Update campaign optimization bidding strategy

[Roman Ryazanov]

Hey,
I'm trying to update the campaign optimization bid strategy:

$campaign_data = [];
$campaign_data['resource_name'] = ResourceNames::forCampaign($account_id, $camapign_id);
$campaign_data['app_campaign_setting'] = new AppCampaignSetting();



$campaign_setting = new AppCampaignSetting();
$campaign_setting->setBiddingStrategyGoalType(3);

$campaign_data['app_campaign_setting'] = $campaign_setting;

$campaign = new Campaign($campaign_data);
$campaignOperation = new CampaignOperation();
$campaignOperation->setUpdate($campaign);

and getting this error:

[{"errorCode":{"requestError":"IMMUTABLE_FIELD"},"message":"Field 'app_campaign_setting.app_id' cannot be modified by 'UPDATE' operation.","location":{"fieldPathElements":[{"fieldName":"operations","index":"0"},{"fieldName":"update"},{"fieldName":"app_campaign_setting"},{"fieldName":"app_id"}]}},{"errorCode":{"requestError":"IMMUTABLE_FIELD"},"message":"Field 'app_campaign_setting.app_store' cannot be modified by 'UPDATE' operation.","location":{"fieldPathElements":[{"fieldName":"operations","index":"0"},{"fieldName":"update"},{"fieldName":"app_campaign_setting"},{"fieldName":"app_store"}]}}]







I'm not trying to update the store id or app id - only the optimization bid strategy.
Is it possible to do it through the api?

Thank you.

Hi Roman,

Thank you for reaching out. Can you please provide the complete request and response logs of the call via reply privately to author? You can find information on enabling logging here.

Based on the code you provided, it looks like you are creating the AppCampaignSettings twice which could be causing the error.
