# Technology alerts

## Triggers

Technology alerts are triggered on two cases, representing the two alert types you can set:

There are two types of technology alerts:

* **technology\_added**: when a new technology is detected on a company website
* **technology\_removed**: when a technology is no longer detected on a company website

On the json payload, the **`type`** property allows you to identify the type of alert that has been triggered:

```javascript
{
  "event_id": 458325,
  "timestamp": "2020-04-23T12:25:32.209Z",
  "type": "technology_removed", // <<<< This is where you can identify the alert type
  "alert_name": "Hotjar deleted", 
  "event_verbose": "Wine Central removed Hotjar",
  "domain": "winecentral.co.nz",
  
  ...
```

## Default properties

Both technology\_added and technology\_removed alert types send the same 3 event properties under the "event\_properties" key:

| key                  | type   | options                                                                                  |
