Hi,
I'm using the following code to update campaign bid:
/**
* Set campaign bid
* @param float $bid
* @param string $campaignId
* @param int $type , type is TARGET_CPA or TARGET_ROAS
* @return mixed
* @throws \Google\ApiCore\ApiException
* @throws \Google\ApiCore\ValidationException
*/
public function setCampaignBid($bid, $campaignId, $type)
{
// get campaign bidding strategy id
$fields = array('bidding_strategy.id');
$params = new GoogleAdsQueryParams();
$params->fromObject = 'campaign';
$params->fields = $fields;
$params->whereObjects = array('campaign.id');
$params->whereFields = array(array($campaignId));
$params->whereTokens =array(GoogleAdsQueryBuilder::EQUALS);
$params->limit =1;
$campaignObj = $this->executeGoogleAdsServiceQuery($params);
$biddingStrategyResource = $this->createCampaignBiddingStrategy($bid,
$type, $campaignObj? $campaignObj['bidding_strategy']['id']: null);
$campaign = new Campaign(['resource_name' =>
ResourceNames::forCampaign($this->account_google_id, $campaignId)]);
// Create campaign using an existing ID.
/** @var StringValue $biddingStrategyResource */
$campaign->setBiddingStrategy($biddingStrategyResource);
$campaignOperation = new CampaignOperation();
$campaignOperation->setUpdate($campaign);
$campaignOperation->setUpdateMask(FieldMasks::allSetFieldsOf($campaign));
$response = $this->campaignServiceClient->mutateCampaigns(
$this->account_google_id,
[$campaignOperation]
);
return $response->getResults()[0];
}
/**
* @param $bid
* @param $type
* @param null $campaignBiddingStrategyId
* @return string
* @throws \Google\ApiCore\ApiException
*/
private function createCampaignBiddingStrategy($bid, $type,
$campaignBiddingStrategyId = null): string
{
$biddingStrategy = new BiddingStrategy();
if ($campaignBiddingStrategyId)
{
$biddingStrategy->setId($campaignBiddingStrategyId);
}
$biddingStrategy->setType($type);
if ($type == BiddingStrategyType::TARGET_ROAS)
{
$targetRoas = new TargetRoas(['target_roas' => $bid]);
$biddingStrategy->setTargetRoas($targetRoas);
}
else
{
$money = new Money();
$bidValue = new Int64Value();
$bidValue->setValue($bid);
$money->setAmountMicros($bidValue);
$targetSpa = new TargetCpa(['target_cpa_micros' =>
$money->getAmountMicros()]);
$biddingStrategy->setTargetCpa($targetSpa);
}
// create operation
$biddingStrategyOperation = new BiddingStrategyOperation();
if ($campaignBiddingStrategyId)
{
$biddingStrategyOperation->setUpdate($biddingStrategy);
}
else
{
$biddingStrategyOperation->setCreate($biddingStrategy);
}
$response =
$this->biddingStrategyService->mutateBiddingStrategies($this->account_google_id,
[$biddingStrategyOperation]);
/** @var BiddingStrategy $mutatedBiddingStrategy */
$mutatedBiddingStrategy = $response->getResults()[0];
return $mutatedBiddingStrategy->getResourceName();
}
In the 1st function (setCampaignBid) I'm getting the campaign bidding
strategy id. If it's not null, I'm using it to get campaign bidding
strategy , if it does not exists, I'm creating it
(createCampaignBiddingStrategy).
After that, I'm using CampaignOperation to update/create campaign's bidding
strategy.
The problem is that I'm getting NULL when querying campaign's bidding
strategy (there is bidding strategy in the campaign I'm querying).
What I'm doing wrong?
