Main issue: Facebook Pixel events on a Shopify store aren’t tracking correctly; the server-side event_source_url is being blocked, and the cause (Shopify vs. Meta vs. setup) is unclear.
Attempts so far: Reconnected the Pixel, reinstalled the Shopify Facebook & Instagram app, and reviewed Events Manager, but the pixel still doesn’t fire reliably.
Explanation provided: Meta may block the server event_source_url if it’s incomplete or appears risky/sensitive. This value is sent by Shopify by default and generally isn’t user-adjustable.
Recommended checks:
Confirm both browser and server events are firing for key actions in Meta Events Manager.
Use Test Events to isolate where the tracking flow breaks.
Remove any duplicate pixels or conflicting apps.
Double-check URL parameters; sensitive values can trigger blocking.
Next steps if unresolved:
Contact Shopify and Meta support.
Consider switching to a specialized Meta pixel app instead of the Shopify Facebook & Instagram app; an alternative can be suggested.
Status: No resolution yet; action items outlined and discussion remains open.

Hi everyone, I’m struggling a bit with my Facebook Pixel setup and I’m hoping someone here has run into this before. I’ve tried reconnecting the Pixel, reinstalling the Shopify Facebook & Instagram app, and checking my Events Manager… but some events still aren’t tracking correctly. In my case, the server-side event_source_url keeps getting blocked, and I can’t tell whether the issue is coming from Shopify, Meta, or my setup.
I’ve watched a few tutorials and followed several troubleshooting steps, but no matter what I try, the pixel still isn’t firing the way it should. Has anyone found a simple or reliable way to fix these kinds of tracking issues? Any guidance or clear steps would be super appreciated — I feel like I’m missing something small but important.
this issue occurs when meta’s systems detect that the server event_source_url is incomplete or appears to be risky (or should i see sensitive or harmful in nature.)
shopify sends this value by default, so you cannot adjust it in your setup.
here’s what i can suggest trying:
you should first check Meta Events Manager and confirm if both browser and server events are getting triggered/firing for all the key actions.
then, please use Test Events in your Meta account to identify where is the tracking flow breaking exactly.
additionally, if there are any duplicate pixels or other apps that might causing conflicts, remove them.
also, double check your URL parameters. as i shared earlier, if there is anything sensitive, meta will block it.
if the issue still continues after these checks, then there are two things you can do:
contact shopify and meta’s support team
shift toward another specialized meta pixel app as the facebook and instagram app can be causing this issue specifically. would you be open to making that shift? if yes, then let me know so that i can suggest another app
