# 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"}
```

### Restart a conversation

Short

Resets anything logged on the tracker.

JSON

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

### Reset all Slots

Short

Resets all the slots of a conversation.

JSON

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

### Schedule a reminder

Short

Schedule an intent to be triggered in the future.

JSON

```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

Short

Cancel one or more reminders.

JSON

```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

Short

Stops the bot from responding to messages. Action prediction
will be halted until resumed.

JSON

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

### Resume a conversation

Short

Resumes a previously paused conversation. The bot will start
predicting actions again.

JSON

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

### Force a followup action

Short

Instead of predicting the next action, force the next action
to be a fixed one.

JSON

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

## Automatically tracked events

### User sent message

Short

Message a user sent to the bot.

JSON

```json
evt = {
    "event": "user",
    "text": "Hey",
    "parse_data": {
        "intent": {
            "name": "greet",
            "confidence": 0.9
        },
        "entities": []
    },
    "metadata": {},
}
```

### Bot responded message

Short

Message a bot sent to the user.

JSON

```json
evt = {"event": "bot", "text": "Hey there!", "data": {}}
```

### Undo a user message

Short

Undoes all side effects that happened after the last user message
(including the `user` event of the message).

JSON

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

### Undo an action

Short

Undoes all side effects that happened after the last action
(including the `action` event of the action).

JSON

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

### Log an executed action

Short

Logs an action the bot executed to the conversation. Events that
action created are logged separately.

JSON

```json
evt = {"event": "action", "name": "my_action"}
```

### Start a new conversation session

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

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