Ads Percentage Served Value - Reporting

Where is the percentage served field?

I.e., if we have multiple ads in an ad group, in AdWords you can add the column showing the first ad was displayed 52% of the time and the other ad 48% of the time.

Hi Justin,

All the fields available in the AdWords UI are not mapped to the AdWords API reports. You could probably use the impressions received by an Ad and divide by the total impressions received by the corresponding AdGroup to calculate the percentage served value.
