Why is my Facebook pixel not tracking certain events?

Topic summary

Main issue: Facebook Pixel stopped tracking certain events (e.g., Add Payment Info, Add to Cart, Search) on a Shopify site after a theme change, despite browser testing (Pixel Helper) showing correct firing. Images were attached showing no activity for these events.

Key findings and actions:

  • Theme developers fixed a duplicate Add to Cart (ATC) trigger. Issue persisted for some events.
  • A suggestion to use Facebook’s Pixel Setup Tool was declined to avoid disrupting existing campaigns.
  • Crucial fix: The site’s own domain was blocked in Facebook Event Manager. Unblocking it restored event tracking.

Technical context:

  • Facebook Pixel tracks on-site “events” like ATC (Add to Cart), InitiateCheckout, and purchases. Blocking/allowing domains in Event Manager can prevent events from being recorded even if they fire in the browser.

Follow-up/ongoing items:

  • Another user reports InitiateCheckout not firing (ATC fires instead). A response suggests the checkout flow or a unique/custom cart could be the cause, but no definitive fix provided.
  • Questions remain about ensuring proper tracking and Conversions API integration on custom Shopify themes.

Status: Original issue resolved by unblocking domain. Thread remains open with unresolved checkout-theme integration questions.
