# Notification Rules

> Set up conditional event alerts with Python

## List rules

```python theme={null}
rules = app_res.notification_rules.list()
```

## Create a rule

```python theme={null}
rule = app_res.notification_rules.create({
    "name": "Alert on large payment failure",
    "event_name": "payment.failed",
    "enabled": True,
    "conditions": [
        {
            "id": "cond-1",
            "field": "amountCents",
            "operator": "greater_than",
            "value": 10000,
        },
    ],
    "actions": [
        {
            "id": "action-1",
            "destination_id": "dest-uuid-here",
            "channel": "slack",
            "enabled": True,
        },
    ],
})
```

<Tip>
  Pass an empty `conditions` list to trigger on every matching event.
