Users are reporting low event match quality scores for Facebook Conversions API implementations through Shopify, despite setting customer data sharing to “Maximum.” Scores range from 4.6/10 to 7.9/10, with the original poster achieving 7.7/10.
Current Status:
Multiple users confirm experiencing similar low scores
No clear resolution has been identified in the thread
The discussion remains open with users seeking improvement strategies
Proposed Solution:
One user suggests abandoning Shopify’s native Facebook app tracking
Recommends implementing GTM (Google Tag Manager) and SGTM (Server-Side Google Tag Manager) as an alternative approach
The event match quality score measures how well customer data from the Conversions API matches Facebook user profiles, impacting ad targeting and attribution accuracy.

I implemented via Shopify the integration of the new Facebook Conversions API, and set the “Customer data sharing” to “Maximum”. When I check the pixel in my Facebook Business account, I see that the Purchase conversion score (Browser • Server) is 7.7/10.
