Hello Dannison,
Thanks for the reply. As a matter of fact, we do download the Campaign Performance Report to obtain the results :) Basically, for technical reasons on our side (among other things, aggregate results from multiple Adwords accounts), we prefer (for some metrics, not all) to calculate using parts of a calculated metric. For example, get the Cost and the Conversions separately, then re-calculating them. In that specific case, we do not obtain the same results as the Adwords UI. If the Conversion Rate displayed in the UI is different from the calculated metric using its parts, how can we find the correct numbers to do the calculation, in the API? Let me know :) On Wednesday, November 21, 2018 at 2:07:00 PM UTC-5, Dannison Yao (AdWords API Team) wrote: > > 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.
