Hi Takeshi, I guess I was not clear enough (regarding the first question) as it's not exactly what I was asking...
Basically, for Display campaigns only, I can specify what bid dimension should be used for particular ad group. Thus, I can set AdGroup.contentBidCriterionTypeGroup = CriterionTypeGroup.PLACEMENT // use placements bids OR AdGroup.contentBidCriterionTypeGroup = CriterionTypeGroup.KEYWORD // use keywords bids OR etc... As you confirmed AdGroup.contentBidCriterionTypeGroup is not mandatory when creating a new group and if it's not provided then Ad Group level default bids are used. However, once AdGroup.contentBidCriterionTypeGroup gets to be set to PLACEMENT/KEYWORD/etc.. there is no way to reset it back to null, so that Ad group level default bids would be used again. I can definitely can do in UI, but (unless I am missing something) it seems like I cannot do it with the API.
