Difference between number of impression pulled from the API and the ones from the DFP export log

[Mårten Rova]

Hi, 

Is there a known issue/feature in where the number of impressions in the DFP export impression log is in many cases slightly higher than the one pulled from the API. The API no of imps for a certain date seems lessen a little bit a one or two days after the delivery. 

1. Why do a small number of impressions seems to be 'uncounted' after a while in the API? 

2. Is there anyway to alter/reexport/add the exported impression log so that it align to the impression count in the API?

Kind rgds

Hi Mårten,

indeed, there is an explanation for this: Check out the Ad Manager Help Center:  

https://support.google.com/admanager/answer/1733124?hl=en

"Discrepancies with Ad Manager reporting"
Bad traffic, or spam data, is periodically removed from Ad Manager reports or API-generated reports. Due to the publishing schedule of Data Transfer files, some of this cleanup may not be reflected. This can result in Data Transfer showing slightly more impressions, clicks, or other events. When discrepancies occur, the extent tends to be ~1%.  

I hope this helps.

Hi Mårten,

Thank you for reaching out to us.

I would like to add that, if you were referring to Ad Manager reports instead of Data Transfer reports, you will want to align the ad unit view of both the UI and API report to one option (usually AdUnitView.FLAT). A discrepancy in the data should be expected otherwise, since the UI reports default to a FLAT hierarchy, while API reports default to a TOP_LEVEL one.

If the issue still exists despite the above (and if you are, in fact, referring to Ad Manager reports in the first place), then you may provide the details below (via Reply to author, or a direct, private reply to this email) so that I can further investigate the issue:

• Network code
• Complete SOAP request & response logs (SOAP logging must be enabled)
• Screenshots of the equivalent UI report options
