Validate the Meta event parameters your browser exposes

Check browser-visible Meta events for purchase value, currency and event-ID structure without sending data to Meta.

Public event page

Inspect public Meta browser events for event name, value, currency and event-ID parameter shape. Server-side events are reported as an explicit limitation.

This tool answers: Are the Meta event parameters visible in this browser request structurally complete?

Enable JavaScript to run the check — the diagnosis itself is free and needs no account.

Why this happens

A Purchase event with no value or currency can make ROAS unreliable even when Meta counts it.

Missing event IDs also make browser and server deduplication difficult to prove.

How this check works

So you can trust the result — and your developer can verify it.

  1. Classify Meta events

    We distinguish purchase-like events from ordinary page activity.

  2. Check structural fields

    Value, ISO currency and event-ID presence are validated from the browser request.

Common causes and fixes

Checkout data is unavailable
A tag fired before the final order total was ready.
No shared event ID
Pixel and CAPI need one stable key when both report a conversion.

Frequently asked questions

Does it validate CAPI payloads?
It validates only browser-visible fields and explains the CAPI limit.
Is zero a valid value?
A free order can be zero; the check focuses on missing or malformed structure.

Make every Meta conversion structurally useful.
