Google Ads API - Device type query is returning confusing results

[Dylan McBurnett]

Hello,

I have a query to get Device type for 4 campaigns in a single Account:

query_device = ( 'SELECT campaign.id, campaign.name, '

'segments.device '

'FROM campaign WHERE campaign.id =%s ') % account_campaign

When searching in UI for Device I can see all 4 Campaigns have devices 'Computers', 'Mobile phones', 'Tablets'. 

However my 'query_device' return MOBILE, DESKTOP, and TABLET for three of the Campaigns and returns nothing and no rows of data for the fourth campaign.

The exact same list of campaign Ids are returning the correct data for other values and the devices are all set at the Campaign Level.

Is there another way to query the Devices used in a Campaign?

I'm missing something but I don't know what..

Best,

Dylan

Hello Dylan, 

A device criteria for each device implicitly exists in each campaign, so you won't be able to ADD or REMOVE those criteria. Could you please share the request and response logs, so I can take a closer look? You can share the details privately via Reply privately to author option.

Thanks for the response (private)!

If there are no Impressions for a campaign(as in this case) then there will be no impressions across the devices - So a query of Devices will return empty for that campaign.

Hi Dylan,

Yes that's correct.

Thanks!
