FB Pixel firing purchase, but zero purchases in Shopify

Shopify Discussion
,

Topic summary

A store owner reports a discrepancy where Facebook Pixel shows 3 purchases, but Shopify dashboard displays zero sales. This issue affects two stores created within the past 15 days.

Troubleshooting attempts (unsuccessful):

  • Created new Facebook Pixel
  • Created new Facebook Business Manager
  • Created new Facebook fan page
  • Assigned FB Pixel via both code and app integration

The owner’s test purchases register correctly in Shopify, suggesting the issue affects only external customer transactions. They haven’t yet tried changing the store theme, wondering if theme code could be related.

Suggested solutions:

  • Implement Facebook Pixel through Shopify’s custom pixel feature in customer events (newer, more reliable method)
  • Consider using attribution platforms like Attribuly for more accurate conversion tracking and Facebook Ads Manager integration

The discussion remains open with the store owner seeking additional guidance on resolving the tracking mismatch.

Hello,

Facebook is showing that I had 3 sells yesterday, but when I check in my Shopify dashboard, it shows zero purchases. Please check photos attached.

I did few purchased in my Stores and all of them were reported in Shopify / Gateway without problems.

I´m facing this exactly same issue in 2 stores that I have created in the past 15 days.

I have already tried the following possible solutions, but without success:

  1. Created a new FB Pixel;

  2. Created a new FB Business Manager;

  3. Created a new FB fan page;

  4. Assign the FB Pixel in my Shopify stores by code and by app.

The only thing that I have not tried yet is to change the Store´s theme.

Do you guys know if the theme´s code can be related to this issue?

Do you have any suggestion?

Looking forward to your answers.

Thanks a lot!

Hey @bomfimcaio ,

As you mentioned it’s a quite common issue since browser-based tracking code frequently errors.

1, Have you tried custom pixel in customer events of Shopify admin? It should be a better way to track the purchase for Facebook pixel.

2, If your target is converson tracking and attribution. I would suggest Attribuly, this Shopify customer events( new Shopify feature) integration makes sure you get highest accurate conversion tracking in maket. It supports integration with Facebook ads manager as well.

Thanks.
