# Alert properties

## List of properties

All alerts send the same list of properties across all alert types, they relate to both:

* The alert that you set on Sonar
* The event that triggered your alert

Below are the properties passed in the json:

| key            | type        | options      |
| -------------- | ----------- | ------------ |
| event\_id      | int         | Open         |
| timestamp      | timestamptz | Open         |
| type           | string      | Limited to 4 |
| alert\_name    | string      | Open         |
| event\_verbose | string      | Open         |
| domain         | string      | Open         |

{% hint style="info" %}
The *event\_verbose* has been added to allow further flexibility on the way you use the alert.
{% endhint %}

As opposed to event properties or company properties, alert properties are not sent in a nested json but rather sent directly in the first level of the json object as shown below:

```javascript
{
  "event_id": 458325, // Not nested
  "timestamp": "2020-04-23T12:25:32.209Z", // Not nested
  "type": "technology_removed", // Not nested
  "alert_name": "Hotjar deleted", // Not nested
  "event_verbose": "Wine Central removed Hotjar", // Not nested
  "domain": "winecentral.co.nz", // Not nested
  "event_properties": {
    "technology_name": "Hotjar",
    "technology_domain": "https://www.hotjar.com/",
    "technology_category": "Analytics"
  },
  "company_properties": {
    "company_name": "Wine Central",
    "alexa_rank": null,
    "country": "New Zealand",
    "location": "Albany, Auckland, New Zealand",

  }
}
```
