existing orders. I.e. such operations are carried out independently of any existing orders.
