Events

Conversations in Rasa are represented as a sequence of events. This page lists the event types defined in Rasa Core.

Note: If you are using the Rasa SDK to write custom actions in python, you need to import the events from rasa_sdk.events, not from rasa.core.events. If you are writing actions in another language, your events should be formatted like the JSON objects on this page.
