# Events

An **event** is a notification payload generated through user actions, system signals, and ledger updates.

Events are the notification payloads generated through user actions, system signals, and ledger updates.

Event payloads follow a common pattern including the following fields:
- `id`, a unique identifier for the event,
- `domainId`, a reference to the domain where the event has been issued,
- `sequenceNumber`, a strictly increasing sequence number (but possibly non contiguous),
- `savedAt`, a timestamp, and
- `payload`, additional information depending on the event type.
