Online Basket Service​

Online - Add Item to Enactor Basket Service

At first glance, adding an item to a basket seems simple... but in reality the process must:

  • Determine if a basket exists and check the basket state / create it if not
  • Check that the item is of a known type and what other items might be affected by this item
  • Calculate any discounts or other modifiers that might trigger
  • Call the Promotions Engine and apply any promotion savings that might now be triggered
  • Check to see if any vouchers have been triggered
  • Apply rules if this is an employee
  • Calculate tax...

This involves approximately 30 sub-processes and 100+ business logic nano-components, all built using the low-code toolkit.

Built once with the visual designer — the same business logic serves all integration patterns
Integrate with any external system regardless of its preferred API technology

A single call can be routed through any of five different technologies to reach the same underlying process flow:

  • REST API
  • Kafka Message
  • Framework Invocation
  • GRPC
  • RMI

The platform can integrate with any external system regardless of its preferred API technology, and the same business logic serves all integration patterns.
