# 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.
