Hello, this discrepancy seems to have existed for several years, I thought that I would post.
Pulling AUTOMATIC_PLACEMENTS_PERFORMANCE_REPORT will yield non-www. domains in the report for 'Domain'. For example,
google.com
However when using valuetrack {placement} in ads, a click may yield either
google.com or
www.google.com. However in the reports, it will not return the www. version and assign the click data to the other.
In short, it would be kind if the API placements report would reflect the same variable as valuetrack. Has anyone else noticed this, or is it an issue on my setup?
