Google Ads: update campaign bidding strategy

[integrations bidalgo]

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?

addition:

the query I'm sending to query campaign's bidding strategy id is:

SELECT bidding_strategy.id FROM campaign WHERE campaign.id = 1703363901 LIMIT 1

Hello, 

The bidding_strategy data is returned if you have Portfolio strategy associated with the campaign. It looks like the specific account has no Portfolio bid strategies in the account. You may use the campaign.bidding_strategy to pull the Campaign bid strategy details. 

Please let us know if you have any issues.

Thanks,
