[GA4] Custom events

Collect additional information that Google Analytics does not collect automatically

A custom event is an event whose name and parameters you define. A custom event lets you collect data that Analytics doesn't otherwise collect automatically or recommend. 

Custom Events in Google Analytics

Before you create a custom event:

Set up a custom event

Set up your custom event using one of the following options:

Modify a custom event

You can modify a custom event that's already being collected (for example, to rename the event or correct an error). This way, you can keep the data you already collected from an existing event.

Report on a custom event

When someone performs the action that triggers the custom event, the event will appear in the Realtime report and DebugView. You can also click the name of an event in the Realtime report and DebugView to see its event parameters.

When Analytics processes your custom event, you can use the following to see the event:

  • In Reports, go to the Events report
  • In Admin, go to Events in the Property column
  • In Explore, create a free-form exploration with the Event name dimension

Report on a custom event parameter

To see the event parameter values, you must create a custom dimension or metric for each event parameter. Once Analytics processes the custom dimension or metric, you can add it to your custom reports, audiences, explorations, and segments, and as secondary dimensions in standard reports.
