Facebook Pixel Diagnostic: Redundant Purchase Events

[WhaleOfATime1]

The diagnostic tab for our Facebook pixel is showing redundant purchase events on a few checkout thank you page URLs so it may be incorrectly tracking purchase events on pages where purchases can’t be made. 

Has anyone else had this issue?

Duplicate Facebook purchase events can be a difficult thing to diagnose.

Firstly, what pixel solution are you using? That is vital to know. There are apps that can substitute for Shopify's standard pixel implementation or you may have your own through Google Tag Manager or embedded in your theme and checkout scripts.

Such issues are difficult to isolate because you want to be able to replicate the problem and you cannot always replicate.

We have seen Shopify's "Facebook" app/"Facebook" Sales Channel, causing a fbq() function responsible for the pixel, to fire duplicate events.

@Josh_Uebergang how it can be fixed? Do we need to delete fbq function or what? Please help out as our adds delivery is badly impacted and we are unable to resolve this issue for long even though we have contacted shopify direct support! Thank you.
