Differences in metric's values between API report and Interface's report

[HernanF]

I'm pulling a daily ADGROUP_PERFORMANCE_REPORT through the API but I get different numbers than the interface report.

The API gave me less than 1% of differences than the interface. Sometimes the API's number is greater than interface and sometimes is smaller.

Any ideas? Is that normal?  Could be some TIME ZONE issue? 

thanks in advance!

HI,

The AdWords reports can sometimes differ between the API report and the UI report. This is due to Data Freshness. Some metrics are only calculated daily, which may cause some discrepancies. 

As a workaround, I suggest downloading your reports sometime after 3 a.m. (PST).

Regards,
