@imranshuvo i tested it and worked for me... but we are now back at using googletagmanager.com, instead of zaraz and hopefully when we can custom GoogleTag in cloudflare we will switch to that

1. trigger google ads on your conversion event, make sure you set in settings proper labels (conversion id and label and conversion linker)
2. pass custom fields: currency, revenue, transaction_id, user_data.email, user_data.phone with event property
3. make sure you send Consent Mode from event property _zarazGoogleConsentV2String

What's missing in steps above is passing these values from zaraz to gads, which is step 2

To confirm, see in zaraz debugger call to googleadservices.com/pagead/conversion/, as described here:
