Hey there Alex, sorry to open this again but I couldn't reply to the previous answer.

It's my understanding that this GA4 Source Data functionality, is dependent on both GA4 and on the user not having adblockers/advanced privacy blocking on.

The goal here is to have local/first-party data even when GA/FB/external scripts are blocked.

I'm in the final process of deciding on a Pixel Manager extension, and yours is looking much cleaner and performance minded than other bloated alternatives. The only thing I'm missing is this functionality.

It won't be a deciding factor, I'll probably just custom code it, but I believe it would be a good feature for Pixel Manager Pro. That could be further developed into a simple reporting/visualization tab similar to Payment Gateway Tracking Accuracy Report.

For me the main data would be utm_source and Landing page, that would give me a much better insight on where orders are coming from as since the iOS update GA/FB have plenty of under/over reporting issues.

Just wanted to make the suggestion more clear to you, you can go ahead and close this again

Best,
