Good NumbersMeta Conversions API on Shopify, deduplicated and matched properly.
We set up the Conversions API alongside your Meta pixel so every Shopify purchase reaches Meta once, with the right value and enough customer data to match it to the ad.
- No duplicate purchases
- Event Match Quality checked per event
- Fixed price after a free check
Most Shopify CAPI setups are on, but not right.
Turning on the Conversions API takes a few clicks. Making it count every order once, with values that match Shopify and customer data Meta can match, is where most stores fall short.
- Duplicate purchases
- The pixel and the server send different event IDs, so Meta counts orders twice and reported ROAS is inflated.
- Low Event Match Quality
- Purchases sent without email, phone or click IDs are hard for Meta to tie to an ad.
- Wrong values
- Tax, shipping, discounts or currency handled differently from Shopify.
- Too many sources
- The Facebook and Instagram app, a theme pixel, GTM and an app all sending purchases at once.

Common questions
Anything else, ask in the free check form or email hello@goodnumbers.io.
Is Shopify's Facebook and Instagram app enough for the Conversions API?
For many stores, yes, when its data sharing is set to the highest level and nothing else is sending purchases to the same pixel. We check that first and only add a tracking app or server-side GTM when there is a real gap.
Why does Meta show more purchases than Shopify?
Part of it is attribution: Meta counts purchases within its click and view windows. Part can be duplicate events, which we fix. Our guide on Meta versus Shopify revenue explains the difference.
What is a good Event Match Quality score?
For purchases, aim for 8 or above out of 10. Scores improve when you send more customer information parameters with each event.
Will this change my reported ROAS?
Removing duplicates lowers inflated numbers, and better matching recovers real purchases. The goal is a number that matches what actually happened, so budget decisions hold up.
How long does it take?
Usually one to two weeks including testing and a short monitoring period.
