How I clear CPC for Keyword in AdWords API (Java/v201609)?

[kan...@gmail.com]

I tried and succeeded at create CPC for keyword just that

https://developers.google.com/adwords/api/docs/samples/java/basic-operations#update-a-keyword

When I want to clear this CPC without remove keyword, how I can do that?

I tried

Operator.REMOVE at AdGroupCriterionOperation

 result... clear CPC with remove Keyword.

I tried too

Operator.SET at AdGroupCriterionOperation

Keyword keyword = new Keyword();
keyword.setId(keywordId);

BiddableAdGroupCriterion biddableAdGroupCriterion = new BiddableAdGroupCriterion();
biddableAdGroupCriterion.setAdGroupId(adGroupId);
biddableAdGroupCriterion.setCriterion(keyword);

BiddingStrategyConfiguration biddingStrategyConfiguration = new BiddingStrategyConfiguration();
CpcBid bid = new CpcBid();
bid.setBid(new Money(null, amount));
biddingStrategyConfiguration.setBids(new Bids[] {bid});
biddableAdGroupCriterion.setBiddingStrategyConfiguration(biddingStrategyConfiguration);

 result... update CPC in new amount

and replace bids

biddingStrategyConfiguration.setBids(new Bids[]{});

 result... no change

biddingStrategyConfiguration.setBids(new Bids[]{new CpcBid()});

 result... no change

change bid to null

bid.setBid(null);

 result... NullPointException

change Money.microAmount

new Money(null, null);

 result... NullPointException

new Money(null, 0);

 result... NullPointException

new Money(null, -1);

 result... BiddingErrors.BID_TOO_SMALL

Let me know how to clear keyword cpc from AdGroupCriterion please

Hi,

To remove a bid from a BiddingStrategyConfiguration, you need to update its bid field to a Money object with microAmount set to 0. When you use the example provided here to clear the bid this way, you'll encounter NullPointerException as the criterionCpcBid is assigned a value when the CpcBidSource is "CRITERION" and is otherwise null. When the operation to clear the bid is successful, the CpcBidSource is "ADGROUP" so criterionCpcBid will not be assigned a value. You need to modify the example to account for this when the response is processed. 

Let me know if this works.

Hi, Shwetha.

Yes, my CpcBidSource is 'CRITERION'. well, how i can change CpcBidSource?

In the first place, I want to return CpcBidSource to 'ADGROUP' after add keyword level CPC(It follows that CpcBidSource changed to 'CRITERION')

thank you.

Sorry,I got wrong idea earlier.

I delete

criterionCpcBid.getBid().getMicroAmount()

from my code.

Then, it works as my wish!

Thank you for your help!
