asset_link_error when trying to ad image asset to adgroup in google ads api (php)

[Shawn Naquin]

When I try to link an image asset to an AdGroup in php with the Google Ads PHP library I get the message:

(php 7.4, google-ads-api v8, grpc with composer library googleads/google-ads-php ^12)

asset_link_error: The given field type is not supported to be added directly via asset links.

The below code is taken straight from the docs

// create & upload the asset
$imageAsset = new Asset(
    [
        'name' => $imageUrl,
        'type' => AssetType::IMAGE,
        'image_asset' => new ImageAsset(
            [
                'data' => file_get_contents($imageUrl)
            ]
        )
    ]
);

...after sending the creation as an operation, the asset creation is then sent successfully, and I can successfully query for the newly created asset.

// Creates an operation to add the asset to the adgroup.
$adGroupAsset = new AdGroupAsset(
[
    'ad_group' => $adGroupResourceName,
    'asset' => $assetResName,
    'field_type' => AssetFieldType::MARKETING_IMAGE,
    'status' => AssetLinkStatus::ENABLED,
]
);

$adGroupAssetOperation = new AdGroupAssetOperation();
$adGroupAssetOperation->setCreate($adGroupAsset);

$adGroupAssetServiceClient = $this->googleAdsClient->getAdGroupAssetServiceClient();
$response = $adGroupAssetServiceClient->mutateAdGroupAssets(
    $this->clientId,
    [$adGroupAssetOperation]
);

I checked, and I can add an image link manually to this same adgroup in the UI!

Any help would be appreciated, there's not much info about this error in the docs or how to go about adding image extensions to an adgroup.

Thanks,
Shawn

Hi Shawn,

Thank you for reaching out to our API support team.

Could you confirm if what you intend to do is use assets in ads? If yes then the link you provided should indeed be the appropriate guide.

However, since you appear to be using the AdGroupAssetService, then its typical usage is for creating asset based extensions as discussed here.

Hi,

I am trying to do the same(adding image extension to adgroup).

//adgroupassetOperation
$adGroupAssetOperation = new AdGroupAssetOperation([
'create' => new AdGroupAsset([
'asset' => $imageAssetResourceName,
'field_type' => AssetFieldType::MARKETING_IMAGE,
'ad_group' => ResourceNames::forAdGroup($clientId, $adGroupId)
])
]);

$adGroupAssetServiceClient = $this->googleAdsClientSession->getAdGroupAssetServiceClient();
$response = $adGroupAssetServiceClient->mutateAdGroupAssets($clientId, [$adGroupAssetOperation]);

I am getting the same error : The given field type is not supported to be added directly via asset links.

assetLinkError: UNSUPPORTED_FIELD_TYPE

stringValue: MARKETING_IMAGE

could anyone help?

Hi Shirley,

Please note that the CampaignAsset, AdGroupAsset and CustomerAsset works only for assets that are associated with an Extension.

Hi Aryeh,

Thank you for the information. I have followed the same documentation. But getting the same error

1. Create ImageAsset for ImageExtension

// Creates an asset.
$asset = new Asset([
'type' => AssetType::IMAGE,
'image_asset' => new ImageAsset(['data' => $imageContent])
]);

// Creates an asset operation.
$assetOperation = new AssetOperation();
$assetOperation->setCreate($asset);

// Issues a mutate request to add the asset.
$assetServiceClient = $this->googleAdsClientSession->getAssetServiceClient();
$response = $assetServiceClient->mutateAssets(
$clientId,
[$assetOperation]
);
if (!empty($response->getResults())) {
$addedImageAsset = $response->getResults()[0];
return $addedImageAsset->getResourceName();
}

2. Add asset to AdGroup

//adgroupassetOperation
$adGroupAssetOperation = new AdGroupAssetOperation([
'create' => new AdGroupAsset([
'asset' => $imageAssetResourceName,
'field_type' => AssetFieldType::MARKETING_IMAGE,
'ad_group' => ResourceNames::forAdGroup($clientId, $adGroupId)
])
]);

$adGroupAssetServiceClient = $this->googleAdsClientSession->getAdGroupAssetServiceClient();
$response = $adGroupAssetServiceClient->mutateAdGroupAssets($clientId, [$adGroupAssetOperation]);

Could you please point out what is missing?

Thanks

Hi Shirly,

Thank you for providing additional details.

Image assets can be set for certain types of ads, as seen here. However, it currently cannot be used for extensions.

Listed here are the asset based extensions that are currently supported and can be created/managed via the API, and stating that other types would follow later. For now, you may keep an eye on our blog for updates or announcements on when image extensions can be included.

If you wish to create image extensions for your account, you may reach out to the Google Ads Product Support team instead, via this link, to confirm whether this is already possible via the Google Ads UI.

I hope this helps.

Hello there.

I have the same error. Here https://developers.google.com/google-ads/api/docs/extensions/extensions it is stated that feed items are deprecated but still can't use the new way to link assets. When it is planned to support Image type assets?

[Google Ads API Forum Advisor]

Hello Algirdas,

Thank you for reaching out to us.

As mentioned by my colleague (Peter) on the previous thread, currently supported asset based extensions are listed here and other types would follow later. In the meantime, we recommend that you keep an eye to our blog for future updates or any announcements on when image extensions can be included.
