Back-end operations both for QPAY Checkout Page (also referred to as Toolkit light) and QMORE 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 QENTA 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 QPAY Checkout Page and QMORE Checkout Seamless are subdivided into two categories:
Transaction-based operations for QPAY Checkout Page and QMORE 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 for QPAY Checkout Page and QMORE Checkout Seamless do not depend on existing orders. I.e. such operations are carried out independently of any existing orders.
