What are Oliver Apps?
Oliver Apps are custom building blocks that are implemented by developers to extend the POS experience with Oliver. By interfacing with products, customers or sales data, you can create the most adaptable workflow possible.
An app can communicate with OliverPOS by talking to a parent window. These are done using App Commands, which can be used to send POST, GET, PUT, or DELETE messages to Oliver.
An app can also request to hook into callback events so that they get notified whenever the event they hooked into has been triggered. The callback events are called App Events.
