## Reference

## 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.

### General Purpose Events

- [Set a Slot](https://legacy-docs-v1.rasa.com/1.8.0/api/events/#set-a-slot)
- [Restart a conversation](https://legacy-docs-v1.rasa.com/1.8.0/api/events/#restart-a-conversation)
- [Reset all Slots](https://legacy-docs-v1.rasa.com/1.8.0/api/events/#reset-all-slots)
- [Schedule a reminder](https://legacy-docs-v1.rasa.com/1.8.0/api/events/#schedule-a-reminder)
- [Cancel a reminder](https://legacy-docs-v1.rasa.com/1.8.0/api/events/#cancel-a-reminder)
- [Pause a conversation](https://legacy-docs-v1.rasa.com/1.8.0/api/events/#pause-a-conversation)
- [Resume a conversation](https://legacy-docs-v1.rasa.com/1.8.0/api/events/#resume-a-conversation)
- [Force a followup action](https://legacy-docs-v1.rasa.com/1.8.0/api/events/#force-a-followup-action)

### Automatically tracked events

- [Bot responded message](https://legacy-docs-v1.rasa.com/1.8.0/api/events/#bot-responded-message)
- [Undo a user message](https://legacy-docs-v1.rasa.com/1.8.0/api/events/#undo-a-user-message)
- [Undo an action](https://legacy-docs-v1.rasa.com/1.8.0/api/events/#undo-an-action)
- [Log an executed action](https://legacy-docs-v1.rasa.com/1.8.0/api/events/#log-an-executed-action)
