# 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

Short: Event to set a slot on a tracker

JSON

```json
evt = {"event": "slot", "name": "departure_airport", "value": "BER"}
```

Class `rasa.core.events.SlotSet`( _key_, _value=None_, _timestamp=None_, _metadata=None_)

The user has specified their preference for the value of a `slot`.

### Restart a conversation

Short: Resets anything logged on the tracker.

JSON

```json
evt = {"event": "restart"}
```

Class `rasa.core.events.Restarted`( _timestamp=None_, _metadata=None_)

### Reset all Slots

Short: Resets all the slots of a conversation.

JSON

```json
evt = {"event": "reset_slots"}
```
