# 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.
