HI @Antoine99 welcome to the Shopfy Community,
Can you please share the store url so that i can look into the analytics tags and find out the issue for you.
Thanks
Topic summary
Main issue: Large mismatch between Facebook Ads reporting (53 unique link clicks) and Shopify Analytics (16 visitors from Facebook/Instagram), plus a recorded purchase not appearing in Shopify metrics (0 add-to-cart, 0 initiate checkout, 0 sales despite 1 sale).
Investigation: A community member asked for the store URL; the store owner shared viesion.shop.
Update: The store owner reports the discrepancy appears resolved after changing data-sharing settings and product catalog configuration linked to Facebook. They now see matching tracking events.
Details mentioned as potential fixes:
- Adjusted cookie/consent parameters to capture tracking data broadly (collecting cookies even without explicit acceptance).
- Verified the Facebook product catalog (product feed used by Facebook Ads) is correctly connected to the Facebook app.
Follow-up: Another user with the same issue requested the exact fix. A subsequent question asked how to collect cookies without user acceptance. No answer yet.
Status: Tentatively resolved for the original poster via settings changes; no definitive, step-by-step solution provided. Discussion remains open with unanswered consent/cookie implementation questions.
