Events

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.
