Hello,
If you're looking to pull stats at the ad level, you could use
Ad Performance Report where stats are generated at ad level with one row per ad. You can take a look at our
Reporting code samples in Java as a reference. Code samples in other languages can be found
here.
If you're having an issue generating the reports, could you please share the complete
report definition, so I can take a look? You can reply back via Reply privately to author option.
Thanks,
Bharani, AdWords API Team
