# GA4: Event Taxonomy Validation A generic taxonomy validator. The built-in required-parameter table covers Google's recommended e-commerce events as one example; for other event schemas (lead-gen, content, SaaS engagement, custom), supply your own table via `--required-params`. ## Process 1. Verify auth. 2. Spawn the `ga4-events` agent. 3. Default window: 7 days (event-shape sampling, not trend analysis). ## Built-in checks | Check | What it does | |-------|---------------| | Presence | Does the event fire at all in the window? | | Required parameters | What share of events carry each required parameter? | | Identifier uniqueness | For events with an ID (e.g. `purchase.transaction_id`), is it unique? | | Volume sanity | Outlier days where event volume drops or spikes sharply | | Post-payment heuristic (opt-in) | `add_payment_info` count within 10% of `purchase` count → fires after the payment gateway redirect-back | ## After analysis Offer: "Want to see the funnel with validated steps? Use `/ga4 funnel <property-id>`"
