[GA4] Custom events

Measure additional information that's important to your business

A custom event is an event with a name and set of parameters that you define so you can collect information that's specific to your business. For example, you could create a donate custom event for when someone donates to an organization.

Before you create a custom event, review the list of automatically collected, enhanced measurement, and recommended events. These types of events automatically populate prebuilt dimensions and metrics and don't impact the limits on the number of events and parameters you can create.

Set up custom events

You can set up a custom event in a few different ways, depending on whether you are setting up a custom event for a website or app.

  • To set up a custom event for a website, see Set up events.
  • To set up a custom event for a mobile app, see Log events.

See custom events in Analytics

To see your custom events in Google Analytics, you need to create custom dimensions and metrics for the custom events and parameters.
