# Events

> Internally, Rasa conversations are represented as

Internally, Rasa conversations are represented as
a list of [events](/docs/reference/integrations/action-server/events). Rasa SDK provides classes
for each event, and takes care of turning instances of event classes into properly formatted
event payloads.

This page is about the event classes in `rasa_sdk`.
The side effects of events and their underlying
payloads are identical regardless of whether you use `rasa_sdk` or another action
server.
For details about the side effects of an event, its underlying
payload and the class in Rasa it is translated to
see the [documentation for events for all action servers](/docs/reference/integrations/action-server/events)
(also linked to in each section).

<Tip>
  **Importing events**

  All events written in a Rasa SDK action server need to be imported from `rasa_sdk.events`.

)
```

**Underlying event**: [`slot`](/docs/reference/integrations/action-server/events#slot)

**Parameters**:

* `key`: Name of the slot to set
* `value`: Value to set the slot to. The datatype must match the [type](/docs/reference/primitives/slots#slot-types)
  of the slot
* `timestamp`: Optional timestamp of the event

**Example**

```python theme={null}
evt = SlotSet(key = "name", value = "Mary")

**Example**:

```python theme={null}
evt = AllSlotsReset()
```

### ReminderScheduled

```python theme={null}
rasa_sdk.events.ReminderScheduled(

**Example**:

```python theme={null}
from datetime import datetime

evt = ReminderScheduled(
    intent_name = "EXTERNAL_dry_plant",
    trigger_date_time = datetime(2020, 9, 15, 0, 36, 0, 851609),
    entities = [{"name": "plant","value":"orchid"}],
    name = "remind_water_plants",
