问题
I'm trying to use the 'GetKeywordVariations' method of the google adwords API, documentation at this page. According to the documentation, it should return these fields, including lastMonthSearchVolume. When I try this, i get all the fields except for lastMonthSearchVolume. Does anyone know why?

I found the answer. i was using the older version of the API. Updating to the latest version fixed it .
