Event handler is a new feature in Oracle Digital Assistant 21.02 and later that provides an event driven mechanism to execute custom logic in the context of resolving a composite bag entity. The custom logic you implement may include custom validations, customized prompts and disambiguation messages, or access to remote REST services for querying and updating data.
Very soon we will publish two new tutorials about entity event handlers on our product documentation page. Until then, this article will get you started. What you will learn following the instructions in this article is how to create an event handler and how to use the custom component SDK to render prompts as card layouts.
You will also notice how using event handlers, you can add advanced functionality to the ResolveEntities component.
