# 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](https://legacy-docs-v1.rasa.com/1.10.9/api/events/#id2)

### [Set a Slot](https://legacy-docs-v1.rasa.com/1.10.9/api/events/#id3)
Short
Event to set a slot on a tracker

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`.
Every slot has a name and a value. This event can be used to set a value for a slot on a conversation.

### [Restart a conversation](https://legacy-docs-v1.rasa.com/1.10.9/api/events/#id4)
Short
Resets anything logged on the tracker.

JSON

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

Class `rasa.core.events.Restarted`(_timestamp=None_, _metadata=None_)  
Conversation should start over & history wiped.
Instead of deleting all events, this event can be used to reset the tracker state (e.g. ignoring any past user messages & resetting all the slots).

### [Reset all Slots](https://legacy-docs-v1.rasa.com/1.10.9/api/events/#id5)
Short
Resets all the slots of a conversation.

JSON

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

Class `rasa.core.events.AllSlotsReset`(_timestamp=None_, _metadata=None_)  
All Slots are reset to their initial values.
If you want to keep the dialogue history and only want to reset the slots, you can use this event to set all the slots to their initial values.

### [Schedule a reminder](https://legacy-docs-v1.rasa.com/1.10.9/api/events/#id6)
Short
Schedule an intent to be triggered in the future.

JSON

```
evt = {
  "event": "reminder",
  "intent": "my_intent",
  "entities": {"entity1": "value1", "entity2": "value2"},
  "date_time": "2018-09-03T11:41:10.128172",
  "name": "my_reminder",
  "kill_on_user_msg": True,
}
```

### [Cancel a reminder](https://legacy-docs-v1.rasa.com/1.10.9/api/events/#id7)
Short
Cancel one or more reminders.

JSON

```
evt = {
  "event": "cancel_reminder",
  "name": "my_reminder",
  "intent": "my_intent",
  "entities": [
        {"entity": "entity1", "value": "value1"},
        {"entity": "entity2", "value": "value2"},
    ],
  "date_time": "2018-09-03T11:41:10.128172",
}
```

### [Pause a conversation](https://legacy-docs-v1.rasa.com/1.10.9/api/events/#id8)
Short
Stops the bot from responding to messages. Action prediction will be halted until resumed.

```
evt = {"event": "pause"}
```

### [Resume a conversation](https://legacy-docs-v1.rasa.com/1.10.9/api/events/#id9)
Short
Resumes a previously paused conversation. The bot will start predicting actions again.

JSON

```
evt = {"event": "resume"}
```

### [Force a followup action](https://legacy-docs-v1.rasa.com/1.10.9/api/events/#id10)
Short
Instead of predicting the next action, force the next action to be a fixed one.

JSON

```
evt = {"event": "followup", "name": "my_action"}
```

## [Automatically tracked events](https://legacy-docs-v1.rasa.com/1.10.9/api/events/#id11)

    "parse_data": {
        "intent": {
            "name": "greet",
            "confidence": 0.9
        },
        "entities": []
    },
    "metadata": {},

```

### [Undo a user message](https://legacy-docs-v1.rasa.com/1.10.9/api/events/#id14)

```

### [Undo an action](https://legacy-docs-v1.rasa.com/1.10.9/api/events/#id15)

```

### [Start a new conversation session](https://legacy-docs-v1.rasa.com/1.10.9/api/events/#id17)
Short
Marks the beginning of a new conversation session. Resets the tracker and triggers an `ActionSessionStart` which by default applies the existing `SlotSet` events to the new session.

JSON

```
evt = {"event": "session_started"}
```
