Error when creating Display Campaign - CANNOT_ATTACH_BIDDING_STRATEGY_TO_CAMPAIGN: Cannot attach bidding strategy to campaign.

[Антон Бендриков]

Hello,

when attempting to create a Display Campaign with advertising_channel_type "DISPLAY", I get the following error:

error_code: {bidding_error: "CANNOT_ATTACH_BIDDING_STRATEGY_TO_CAMPAIGN"}

message: "Cannot attach bidding strategy to campaign."

trigger: {string_value: ""}

Campaign parameters:

{

  advertising_channel_type: "DISPLAY",

  bidding_strategy: "customers/1275322088/biddingStrategies/7743946871",

  campaign_budget: "customers/1275322088/campaignBudgets/8782279878",

  name: "Test Campaign",

  start_date: "2021-05-26"

}

The Bidding Strategy is created before that successfully:

{

  maximize_conversions: {},

  name: "Test Campaign Bidding Strategy (f4eX)"

}

Campaign Budget:

{

  amount_micros: 23000000,

  name: "Test Campaign Campaign Budget (9Yk7)"

}

---

This works if I use advertising_channel_type "SEARCH", for example.

Am I using the wrong type bidding strategy? I tried different ones but couldn't find one that seems to work.

Or is the issue elsewhere?

Thank you!

Hello,

It appears that the bid strategy that you are trying to apply to your display campaign is MAXIMIZE_CONVERSIONS. As you can see in this reference page, MAXIMIZE_CONVERSIONS works only with Search campaigns. You will need to use a strategy that is compatible with display campaigns.

Apologies, I thought I had checked that before posting...

Switching to bidding strategy:

{

  name: "Bidding Strategy (GJkF)",

  target_spend: {}

}

Worked.

Thank you!
