Project: Fix Broken Shopify CAPI & Advanced Matching
I run a Shopify store (echomart.life) and use the official "Facebook & Instagram" app with the “Maximum” data-sharing level.
The Problem:
Browser (Pixel) events are sending, but no Conversions API (server) events are being received. This is confirmed in Meta's "Test Events" tool. Advanced Matching data is also not being sent.
This appears to be a complex bug, not a simple setup error. We have already tried all standard troubleshooting, including:
• A full uninstall and reinstall of the "Facebook & Instagram" app.
• Removing all manual fbq('init') pixel code from theme.liquid.
• Removing the Pixel ID from all other apps (like EasySell COD) to stop conflicts.
• Confirming Online Store > Preferences and Settings > Customer events are clean.
Despite a 100% clean setup, the official app is still failing to send server events.
What I Need:
1. Diagnose & Fix CAPI: Pinpoint why the official Shopify app is failing to send server events and reactivate them. (If the app is unfixable, be prepared to implement a new, stable CAPI connection, like GTM).
2. Ensure Full Deduplication: Make sure all standard events—PageView, ViewContent, AddToCart, Purchase—are sent from both browser and server and are correctly deduplicated with a matching event_ID.
3. Enable Advanced Matching: Ensure the setup correctly passes hashed email, phone, and name values to achieve a high Event Match Quality (EMQ) score.
4. Confirm & Hand-off: Confirm the final, working setup in Meta's "Test Events" tool and provide a concise note on what was fixed.
