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:
