Hello, 

The AdGroupCriterionService and CampaignCriterionService are used to manage criteria both at Ad Group level and the Campaign level. You will be able to query for the criterion, modify bids and get the Campaign/AdGroup status. You may refer to this code sample which illustrates in detail on how to add keywords to an AdGroup using the AdGroupCriterionService. You may refer to the code sample which demonstrates on how to modify bids using the CampaignCriterionService. 

These code samples explains about these services and how they are used. I'd suggest that you take a look at these samples and let me know if you have any additional questions.
