Marketing pixel not firing

Confirm the Pixel ID is correct in Marketing → Integrations (or Meta → Connection) with no extra spaces.

For Meta: use Connect with Meta so Pixel + Conversions API are both active. Check Marketing → Meta → Diagnostics for failed or skipped server events.

Disable ad blockers when testing. Use Meta Events Manager → Test events with Test mode enabled under Meta → Advanced.

Events fire on the live storefront — preview mode in the builder may not trigger pixels. Purchase dedupes with purchase_{orderNumber} across Pixel and CAPI.

Allow up to 24 hours for ad platforms to show aggregate data after first install.
