Pretty much the way this works is: An AdGroupCriterion can either be Biddable or Negative.
A BiddableAdGroupCriterion has stats and bids associated with it. The stats fields that you can get for a biddable criterion are listed on this page with "Selectable" under their name: http://code.google.com/apis/adwords/docs/reference/latest/AdGroupCriterionService.Stats.html The desired fields get listed in the array of strings you pass into your Selector when you call get on the AdGroupCriterionService. The bids are a bit more complicated, you have to know what kind of bidding is used on the adgroup you are working with, if you are using ManualCPC bidding then you would get field names from here: http://code.google.com/apis/adwords/docs/reference/latest/AdGroupCriterionService.ManualCPCAdGroupCriterionBids.html Again, these desired fields are also passed into the Selector fields array at the AdGroupCriterion level. You do not have to qualify these fields using their wrapper objects. So for instance, if you wanted MaxCPC, Clicks, and Cost for a biddable keyword that uses ManualCPC bidding, you would pass in your selector an array of strings like this: {"Id","AdGroupId","KeywordText","MaxCpc","Cost","Clicks"} You have to know what you are working with in all cases, the type of bidding and type of criterion determine what fields are selectable and what the names of those fields are. -- =~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~ 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.
