I usually used utm_source / utm_medium to tracking the purchase/revenue related performance in the past. Recently I tried to evaluate the new marketing tool and I want to know its performance. However, I don't want to adjust the original utm_source / utm_medium and I prefer use a inpendent variable UTM-like tracking, is it possible to do the purchase/revenue tracking with self-defined dimension ?
Ideally I would like to select the Custom Dimension with medium/source in the attachment pic And I can tell the purchase/revenue of each medium/source
Last, Here is my goal : I would like to use the GA4 Data API ReportRequest function to get the metric data from each custom-dimension.
I find "See custom campaign data" described here https://support.google.com/analytics/answer/10917952?hl=en#zippy=%2Cin-this-article but I'm not sure whether it is the clue .
Thank you for the kindly support! Have a good day
