# Multiple domain tracking

By default, the plugin will use the root level config object as the main configuration for the whole tracking system, but it is possible to include more domains to add for each event fired by simply adding an array of configurations

```javascript
import { configure } from "vue-gtag";
import router from './router'

configure({
  tagId: "GA_MEASUREMENT_ID",
  additionalAccounts: [
    { tagId: 'GA_MEASUREMENT_ID_2' },
    { 
      tagId: 'GA_MEASUREMENT_ID_3',
      config: {
        'campaign_id': 'ABCD'
      }
    }
  ]
})
```

For example, this login event will be fired for all your domains: vue-gtag will inject the `send_to` parameter for you automatically.

```javascript
import { event } from 'vue-gtag'

event('login', { method: 'Google' })
```

{% hint style="info" %}
It is possible to override the send\_to parameter at any time by just adding it to your event
{% endhint %}

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://matteo-gabriele.gitbook.io/vue-gtag/multiple-domain-tracking.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
