Hi Werner,
Thank you for the replies.
In order to get the maxCPC bids, I recommended that you follow this
report then include this
field. As for setting of maxCPC, you can use the
update operation of the
AdGroupCriterionOperation to change the
cpc_bid_mircos field of the AdGroupCriterion specifically of the keywords.
Let me know if you have further questions with the provided documents.
