Suddenly got "REQUIRED_BUSINESS_NAME_ASSET_NOT_LINKED" upon creating a new Performance Max campaign

[lezhne...@gmail.com]

Out of thin air we observe rejection in campaig ncreation over API. A request  MutateCampaigns instantly returns:

"campaignError":"REQUIRED_BUSINESS_NAME_ASSET_NOT_LINKED"

"message": "Brand Guidelines is enabled. Performance Max campaigns with Brand Guidelines enabled require at least one business name to be linked as a CampaignAsset.",

All our other campaigns and ad accounts never showed that before. Our flow is to create a GPM campaign and provide logo and buisiness name at asset group creation.

Why is that happening? It worked for other ad accounts.

Found this line in the docs, so I guess that answers the problem:

• For new PMax campaigns the default value of Campaign.brand_guidelines_enabled is now true.

Hi,

Thank you for reaching out to the Google Ads API support team.

I understand that you are encountering the 'REQUIRED_BUSINESS_NAME_ASSET_NOT_LINKED' error while creating PMax campaign via the Ads API.

Yes, your understanding is correct. From Google Ads API v21, Performance Max campaigns automatically enable brand guidelines on all new Performance Max for online sales or lead generation (standard) and Performance Max for online sales with a product feed (retail) campaigns. Whereas the Performance Max for travel goals does not support brand guidelines. If you don't want to enable brand guidelines on your new campaigns, set Campaign.brand_guidelines_enabled to 'false' when creating your new Performance Max campaign.

Performance Max campaigns with brand guidelines enabled use campaign-level assets for brand asset field types (BUSINESS_NAME, LOGO, and LANDSCAPE_LOGO). You must link brand assets to the campaign using CampaignAsset, and the campaign must have:

• Exactly one BUSINESS_NAME asset
• At least one LOGO asset and up to four optional additional logo assets of the type LOGO or LANDSCAPE_LOGO

So, if you don't satisfy the above, the API will throw an error that you are encountering. I recommend you refer to the Blog Post and Release Notes for more information regarding this change. Follow the steps in this guide to create a Performance Max campaign via the API. 

I hope this helps.
 

Thanks,

Hello ! 

We encountered the same issue, while explicitly disabling brand guidelines in our campaign. I'm assuming it's due to the automatic migration process mentioned in this blog post. 

We would like to keep our campaigns without brand guidelines, and for that same reason, to know if the automatic migration process is still ongoing or if we should expect further discrepancies between our system and Google Ads one.

Could you let us know about that ? 

Thank you very much,

Regards

As per the Blog Post, please note that we expect the automatic migration will be completed for all relevant CIDs by October 30th, 2025.

Hi ! 

Even though the automatic migration is supposed to be completed (as stated in this blog post), we still have campaigns that get migrated automatically to enabling brand guidelines without any action from us (besides creating a second asset group in the same performance max campaign). It goes without saying that when creating the campaigns, we disable brand guidelines explicitly.

Is the automatic migration a permanent feature ?

Hi,

As per the blog post, the migration was suppossed to be completed for all applicable CIDs by October 30th. Please provide us with the campaign Id which got migrated automatically to enabling brand guidelines.

Also, please confirm that campaigns created with campaign.brand_guidelines_enabled to 'false' explicitly also got migrated? If yes, please provide us the campaign Id. This would help us investigate this issue further.

You can send the details via Reply privately to the author option, or direct private reply to this email.

Support through the Google Ads API forum will no longer be provided starting on January 28, 2026. Reach out directly to googleadsa...@google.com for any future technical support issues regarding the Google Ads API.
