Unknown Device value. Difference between API and Value Tracks

[lucas....@recargapay.com]

Hi

Ive noticed in the Adwords API documentation that the field Device for the campaign-performance-report, has 3 options. The usual computer, Mobile, Tablets AND a 4th one called Unknown. But when you see the options in the {device} Value Track you only have 3 options,  "m" for mobile (including WAP), "t" for tablet, and "c" for computer. The unknown clicks reported on the campaign-performance-report  what value have assigned on the {device} valuetrack?

Thanks

Hello,

UNKNOWN, in enumeration values in the AdWords API, is never intended to be used. It's there as a failsafe in case some bug or edge case causes a status we never anticipated. It is safe to ignore. There is no way to intentionally set anything to UNKNOWN or interact with it aside from seeing it in the very rare case where it arises naturally.
