Common GTM and Meta CAPI Mistakes: A QA Checklist

In brief: Common GTM and Meta CAPI Mistakes: A QA Checklist — the practical answer

Common tracking errors include counting clicks as successful leads, generating separate browser/server IDs and sending repeated purchase events. A small test plan catches these before reporting becomes misleading.

What to do first

Test invalid forms, successful submissions, reloads and repeated callbacks.

Implementation and review

  1. Verify event names, identifiers, values, currency and consent behavior across destinations.
  2. Inspect browser and server diagnostics and compare against a known test order or lead.

What to watch for

A dashboard receiving events is not proof of accuracy. Validate the business outcome and retry behavior.

A practical example to work through

Follow a single test order from the application to each destination, including a repeated callback. Check that the order ID, value and currency remain consistent and that a retry does not become another purchase. Repeat the process for a failed order. Fixing these basic distinctions gives the team a stronger measurement foundation than adding more dashboard widgets.
