Ryan, I suspect this has something to do with the fields you are selecting.
Both "startDate" and "endDate" are required, but I don't think this is the only issue. Something that is not obvious about the documentation is that members of a service object class are also selectable and may be required. What I mean here is that since you are selecting fields from CriterionBidLandscape, you may also be required to select fields from its child object BidLandscape.LandscapePoint to get a result. A BidLandscape is actually a collection of BidLandscape.LandscapePoint objects. In this case it is an Array of BidLandscape.LandscapePoint objects. So by requesting a CriterionBidLandscape without selecting the required field "bid" from the BidLandscape.LandscapePoint class, you are preventing yourself from getting any results. This goes for any service in the API. -- =~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~ Also find us on our blog and discussion group: http://adwordsapi.blogspot.com http://groups.google.com/group/adwords-api =~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~ You received this message because you are subscribed to the Google Groups "AdWords API Forum" group.
