update/set maxcpc on one specific shopping product in an adgroup - google-ads-api

Question

I want to update my max cpc bid for a specific product in adwords.
Via the webui of adwords this is a trivial task, but I cant get it to work in code, this is what I have so far.
import com.google.api.ads.adwords.axis.factory.AdWordsServices;
import com.google.api.ads.adwords.axis.v201607.cm.*;
import com.google.api.ads.adwords.lib.client.AdWordsSession;
import com.google.api.ads.common.lib.auth.OfflineCredentials;
import com.google.api.client.auth.oauth2.Credential;
import java.rmi.RemoteException;
public class ChangeBidOnSpecificProduct {
public static void main(String[] args) throws Exception {
OfflineCredentials build = new OfflineCredentials.Builder()
.forApi(OfflineCredentials.Api.ADWORDS)
.fromFile()
.build();
Credential oAuth2Credential = build
.generateCredential();
// Construct an AdWordsSession.
AdWordsSession session = new AdWordsSession.Builder()
.fromFile()
.withOAuth2Credential(oAuth2Credential)
.build();
String accountId = "ACCOUNT_ID";
Long campaignId = Long.valueOf("CAMPAIGN_ID");
long adGroupId = Long.valueOf("ADGROUP_ID");
session.setClientCustomerId(accountId);
Money money = new Money(null, 40000L);
String productId = "9200000050670959";
changeBidViaApi(session, campaignId, adGroupId, productId, money);
}
private static void changeBidViaApi(AdWordsSession session, Long campaignId, long adGroupId, String productId, Money newValue) throws RemoteException {
ProductOfferId productOfferId = new ProductOfferId();
productOfferId.setValue(productId);
ProductScope productScope = new ProductScope();
productScope.setDimensions(new ProductDimension[] {productOfferId});
BiddableAdGroupCriterion biddableAdGroupCriterion = new BiddableAdGroupCriterion();
biddableAdGroupCriterion.setAdGroupId(adGroupId);
biddableAdGroupCriterion.setCriterion(productScope);
BiddingStrategyConfiguration biddingStrategyConfiguration = new BiddingStrategyConfiguration();
CpcBid bid = new CpcBid();
bid.setBid(newValue);
biddingStrategyConfiguration.setBids(new Bids[]{bid});
biddableAdGroupCriterion.setBiddingStrategyConfiguration(biddingStrategyConfiguration);
AdGroupCriterionOperation operation = new AdGroupCriterionOperation();
operation.setOperand(biddableAdGroupCriterion);
operation.setOperator(Operator.SET);
AdGroupCriterionOperation[] operations = new AdGroupCriterionOperation[]{operation};
AdWordsServices adWordsServices = new AdWordsServices();
AdGroupCriterionServiceInterface adGroupCriterionService =
adWordsServices.get(session, AdGroupCriterionServiceInterface.class);
AdGroupCriterionReturnValue result = adGroupCriterionService.mutate(operations);
}
}
Executing this results in an error: 'Unmarshalling Error: cvc-elt.4.2: Cannot resolve 'ns2:ProductScope' to a type definition for element 'ns2:criterion''.
This is the (anonimized) data that is send to google:

</ns2:bid>
</ns2:bids>
</ns2:biddingStrategyConfiguration>
</operand>
</operations>
</mutate>
</soapenv:Body>
</soapenv:Envelope>
Any suggestions as the reason for the error or what I'm doing wrong here?

Answer 1

I managed to get it working by accessing the adwords items as a graph, iterating it and changing it bid value when I find a match.
private static void changeBidViaApi(AdWordsSession session, long adGroupId, String productId, Money newValue) throws RemoteException {
AdWordsServices adWordsServices = new AdWordsServices();
ProductPartitionTree partitionTree =
ProductPartitionTree.createAdGroupTree(adWordsServices, session, adGroupId);
for (ProductPartitionNode node : partitionTree.getRoot().getChildren()) {
ProductPartitionNode productPartitionNode = node.asBiddableUnit();
try {
ProductOfferId dimension = (ProductOfferId) productPartitionNode.getDimension();
if (dimension != null) {
String productIdInShopping = dimension.getValue();
if (productId.equals(productIdInShopping)) {
Long newBid = newValue.getMicroAmount();
productPartitionNode.setBid(newBid);
}
}
} catch (Exception exception) {
exception.printStackTrace();
}
}
AdGroupCriterionServiceInterface adGroupCriterionService =
adWordsServices.get(session, AdGroupCriterionServiceInterface.class);
List<AdGroupCriterionOperation> mutateOperations = partitionTree.getMutateOperations();
if (mutateOperations.isEmpty()) {
System.out.println("Nothing to do.");
} else {
adGroupCriterionService.mutate(mutateOperations.toArray(new AdGroupCriterionOperation[0]));
}
}

This is the working source code. It changes bid (max cpc) of product partition group. It is written in php, but you can modify this code to java.
$adWordsServices = new AdWordsServices();
$session = $this->getSession();
$adGroupCriterionService = $adWordsServices->get($session, AdGroupCriterionService::class);
$operations = [];
$adGroupCriterion = new BiddableAdGroupCriterion();
$adGroupCriterion->setAdGroupId(22122723325); // id of my adgroup
$adGroupCriterion->setCriterion(new Criterion(302190832)); // id of partition group. you can get find this id in PRODUCT_PARTITION_REPORT in ID field (which full name is Criterion ID)
//
$bid = new CpcBid();
$money = new Money();
$money->setMicroAmount(((float)4)*1000000);
$bid->setBid($money);
$biddingStrategyConfiguration = new BiddingStrategyConfiguration();
$biddingStrategyConfiguration->setBids([$bid]);
$adGroupCriterion->setBiddingStrategyConfiguration($biddingStrategyConfiguration);
$operation = new AdGroupCriterionOperation();
$operation->setOperand($adGroupCriterion);
$operation->setOperator(Operator::SET);
$operations[] = $operation;
//
$adGroupCriterionService->mutate($operations);
