Hi Yoav, Data generated from the Ad Performance Report <https://developers.google.com/adwords/api/docs/appendix/reports/ad-performance-report> could possibly be different with the Criteria Performance Report <https://developers.google.com/adwords/api/docs/appendix/reports/criteria-performance-report> as each report aggregate statistics at different entity levels. The former is at the ad level while the other is at the ad group criteria level.
As for the discrepancies with the generated statistics in the AdWords UI, could you reply to us privately (using *reply privately to author* option) with the report definitions <https://developers.google.com/adwords/api/docs/guides/reporting#create_a_report_definition> used for each report, the actual generated reports from the API, and the screenshot of the reports generated in the AdWords UI?
