6. Set up your event mappings by following the steps in the Destinations Actions documentation on[Customizing mappings](/docs/connections/destinations/actions/#customizing-mappings).

After you've set up at least one event in your**Mappings** tab, you can see your events and parameters using the Google[Realtime](https://support.google.com/analytics/answer/9271392){:target="_blank"} and[DebugView](https://support.google.com/analytics/answer/7201382){:target="_blank"} reports. These two reports show you the events users trigger on your website as they occur. The DebugView report requires additional configuration before you can use it.

Some parameters automatically populate prebuilt[dimensions and metrics](https://support.google.com/analytics/answer/9143382){:target="_blank"} in Google Analytics. For example, the parameters on the automatically collected and enhanced measurement events and the required and optional parameters you send with the recommended events both populate pre-built dimensions and metrics.

With custom parameters, you must create[custom dimensions and metrics](https://support.google.com/analytics/answer/10075209){:target="_blank"} so you can see the parameter values in Google Analytics.

Parameters provide additional information about the ways users interact with your website. For example, when someone views a product you sell, you can include parameters that describe the product they viewed, like`product_name`,`category`, and`price`.

The automatically collected and enhanced measurement events include parameters by default. Google also provides a set of required and optional parameters to include with each recommended event. Additionally, you can add more event parameters when you need them.
