Why are only 40% of my purchase events being sent to analytics?

Topic summary

Significant drop in recorded purchase events since May 10–13: only 40–50% of orders are sent to Google Analytics (Universal Analytics and GA4). No code or app changes were made.

Observed behavior:

  • Successful tracked orders land on a post-purchase “thank you” page: /checkouts/c/…/thank_you.
  • Missing conversions end on an orders URL: /{store-id}/orders/{order-id} without reaching the thank you page.

Impact: Marketing campaigns are underperforming due to incomplete conversion data and disrupted platform learning.

Current status and responses:

  • Multiple users confirm the issue is ongoing.
  • Shopify support acknowledges the problem and says it’s under investigation with no update after more than a month.
  • Workarounds: Temporarily optimize/track earlier funnel events (e.g., Add to Cart, Add Payment Info). One user reports recovery after creating then deleting a Facebook Pixel event, reinstalling some apps, and contacting Facebook support, but the exact fix is unclear.

Key notes:

  • GA4 (Google Analytics 4) is Google’s current analytics platform; the “thank you” page is the post-purchase confirmation where conversion tags typically fire.

Resolution: Unresolved for most; root cause and definitive fix from Shopify remain unknown.
