Hello,
I'm trying to update a campaign's bidding strategy:
$biddingStrategy = new BiddingStrategy();
$biddingStrategy->setType($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 campaign using an existing ID.
$campaign = new Campaign([
'resource_name' => ResourceNames::forCampaign($this->account_google_id,
$campaign_pin_id),
'bidding_strategy' => $biddingStrategy
]);
$campaignOperation = new CampaignOperation();
$campaignOperation->setUpdate($campaign);
$campaignOperation->setUpdateMask(FieldMasks::allSetFieldsOf($campaign));
$response = $this->campaignServiceClient->mutateCampaigns(
$this->account_google_id,
[$campaignOperation]
);
return $response->getResults()[0];
The code below fails with "Expect Google\Protobuf\StringValue." error.
The reason is in the bidding_strategy assignment:
$campaign = new Campaign([
'resource_name' => ResourceNames::forCampaign($this->account_google_id,
$campaign_pin_id),
'bidding_strategy' => $biddingStrategy
]);
I tried to call $biddingStrategy->serializeToString() or
$biddingStrategy->serializeToJsonString() but it does not help.
How to assign the bidding strategy?
