Update headlines in an asset group

[Gionni Lone]

Hi, I'm struggling to update headlines in an existing asset group, belonging to a perf max campaign. I need to replace those which have a "Low" performance label. I don't know if I should first delete the headlines I want to replace and then create the new ones. This is what I tried and the error:

googleads_service = self.get_service("GoogleAdsService")
asset_group_service = self.get_service("AssetGroupService")
headlines_resource_names = self._create_multiple_text_assets(account_id, asset_list)
asset_group_asset_operation = self.get_type("AssetGroupAssetOperation")
asset = asset_group_asset_operation.update
asset.resource_name = asset_group_service.asset_group_path(account_id, asset_group_id)
operations = []
for resource_name in headlines_resource_names:
         mutate_operation = self.get_type("MutateOperation")
         asset_group_asset = mutate_operation.asset_group_asset_operation.create 
         asset_group_asset.field_type =               self.get_type('AssetFieldTypeEnum').AssetFieldType.HEADLINE
         asset_group_asset.asset_group = asset.resource_name
         asset_group_asset.asset = resource_name
        operations.append(mutate_operation)

fm = protobuf_helpers.field_mask(None, asset._pb)
asset_group_asset_operation.update_mask.CopyFrom(fm)

for operation in operations:
         ad_group_ad_response = googleads_service.mutate(
         customer_id=str(account_id), mutate_operations=[operation]
)

And this is the error I received:

Hi Gionni,

Thank you for raising this concern to the Google Ads API Forum.

Upon checking the provided logs, I can see that you are encountering the headline limit for asset groups. According to this document, you can only add up to 5 headlines for the asset group. However, upon checking the counts of linked headlines to your asset group using the query below, I can see that you already exceeded the limit. This is the possible reason why the error persists. 

SELECT asset.id, asset_group_asset.status FROM asset_group_asset WHERE asset_group.resource_name = \"customers/1489840023/assetGroups/6442638580\" AND asset_group_asset.field_type ="HEADLINE"

Hi, thank you for your reply. 

I know the maximum number I can have per asset is 5, but what I want to do is replacing them. With RSA when I wanted to replace them I would  just upload other 15 headlines and they get correctly replaced, but in this case it says "exceeded the limit". Can you please tell me whats the correct way of replacing those assets?

Thank you

I also tried to update a single asset in this way, but received an error:

       asset_group_service = self.get_service("AssetGroupAssetService")

       asset_group_asset_operation = self.get_type("AssetGroupAssetOperation")
       asset = asset_group_asset_operation.update

       asset.resource_name = asset_resource_name
       asset.asset = new_text
       asset.field_type = self.get_type('AssetFieldTypeEnum').AssetFieldType.HEADLINE

       fm = protobuf_helpers.field_mask(None, asset._pb)
       asset_group_asset_operation.update_mask.CopyFrom(fm)

       asset_group_service.mutate_asset_group_assets(
       customer_id=account_id, operations=[asset_group_asset_operation]

Hi Gionni,

Thank you for the reply. Could you please provide more details where you exactly encounter the behavior below? I asked this because in the Google Ads API, once you have uploaded 5 enabled headlines, it is no longer possible to add more headlines because of the product level document that you provided.

"I know the maximum number I can have per asset is 5, but what I want to do is replacing them. With RSA when I wanted to replace them I would just upload other 15 headlines and they get correctly replaced, but in this case it says "exceeded the limit". Can you please tell me whats the correct way of replacing those assets?"

For the mutable error you encountered, the mutable field or field that you can update is the status in the object of AdGroupAsset.

Best regards,

Hi,

I figured that in order to replace assets like headlines I need first to delete the headline I want to replace and then add the new one. That worked, thank you.
