Modify target cpa on app campaign

[Yudi Xue]

Hello,

We have a few App Campaigns that we would like to update TargetCpa value via API:

campaign {

  resource_name: "customers/xxxxxxxxx/campaigns/xxxxxxxxxx"

  id {

    value: 1748163543

  }

  name {

    value: "App-1"

  }

  status: ENABLED

  campaign_budget {

    value: "customers/xxxxxxxxx/campaignBudgets/xxxxxxxxxx"

  }

  advertising_channel_sub_type: APP_CAMPAIGN

  bidding_strategy_type: TARGET_CPA

  target_cpa {

    target_cpa_micros {

      value: 80000000

    }

  }

}

I found that we could not modify target_cpa with campaign mutate operations from google ads sdk:

AttributeError: Assignment not allowed to field "target_cpa" in protocol message object.

Can we modify target_cpa for app campaign with googleads sdk? 

What can I do to modify that via API?

Thank you!

Hello Yudi, 

You will be able to update the App Campaigns TargetCpa value by setting the cpc_bid_floor_micros value. Could you please give this a try and let us know if you have any issues?

Thanks,
