 You may do so by calling the `setUserData` method, this is typically done in your `AppServiceProvider`:

 use Esign\ConversionsApi\Facades\ConversionsApi;
-use FacebookAds\Object\ServerSide\UserData;

 ConversionsApi::setUserData(

 );

 You may now pass the user data along with your events:
 ```php
 use Esign\ConversionsApi\Facades\ConversionsApi;

 ConversionsApi::addEvent(

 Now that your Pixel through GTM is correctly initialized, it's time to send some events.
-Sadly the parameters between the Conversions API and Facebook Pixel are not identical, so they must be mapped to the [correct format](https://developers.facebook.com/docs/meta-pixel/reference).
 An easy way of doing this is by extending the `FacebookAds\Object\ServerSide\Event` class and implementing the `Esign\ConversionsApi\Contracts\MapsToDataLayer` interface on it:
 ```php
 use Esign\ConversionsApi\Contracts\MapsToDataLayer;
