Hi Olivier, It appears that you are using the Campaign Performance Report <https://developers.google.com/adwords/api/docs/appendix/reports/campaign-performance-report>. You could download this by referring to our reporting guidelines <https://developers.google.com/adwords/api/docs/guides/reporting> or sample codes <https://developers.google.com/adwords/api/docs/samples/java/reporting> (also available in different languages) and compare the results to the UI. However, since the AdWords API only reflects the results shown in the Google Ads UI, you will not be able to see the differences. If you think that there are data discrepancies in your report, you could open your concern to the Advertiser's Community Forum <https://www.en.advertisercommunity.com/t5/Google-Ads/ct-p/google-ads#>, as the product experts are better equipped in answering your concerns.
