Description
The KORONA.pos Client API is intended to extend the functionality of the POS. It allows external applications to interact with the cashier and even modify the current transaction. Common applications are:
- CRM Systems
- Loyalty System
- Order Management Systems
- Payment System
All External applications are contacted via HTTP call. A system call can be configured for as POST or GET to transfer current transaction data to the external system. If a system requires presenting a UI to the cashier the response has to be a valid HTML page.
The POS can be configured for external system calls using the following triggers:
- Button
- On Total (before payment)
- After Receipt Booking
- On Receipt Void
- On Receipt Rejection
Setup
1) Configure External System Call
Configure your external system call in the back office under Settings > External System Calls
Display URL are being displayed at the POS and require an HTML response. The System URL is called in the background and will always submit data via POST. Display applications can receive data via POST or via JavaScript and can submit their response via JavaScript whereas System URL applications need to submit responses as JSON. Depending on whether the external system requires UI you configure either a system URL or a display URL. All other parameters are optional.
2) Setup Button or Trigger
Assign the external system call to a button or trigger in the POS profile.
3) Update POS
Retrieve Master Data at the POS and restart the POS.
