Event Reference (v1) / Form Events

Form Submit form_submit

Measures when a user successfully completes/submits a form.

This event is generic by design in order to have aggregate data on all forms (regardless of their purpose). It is common to use synthetic events (in addition to form_submit) that are for conversion purposes that measure a specific cohort of total form_submit events.

For example, you may have a demo_request event that measures ONLY forms used for demo requests. Using synthetic events is recommended to give you a more concrete view of how users are entering your funnel.

This event should ONLY be sent if the form data passed validation, and before any redirect occurs. We suggest using native form submission lifecycle hooks/APIs supplied by the form provider to ensure this event fires at the correct time.

GA4 implements this event as part of its "Enhanced Measurement" feature. It is generally recommended to use Google Tag Manager to manage event flow and data collection. As such, we recommend disabling this event inside your Enhanced Measurement settings.
