# System Events

> System webhook events for Dynamic Rules changes

System Events notify your server about OFAuth system-level changes that affect integrations, currently focused on Dynamic Rules updates.

## Event Types

| Event           | Trigger                                    |
| --------------- | ------------------------------------------ |
| `rules.updated` | Dynamic Rules signing requirements changed |

## When To Use

Subscribe to System Events if you make direct OnlyFans API requests and need to react when signing requirements change.

<Tip>
  Most integrations do not need `rules.updated`. If you use the [Access API](/api-reference/access/overview), OFAuth handles request signing for you.
</Tip>

## Handling `rules.updated`

When you receive `rules.updated`:

1. Refresh any cached signing rules.
2. Re-sign subsequent direct OnlyFans API requests with the latest revision.
3. Avoid polling for new rules unless your workflow explicitly requires it.
