# Use GA4 realtime to verify events now

> Tier: recipe. Operating recipe: real tool sequence, core rules, known traps.

The realtime read for verification moments: launches, tag fixes, incident checks.

**Intent.** Whether an event fires right now, during a launch or a fix.

## When to use

- Launch minutes.
- Right after a tagging fix ships.

## When not to use

- Performance conclusions: realtime is presence, not measurement.

## Sources

Required: Google Analytics 4

## Preconditions

- The account is ticked in the dashboard, confirmed via list_accounts.

## Inputs

- `window`: Analysis window. Default: last 30 days.

## Procedure

1. Run the realtime report filtered to the event. — tools: `ga4_run_realtime_report`
2. Confirm presence and rough magnitude, then hand back to windowed reads.

## Decision rules

- **When** The event appears in realtime after the fix → **conclude** Presence confirmed only: volume and correctness still need the windowed read tomorrow.

## Evidence requirements

- Every figure carries its account, metric and window.
- Anything below a readable sample size is reported as unjudged, not as zero.

## Human approval boundary

- The readout changes nothing. Any change it motivates goes through Safe Writes: preview, human confirmation, then apply.

## Failure modes

- Realtime samples and trims: absence over a minute proves little on low-traffic sites.

## Output

- **Readout**: The figures, with windows and accounts named.
- **Flags**: What deserves a deeper skill or a human decision.
