Traffic source

Traffic source ^(Beta) 
Understand if a requested query is designated as purchased. Values include:

• Purchased: Traffic redirected from properties other than owned (acquired or otherwise incentivized activity)
• Organic: Direct URL entry, site search, or app download
• Undefined: Value not set in the GPT or mobile SDK

Note: Publishers must set the traffic source to "Purchased" or "Organic" on the ad request to see those values in reporting. If no value is set, we'll report "Undefined."
