# Custom domains for events

{% hint style="danger" %}
This section describes how to configure the Didomi consent notice through its programmatic API and the `window.didomiConfig` object.

Most configuration options are available through the [Didomi Console](https://console.didomi.io/), and this documentation only applies to edge cases or custom implementations that require it.
{% endhint %}

In some hybrid apps (Electron, Cordova, etc.), the `location.host` value used by the Web SDK is not defined. This can cause the following issue in analytics data and events:

* Your organization has a lot of page views with no consent rate.

A custom domain can be set as part of the `didomiConfig` object to ensure that some domain is associated with API events for those applications.

You can add a `customDomain` property to the `app` object in the configuration:

```javascript
window.didomiConfig = {
  app: {
    customDomain: "custom.app.domain",
  },
};
```

{% hint style="warning" %}
Please ensure that you specify a valid domain in one of the following formats:

* A valid DNS name

  **Example:** `sandbox.domain.io`, `www.domain.io`
* A valid iOS bundle ID or Android package ID

  **Example:** `com.example.app`, `com.example.app.ios`, `com.example.app.macos`

Otherwise, it will be filtered out and not included in your analytics event data.
{% endhint %}

This configuration option is also available in the [Didomi Console](https://console.didomi.io/) as part of the Custom JSON field in the `Customization` tab.
