Hi Wendy,
AdWords API reports contain the same data that you see in the AdWords UI. I'm not an expert in DFA, but if you see differences between the AdWords UI and the DFA UI, you will see those same differences in API reports.
If you have further questions about this topic, you may want to post to the
AdWords Community, as the experts there may have further insights.
Cheers,
Josh, AdWords API Team
