GA4 Event Name Checker for Current Web Rules

GA4 event name checker

Event-name assessmentComplete the fields and calculate.

How it works

Checks the 40-character collection limit and letter-first format.
Allows case-sensitive English and non-English letters, numbers, and underscores.
Checks the query_id web prefix and the current reserved web event-name list.
Does not claim that a syntactically valid name is the right semantic event.

Before you act

Google says its reserved-name list is not exhaustive and can change; the page links to the current official rule source for final verification.
Do not place personal data or user-generated text in an event name or parameter.

Privacy

Calculations run in the browser. The form values are not posted to slicky.click, stored in an account, or added to the page URL.

Primary source
