Hi,
Thank you for contacting the Ad Manager API support team.
I have reviewed your query and understand that the mentioned metrics are available in version v202402, but not in v202405. I recommend you refer to this article( why it is deprecation.). To avoid double-counting conversions, Ad Manager counts a conversion as click-through if the user has clicked on an ad within the lookback window for clicks, even though the activity is also view-through. If there is no click recorded within the lookback window, the conversion is associated with the last eligible impression within the lookback window.
