Hi, we are looking at tracking offline conversions for Google Ads and Google Forwarding Numbers (GFN), has anyone had any experience or any tips on how we can utilise RC to acheive this? I cant seem to find anything online in regards to this and/or via RC support.

e.g a GFN will have a GCLID attached, and we need this added to the call coming in and when its converted into a sale, we can then send the offline conversion

Thanks

Ant
