Facing data mismatch between GA4 tracking and Google Ads conversion value
Hello
We are using the Weltpixel extension for GA4 tracking.
For measuring Google Ads conversion and conversion value, we have used Google Ads Core Data-layer.
Google Ads Data Console doesn't match GA4 or Google Ad Purchase Data when we verify it.
please see screenshot https://prnt.sc/m1GsNSajyjKf
Would you kindly offer some advice on how to fix this discrepancy?
Are there possibilities of conflict between the custom script and the Weltpixel extension?
Thanks

There are many factors which can influence this, however, as a general rule, we don't recommend using other custom tracking scripts when using our own extension (as would be the advice from any other vendor) as conflicts do have the possibility of arising.
If you're reporting transactions to Google Analytics via Measurement Protocol (server-side), these will be more accurate than client-side tracking scripts, which are often influenced by things like Cookie Policies, Ad Blockers, JavaScript browser settings, built in browser privacy settings, etc.
Here's an article that may help point you in the right direction: Magento 2 Google Tag Manager / Google Analytics 4 - Missing or incomplete transactions/revenue
