Discrepancy in Cost Data between Webview and Adwords API

[pat...@bellroy.com]

Here's the query I made on the API:

SELECT Cost,Clicks,Impressions,CampaignName,Id,Date
FROM CAMPAIGN_PERFORMANCE_REPORT
DURING 20140401,20140801

The cost reported for one of my campaigns on July 4th is significantly different between the web view and the API query.

Hi,

I'd recommend running the UI and API report once more at the same time, and checking if the numbers match. If it doesn't, then use the "Reply to Author" option to share with me

- The report request xml

- The API report

- The UI report

- The campaign name (or ID) for which you see a mismatch in stats.

I'll take a look,

Cheers,
