Hey peops,
I’m getting this message in the Match Quality screen on Facebook:
“Your server is sending an empty fbc parameter through Conversions API, but we observe a valid fbc parameter being received through Meta Pixel.”
When I check my server GTM in preview mode the fbc parameter is fully present and correct, and is being sent in the outgoing HTTP request to FB from sGTM.
What might be going on? Thanks
Hey @Van if you’ve checked the requests and see fbc there I’d say this is either a bug or a temp issues in FB UI. There’s nothing you can do on top of actually sending it 
After trying and trying I couldn’t find a fix. So you think it’s just a UI issue and that the fbc data is actually being sent?
If you see it in request body and you get a 200 response - you are sending it.
Ok that’s good to know. Thank you Dan
