Extension Setting Services

Important: All extensions will soon become Asset-based extensions. Asset-based extensions will not be supported in the AdWords API. We strongly recommend migrating your extensions to Asset-based extensions and managing them through the new Google Ads API as soon as is feasible. See the announcement for important dates and useful resources.

Note: This guide explains how to manage ad extensions using the extension setting services. If you wish to manage your existing feed-based ad extensions, see the feed services documentation instead.

Using extension setting services

Note: Since their data elements can be very large, extension setting services have an operations-per-request limit of 250 (instead of the usual 5,000).

As an example, suppose you're advertising a restaurant in Google Ads and want to add some extra information to its Google Ads campaign:

• Store hours: This link takes users to http://www.example.com/storehours.
• Nutrition data: This link takes users to http://www.example.com/menu/nutritiondata, where nutritional information about menu items is listed.
• Happy hours: This link takes users to http://www.example.com/happyhours, and should only be shown during these hours: 6pm to 9pm, Monday through Friday; and 5pm to 8pm on Saturday.
• Thanksgiving special: You plan to have a special Thanksgiving menu from November 27 to 28. This link should be displayed only from November 20 to 27 so users can make their reservation at http://www.example.com/thanksgiving.

Each of the items above is an ad extension in AdWords. You can manage extensions using the extension setting services in the AdWords API.

Adding ad extensions

Ad extensions can be added at the account, campaign, or ad group level, though not all extension types are available at all levels. For new ad extensions, use either the ADD or SET operator. If the SET operator is used in a case where an ad extension does not exist, a new ad extension is added. Ad extensions come in several formats.

Sitelink extensions

You can use sitelinks to link to specific subpages within your site, aside from your main landing page, making your site easier to navigate for users.

The following code snippet shows how to add new ad extensions to a campaign using CampaignExtensionSettingService.

Call extensions

You can list a business phone number alongside your ads that customers can call directly from the ad, using a CallFeedItem extension. The following code snippet shows how to do this:

Java

CallFeedItem callFeedItem = new CallFeedItem();
callFeedItem.setCallCountryCode("US");
callFeedItem.setCallPhoneNumber("212-565-0000");

CampaignExtensionSetting campaignExtensionSetting = new CampaignExtensionSetting();
campaignExtensionSetting.setCampaignId(campaignId);
campaignExtensionSetting.setExtensionType(FeedType.CALL);
ExtensionSetting extensionSetting = new ExtensionSetting();
extensionSetting.setExtensions(new ExtensionFeedItem[] {callFeedItem});
campaignExtensionSetting.setExtensionSetting(extensionSetting);

C#

CallFeedItem callFeedItem = new CallFeedItem();
callFeedItem.callCountryCode = "US";
callFeedItem.callPhoneNumber = "212-565-0000";

CampaignExtensionSetting campaignExtensionSetting = new CampaignExtensionSetting();
campaignExtensionSetting.campaignId = campaignId;
campaignExtensionSetting.extensionType = FeedType.CALL;
ExtensionSetting extensionSetting = new ExtensionSetting();
extensionSetting.extensions = new ExtensionFeedItem[] { callFeedItem };
campaignExtensionSetting.extensionSetting = extensionSetting;

Python

call_feed_item = {
    'xsi_type': 'CallFeedItem',
    'callCountryCode': 'US',
    'callPhoneNumber': '212-565-0000'
}

campaign_extension_setting = {
    'campaignId': campaign_id,
    'extensionType': 'CALL',
    'extensionSetting': {
        'extensions': [call_feed_item]
    }
}

PHP

$callFeedItem = new CallFeedItem();
$callFeedItem->setCallCountryCode("US");
$callFeedItem->setCallPhoneNumber("212-565-0000");

$campaignExtensionSetting = new CampaignExtensionSetting();
$campaignExtensionSetting->setCampaignId($campaignId);
$campaignExtensionSetting->setExtensionType(FeedType::CALL);
$extensionSetting = new ExtensionSetting();
$extensionSetting->setExtensions([$callFeedItem]);
$campaignExtensionSetting->setExtensionSetting($extensionSetting);

Callout extensions

The callout ad extension lets you provide additional details, such as what products or services you offer, using text right below your search ads. The following code snippet shows how to create a callout extension:

Java

CalloutFeedItem freeDeliveryCallout = new CalloutFeedItem();
freeDeliveryCallout.setCalloutText("Free delivery");

CalloutFeedItem kidsCallout = new CalloutFeedItem();
kidsCallout.setCalloutText("Kids eat free");

CampaignExtensionSetting campaignExtensionSetting = new CampaignExtensionSetting();
campaignExtensionSetting.setCampaignId(campaignId);
campaignExtensionSetting.setExtensionType(FeedType.CALLOUT);
ExtensionSetting extensionSetting = new ExtensionSetting();
extensionSetting.setExtensions(new ExtensionFeedItem[] {freeDeliveryCallout, kidsCallout});
campaignExtensionSetting.setExtensionSetting(extensionSetting);

C#

CalloutFeedItem freeDeliveryCallout = new CalloutFeedItem();
freeDeliveryCallout.calloutText = "Free delivery";

CalloutFeedItem kidsCallout = new CalloutFeedItem();
kidsCallout.calloutText = "Kids eat free";

CampaignExtensionSetting campaignExtensionSetting = new CampaignExtensionSetting();
campaignExtensionSetting.campaignId = campaignId;
campaignExtensionSetting.extensionType = FeedType.CALLOUT;
ExtensionSetting extensionSetting = new ExtensionSetting();
extensionSetting.extensions = new ExtensionFeedItem[] { freeDeliveryCallout, kidsCallout };
campaignExtensionSetting.extensionSetting = extensionSetting;

Python

free_delivery_callout = {
    'xsi_type': 'CalloutFeedItem',
    'calloutText': 'Free delivery'
}

kids_callout = {
    'xsi_type': 'CalloutFeedItem',
    'calloutText': 'Kids eat free'
}

campaign_extension_setting = {
    'campaignId': campaign_id,
    'extensionType': 'CALLOUT',
    'extensionSetting': {
        'extensions': [free_delivery_callout, kids_callout]
    }
}

PHP

$freeDeliveryCallout = new CalloutFeedItem();
$freeDeliveryCallout->setCalloutText('Free delivery');

$kidsCallout = new CalloutFeedItem();
$kidsCallout->setCalloutText('Kids eat free');

$campaignExtensionSetting = new CampaignExtensionSetting();
$campaignExtensionSetting->setCampaignId($campaignId);
$campaignExtensionSetting->setExtensionType(FeedType::CALLOUT);
$extensionSetting = new ExtensionSetting();

App extensions

If your business developed an Android or iOS app to target mobile users, you can display links to the app alongside your ads using an app extension. App extensions are shown only to users who are currently logged in to Google, and who haven't yet installed your app. Clicking the app extension link takes them to the Google Play or Apple iTunes page for your app. This code snippet shows how to create an app extension for an application on Google Play:

Java

AppFeedItem appFeedItem = new AppFeedItem();
appFeedItem.setAppId("com.example.mobileapp");
appFeedItem.setAppStore(AppFeedItemAppStore.GOOGLE_PLAY);
appFeedItem.setAppLinkText("Install our mobile app!");
UrlList finalUrlsList = new UrlList();
finalUrlsList.setUrls(
    new String[] {"https://play.google.com/store/apps/details?id=com.example.mobileapp"});
appFeedItem.setAppFinalUrls(finalUrlsList);

CampaignExtensionSetting campaignExtensionSetting = new CampaignExtensionSetting();
campaignExtensionSetting.setCampaignId(campaignId);
campaignExtensionSetting.setExtensionType(FeedType.APP);
ExtensionSetting extensionSetting = new ExtensionSetting();
extensionSetting.setExtensions(new ExtensionFeedItem[] {appFeedItem});
campaignExtensionSetting.setExtensionSetting(extensionSetting);

C#

AppFeedItem appFeedItem = new AppFeedItem();
appFeedItem.appId = "com.example.mobileapp";
appFeedItem.appStore = AppFeedItemAppStore.GOOGLE_PLAY;
appFeedItem.appLinkText = "Install our mobile app!";
UrlList finalUrlsList = new UrlList();
finalUrlsList.urls = new String[] {
  "https://play.google.com/store/apps/details?id=com.example.mobileapp"
};
appFeedItem.appFinalUrls = finalUrlsList;

CampaignExtensionSetting campaignExtensionSetting = new CampaignExtensionSetting();
campaignExtensionSetting.campaignId = campaignId;
campaignExtensionSetting.extensionType = FeedType.APP;
ExtensionSetting extensionSetting = new ExtensionSetting();
extensionSetting.extensions = new ExtensionFeedItem[] { appFeedItem };
campaignExtensionSetting.extensionSetting = extensionSetting;

Python

ap_url = 'https://play.google.com/store/apps/details?id=com.example.mobileapp'
app_feed_item = {
    'xsi_type': 'AppFeedItem',
    'appId': 'com.example.mobileapp',
    'appStore': 'GOOGLE_PLAY',
    'appLinkText': 'Install our mobile app!',
    'appFinalUrls': {
        'urls': [ap_url]
    }
}

campaign_extension_setting = {
    'campaignId': campaign_id,
    'extensionType': 'APP',
    'extensionSetting': {
        'extensions': [app_feed_item]
    }
}

$campaignExtensionSetting->setExtensionType(FeedType::APP);
$extensionSetting = new ExtensionSetting();
$extensionSetting->setExtensions([$appFeedItem]);
$campaignExtensionSetting->setExtensionSetting($extensionSetting);

Message extensions

Message extensions allow people to see your ad, click an icon, and contact you directly by text message. With one tap on your ad, people can contact you to book an appointment, get a quote, ask for information, or request a service. The following code snippet shows you how to do this using a MessageFeedItem:

Java

MessageFeedItem messageFeedItem = new MessageFeedItem();
messageFeedItem.setMessageBusinessName("Travel Here");
messageFeedItem.setMessageCountryCode("US");
messageFeedItem.setMessagePhoneNumber("212-565-0000");
messageFeedItem.setMessageText("I want to know more");
messageFeedItem.setMessageExtensionText("Ask us about travel.");

CampaignExtensionSetting campaignExtensionSetting = new CampaignExtensionSetting();
campaignExtensionSetting.setCampaignId(campaignId);
campaignExtensionSetting.setExtensionType(FeedType.MESSAGE);
ExtensionSetting extensionSetting = new ExtensionSetting();
extensionSetting.setExtensions(new ExtensionFeedItem[] {messageFeedItem});
campaignExtensionSetting.setExtensionSetting(extensionSetting);

C#

MessageFeedItem messageFeedItem = new MessageFeedItem();
messageFeedItem.messageBusinessName = "Travel Here";
messageFeedItem.messageCountryCode = "US";
messageFeedItem.messagePhoneNumber = "212-565-0000";
messageFeedItem.messageText = "I want to know more";
messageFeedItem.messageExtensionText = "Ask us about travel.";

CampaignExtensionSetting campaignExtensionSetting = new CampaignExtensionSetting();
campaignExtensionSetting.campaignId = campaignId;
campaignExtensionSetting.extensionType = FeedType.MESSAGE;
ExtensionSetting extensionSetting = new ExtensionSetting();
extensionSetting.extensions = new ExtensionFeedItem[] { messageFeedItem };
campaignExtensionSetting.extensionSetting = extensionSetting;

Python

message_feed_item = {
    'xsi_type': 'MessageFeedItem',
    'messageBusinessName': 'Travel Here',
    'messageCountryCode': 'US',
    'messagePhoneNumber': '212-565-0000',
    'messageText': 'I want to know more',
    'messageExtensionText': 'Ask us about travel.'
}

campaign_extension_setting = {
    'campaignId': campaign_id,
    'extensionType': 'MESSAGE',
    'extensionSetting': {
        'extensions': [message_feed_item]
    }
}

PHP

$messageFeedItem = new MessageFeedItem();
$messageFeedItem->setMessageBusinessName('Travel Here');
$messageFeedItem->setMessageCountryCode('US');
$messageFeedItem->setMessagePhoneNumber('212-565-0000');
$messageFeedItem->setMessageText('I want to know more');
$messageFeedItem->setMessageExtensionText('Ask us about travel.');

$campaignExtensionSetting = new CampaignExtensionSetting();
$campaignExtensionSetting->setCampaignId($campaignId);
$campaignExtensionSetting->setExtensionType(FeedType::MESSAGE);
$extensionSetting = new ExtensionSetting();
$extensionSetting->setExtensions([$messageFeedItem]);

    extensionType    => 'MESSAGE',
    extensionSetting => Google::Ads::AdWords::v201809::ExtensionSetting->new({
        extensions => [$message_feed_item]})});

Price extensions

A price extension is an extension type that provides users comparative details and pricing of your products or services. Price extensions allow you to enter a list of services, products, events, or other items, with a list of prices to display to the user.

Fully configurable and targetable like other extension types, price extensions show titles, descriptive information, and pricing details for at least three and as many as eight of your products or services.

Price extensions can be attached at the account, campaign, or ad group level.

The following code snippet shows how to create a price extension:

Java

// Create the price extension feed item.
PriceFeedItem priceFeedItem = new PriceFeedItem();
priceFeedItem.setPriceExtensionType(PriceExtensionType.SERVICES);

// Price qualifier is optional.
priceFeedItem.setPriceQualifier(PriceExtensionPriceQualifier.FROM);
priceFeedItem.setTrackingUrlTemplate("http://tracker.example.com/?u={lpurl}");
priceFeedItem.setLanguage("en");
FeedItemCampaignTargeting campaignTargeting = new FeedItemCampaignTargeting();
campaignTargeting.setTargetingCampaignId(campaignId);
priceFeedItem.setCampaignTargeting(campaignTargeting);
priceFeedItem.setScheduling(
    new FeedItemScheduling(
        new FeedItemSchedule[] {
          new FeedItemSchedule(DayOfWeek.SUNDAY, 10, MinuteOfHour.ZERO, 18, MinuteOfHour.ZERO),
          new FeedItemSchedule(DayOfWeek.SATURDAY, 10, MinuteOfHour.ZERO, 22, MinuteOfHour.ZERO)
        }));

// To create a price extension, at least three table rows are needed.
List<PriceTableRow> priceTableRows = new ArrayList<>();
String currencyCode = "USD";
priceTableRows.add(
    createPriceTableRow(
        "Scrubs",

Note: To avoid hitting account limits on the number of feed items, update prices in price extensions with SET operations instead of creating new PriceFeedItem objects.

Promotion extensions

Promotion extensions allow you to highlight sales and other promotions that let users see how they can save by buying now. There are many fields that let you customize exactly what appears in the extension, but the required ones are:

• promotionTarget - The text that appears on the ad when the extension is shown.

• percentOff or moneyAmountOff - One of these is required. They show the user how big the discount is.

  • percentOff takes a value in micros, where 1 million micros represents 1%, and is shown as a percentage when rendered. For example, the value 10000000 will render as "10%".
  • moneyAmountOff is also in micros. It requires both a currency and an amount of money.

• finalUrls - The URL targets for your landing page if someone clicks on the extension.

Optional fields:

• occasion - For example, NEW_YEARS or HALLOWEEN.

  • When using occasion without using extension setting services, make sure the values exactly match the documented enum values for PromotionFeedItem.

• discountModifier - Allows you to add "up to" verbiage to the promotion, in case you have variable promotion rates.

  • When using discountModifier without using extension setting services, make sure the values exactly match the documented enum values for PromotionFeedItem.

• promotionCode - For your users to enter to get the discount.

• ordersOverAmount - To indicate a minimum spend before the user qualifies for the promotion.

  • Note that only one promotionCode or ordersOverAmount is allowed per PromotionFeedItem.

• promotionStart and promotionEnd - Ensures that the extension only shows during the promotion period. These expect a datetime format, though only midnight is allowed. So for example, you can set promotionStart to '20180601 000000' and promotionEnd to '20180701 000000' for a June-only promotion.

  • You can clear these fields by setting the special value: '00000101 000000'.

• language - Provides a language for your promotion by inputting a language code. This defaults to English.

For details on the rest of the fields, check out the PromotionFeedItem docs.

Here's an example code snippet showing how to create a promotion extension:

Java

PromotionFeedItem promotionFeedItem = new PromotionFeedItem();
promotionFeedItem.setLanguage("en");
promotionFeedItem.setPromotionTarget("Wool Socks");
promotionFeedItem.setPercentOff(10_000_000L);
promotionFeedItem.setPromotionCode("WinterSocksDeal");
UrlList finalUrlsList = new UrlList();
finalUrlsList.setUrls(new String[] {"http://www.example.com/socks"});
promotionFeedItem.setFinalUrls(finalUrlsList);

CampaignExtensionSetting campaignExtensionSetting = new CampaignExtensionSetting();
campaignExtensionSetting.setCampaignId(campaignId);

ExtensionSetting extensionSetting = new ExtensionSetting();

Updating ad extensions

Suppose you decided to change your restaurant's happy hours on Saturday to 5pm to 10pm.

Note: You can use either the ADD or SET operator here, since the two operators are equivalent in extension setting services.

The first step is to retrieve the list of existing settings:

Java

CampaignExtensionSettingServiceInterface campaignExtensionSettingService =
    adWordsServices.get(session, CampaignExtensionSettingServiceInterface.class);
Selector selector =
    new SelectorBuilder()
        .fields(
            CampaignExtensionSettingField.CampaignId,
            CampaignExtensionSettingField.ExtensionType,
            CampaignExtensionSettingField.Extensions)
        .equals(CampaignExtensionSettingField.CampaignId, Long.toString(campaignId))
        .equals(CampaignExtensionSettingField.ExtensionType, FeedType.SITELINK.getValue())
        .build();

CampaignExtensionSettingPage page = campaignExtensionSettingService.get(selector);

C#

CampaignExtensionSettingService campaignExtensionSettingService =
    (CampaignExtensionSettingService) user.GetService(
        AdWordsService.v201809.CampaignExtensionSettingService);

Selector selector = new Selector() {
  fields = new string[] {
    CampaignExtensionSetting.Fields.CampaignId,
    CampaignExtensionSetting.Fields.ExtensionType,
    ExtensionSetting.Fields.Extensions
  },
  predicates = new Predicate[] {
    Predicate.Equals(CampaignExtensionSetting.Fields.CampaignId, campaignId),
    Predicate.Equals(CampaignExtensionSetting.Fields.ExtensionType,
        FeedType.SITELINK.ToString()),
  },
  paging = Paging.Default
};

CampaignExtensionSettingPage page = campaignExtensionSettingService.get(selector);

Python

campaign_extension_setting_service = client.GetService(
    'CampaignExtensionSettingService', 'v201809')

selector = {
    'fields': ['CampaignId', 'ExtensionType', 'Extensions'],

);

$page = $campaignExtensionSettingService->get($selector);

Next, update the desired sitelink:

CampaignExtensionSetting campaignExtensionSetting = page.getEntries(0);
for (ExtensionFeedItem extensionFeedItem :
    campaignExtensionSetting.getExtensionSetting().getExtensions()) {
  SitelinkFeedItem sitelinkFeedItem = (SitelinkFeedItem) extensionFeedItem;

    for (FeedItemSchedule feedItemSchedule :
        sitelinkFeedItem.getScheduling().getFeedItemSchedules()) {
      if (DayOfWeek.FRIDAY.equals(feedItemSchedule.getDayOfWeek())) {
        feedItemSchedule.setStartHour(17);
        feedItemSchedule.setStartMinute(MinuteOfHour.ZERO);
        feedItemSchedule.setEndHour(22);
        feedItemSchedule.setEndMinute(MinuteOfHour.ZERO);
      }
    }
  }
}

C#

CampaignExtensionSetting campaignExtensionSetting = page.entries[0];
foreach (ExtensionFeedItem extensionFeedItem in
    campaignExtensionSetting.extensionSetting.extensions) {
  SitelinkFeedItem sitelinkFeedItem = (SitelinkFeedItem) extensionFeedItem;
  if (sitelinkFeedItem.sitelinkText == "Happy hours") {
    foreach (FeedItemSchedule feedItemSchedule in sitelinkFeedItem.scheduling) {
      if (feedItemSchedule.dayOfWeek == DayOfWeek.FRIDAY) {
        feedItemSchedule.startHour = 17;
        feedItemSchedule.startMinute = MinuteOfHour.ZERO;
        feedItemSchedule.endHour = 22;
        feedItemSchedule.endMinute = MinuteOfHour.ZERO;
      }
    }
  }
}

Python

campaign_extension_setting = page['entries'][0]
extensions = campaign_extension_setting['extensionSetting']['extensions']

for extension_feed_item in extensions:
  if 'Happy hours' == extension_feed_item['sitelinkText']:
    schedules = extension_feed_item['scheduling']['feedItemSchedules']
    for feed_item_schedule in schedules:
      if feed_item_schedule['dayOfWeek'] == 'FRIDAY':
        feed_item_schedule['startHour'] = 17
        feed_item_schedule['startMinute'] = 'ZERO'
        feed_item_schedule['endHour'] = 22
        feed_item_schedule['endMinute'] = 'ZERO'

            if (DayOfWeek::FRIDAY === $feedItemSchedule->getDayOfWeek()) {
                $feedItemSchedule->setStartHour(17);
                $feedItemSchedule->setStartMinute(MinuteOfHour::ZERO);
                $feedItemSchedule->setEndHour(22);
                $feedItemSchedule->setEndMinute(MinuteOfHour::ZERO);
            }
        }
    }
}

        $feed_item_schedule->set_endMinute('ZERO');
      }
    }
  }
}

extensions.each do |sitelink_feed_item|
  if sitelink_feed_item[:sitelink_text] == 'Happy hours'
    schedules = sitelink_feed_item[:scheduling][:feed_item_schedules]
    schedules.each do |feed_item_schedule|
      if(feed_item_schedule[:day_of_week] == 'FRIDAY')
        feed_item_schedule[:start_hour] = 17
        feed_item_schedule[:start_minute] = 'ZERO'
        feed_item_schedule[:end_hour] = 22
        feed_item_schedule[:end_minute] = 'ZERO'
      end
    end
  end
end

Finally, send the modified campaignExtensionSetting to the server.

Java

CampaignExtensionSettingOperation operation = new CampaignExtensionSettingOperation();
operation.setOperator(Operator.SET);
operation.setOperand(campaignExtensionSetting);

C#

CampaignExtensionSettingOperation operation = new CampaignExtensionSettingOperation();
operation.@operator = Operator.SET;
operation.operand = campaignExtensionSetting;

Python

operations = [{
    'operator': 'SET',
    'operand': campaign_extension_setting
}]

PHP

$operation = new CampaignExtensionSettingOperation();
$operation->setOperator(Operator::SET);
$operation->setOperand($campaignExtensionSetting);

Perl

my $operation =
  Google::Ads::AdWords::v201809::CampaignExtensionSettingOperation->new({
    operator => 'ADD',
    operand  => $campaign_extension_setting
  });

Ruby

operation = {
  :operator => 'SET',
  :operand => campaign_extension_setting
}

To prevent the new settings from overwriting the old settings, remember to send back all feed items, even if you're modifying just one item.

Note: Any modifications made to the attributes of the ExtensionFeedItem will be reflected in all extension settings using that ExtensionFeedItem.

Removing ad extensions

Behind the scenes, the extension setting services are still using feeds to control your ad extensions. When you create a new extension setting, the service creates feed items for you in the appropriate feed and associates them with the given campaign, ad group, or account, depending on which service you used.

Similarly, when you remove an ExtensionFeedItem from an extension setting or remove the extension setting altogether, the service removes the association between the feed items and the attached entity, but it does not remove the feed items because they may be associated with another entity.

There are two ways to remove the association between a feed item and an entity:

1. You can remove the entire extension setting with a REMOVE operator. This will remove the association between the entity and all feed items in the extension setting.
2. You can remove individual ExtensionFeedItems within the extension setting, which you can do by specifying a new set of ExtensionFeedItems that does not contain the one you want to remove.

In both cases, the underlying feed items are not removed. Therefore, if the feed items are no longer associated with any other entities, you should consider deleting the feed items, which will free up space and allow you to generate new extensions in the future. Alternatively, you can reuse the feed items in other extension settings.

If you don't either remove or reuse feed items created from the extension setting services when you remove the extensions, these feed items will accrue over time and eventually you may reach the limit on the number of feed items you can have in your account.

Deleting feed items

If you want to delete the underlying feed items after you disassociate them from an entity, you can just grab the feedId and feedItemId from the extension you delete, and delete the corresponding FeedItem.

Java

CampaignExtensionSettingServiceInterface campaignExtensionSettingService =
    adWordsServices.get(session, CampaignExtensionSettingServiceInterface.class);
CampaignExtensionSettingOperation extensionSettingOperation =
    new CampaignExtensionSettingOperation();
extensionSettingOperation.setOperator(Operator.REMOVE);
extensionSettingOperation.setOperand(campaignExtensionSetting);

campaignExtensionSettingService.mutate(
    new CampaignExtensionSettingOperation[] {extensionSettingOperation});

FeedItemServiceInterface feedItemService =
    adWordsServices.get(session, FeedItemServiceInterface.class);
List<FeedItemOperation> feedItemOperations = new ArrayList<>();
for (ExtensionFeedItem extensionFeedItem :
    campaignExtensionSetting.getExtensionSetting().getExtensions()) {
  FeedItemOperation feedItemOperation = new FeedItemOperation();
  feedItemOperation.setOperator(Operator.REMOVE);

  FeedItem feedItem = new FeedItem();
  feedItem.setFeedId(extensionFeedItem.getFeedId());
  feedItem.setFeedItemId(extensionFeedItem.getFeedItemId());
  feedItemOperation.setOperand(feedItem);
  feedItemOperations.add(feedItemOperation);
}

feedItemService.mutate(
    feedItemOperations.toArray(new FeedItemOperation[feedItemOperations.size()]));

C#

CampaignExtensionSettingService campaignExtensionSettingService =
    (CampaignExtensionSettingService) user.GetService(
        AdWordsService.v201809.CampaignExtensionSettingService);

CampaignExtensionSettingOperation extensionSettingOperation =
    new CampaignExtensionSettingOperation();
extensionSettingOperation.@operator = Operator.REMOVE;
extensionSettingOperation.operand = campaignExtensionSetting;

campaignExtensionSettingService.mutate(
    new CampaignExtensionSettingOperation[] { extensionSettingOperation });

FeedItemService feedItemService = (FeedItemService) user.GetService(
    AdWordsService.v201809.FeedItemService);

List<FeedItemOperation> feedItemOperations = new List<FeedItemOperation>();
foreach (ExtensionFeedItem extensionFeedItem in
    campaignExtensionSetting.extensionSetting.extensions) {
  FeedItemOperation feedItemOperation = new FeedItemOperation();
  feedItemOperation.@operator = Operator.REMOVE;

  FeedItem feedItem = new FeedItem();
  feedItem.feedId = extensionFeedItem.feedId;
  feedItem.feedItemId = extensionFeedItem.feedItemId;
  feedItemOperation.operand = feedItem;
  feedItemOperations.Add(feedItemOperation);
}

feedItemService.mutate(feedItemOperations.ToArray());

Python

  campaign_extension_setting_service = client.GetService(
      'CampaignExtensionSettingService', 'v201809')
  feed_item_service = client.GetService('FeedItemService', 'v201809')
  operations = [{

          'feedItemId': extension_feed_item['feedItemId']
      }
  } for extension_feed_item in extensions]

  feed_item_service.mutate(operations)

The first REMOVE, on the CampaignExtensionSettingService, removes the association between that extension and the campaign. The second REMOVE, on the FeedItemService, removes the underlying feed items, freeing up space so that you can use new extensions in the future.

Reusing feed items

You can associate the same feed item with multiple entities. For example, if you want the same sitelinks to appear on multiple campaigns, you can associate each campaign with the same set of feed items.

Similarly, after removing an ad extension from one entity, you can associate the underlying feed item with a different entity by capturing the feedItemId from the response.

For example, if you have the old feedItemId from a previously removed extension setting stored in a variable storedFeedItemId, you can reuse it by populating only the feedItemId on the SitelinkFeedItem:

Java

SitelinkFeedItem sitelinkFeedItem = new SitelinkFeedItem();
sitelinkFeedItem.setFeedItemId(storedFeedItemId);

CampaignExtensionSetting campaignExtensionSetting = new CampaignExtensionSetting();
campaignExtensionSetting.setCampaignId(campaignId);
campaignExtensionSetting.setExtensionType(FeedType.SITELINK);
ExtensionSetting extensionSetting = new ExtensionSetting();
extensionSetting.setExtensions(new ExtensionFeedItem[] {sitelinkFeedItem});
campaignExtensionSetting.setExtensionSetting(extensionSetting);

C#

SitelinkFeedItem sitelinkFeedItem = new SitelinkFeedItem();
sitelinkFeedItem.feedItemId = storedFeedItemId;

CampaignExtensionSetting campaignExtensionSetting = new CampaignExtensionSetting();
campaignExtensionSetting.campaignId = campaignId;
campaignExtensionSetting.extensionType = FeedType.SITELINK;
ExtensionSetting extensionSetting = new ExtensionSetting();
extensionSetting.extensions = new ExtensionFeedItem[] { sitelinkFeedItem };
campaignExtensionSetting.extensionSetting = extensionSetting;

Python

site_link_feed_item = {
    'xsi_type': 'SitelinkFeedItem',
    'feedItemId': stored_feed_item_id
}

campaign_extension_setting = {
    'campaignId': campaign_id,
    'extensionType': 'SITELINK',
    'extensionSetting': {
        'extensions': [site_link_feed_item]
    }
}

PHP

$sitelinkFeedItem = new SitelinkFeedItem();
$sitelinkFeedItem->setFeedItemId($storedFeedItemId);

$campaignExtensionSetting = new CampaignExtensionSetting();
$campaignExtensionSetting->setCampaignId($campaignId);
$campaignExtensionSetting->setExtensionType(FeedType::SITELINK);
$extensionSetting = new ExtensionSetting();
$extensionSetting->setExtensions([$sitelinkFeedItem]);
$campaignExtensionSetting->setExtensionSetting($extensionSetting);

Perl

my $sitelink_feed_item = Google::Ads::AdWords::v201809::SitelinkFeedItem->new(
  {
    feedItemId => $stored_feed_item_id
  });

my $campaign_extension_setting =
  Google::Ads::AdWords::v201809::CampaignExtensionSetting->new({
    campaignId       => $campaign_id,
    extensionType    => 'SITELINK',
    extensionSetting => Google::Ads::AdWords::v201809::ExtensionSetting->new({
        extensions => [$sitelink_feed_item]})});

Ruby

sitelink_feed_item = {
  :xsi_type => 'SitelinkFeedItem',
  :feed_item_id => stored_feed_item_id
}
campaign_extension_setting = {
  :campaign_id => campaign_id,
  :extension_type => 'SITELINK',
  :extension_setting => {
    :extensions => [sitelink_feed_item]
  }
}

Targeting options for extensions

In addition to using an ExtensionSetting to target an extension at the customer, campaign, or ad group levels, you can also set targeting options on an individual ExtensionFeedItem by setting the campaignTargeting, adGroupTargeting, keywordTargeting, or geoTargeting attributes.

These targeting options will be combined with the ExtensionSetting properties to select which extension feed items will be used for a given impression.

For example, let's say you create a SitelinkFeedItem with the following targeting options:

• adGroupTargeting.TargetingAdGroupId = 12345
• keywordTargeting.id = 7890

In addition, you set the AdGroupExtensionSetting's platform restriction to MOBILE.

When serving impressions for this ad group, Google Ads only serves sitelinks from the SitelinkFeedItem if the impression attributes satisfy the targeting options on both AdGroupExtensionSetting and SitelinkFeedItem objects.

Case	Impression attributes	Result
1	ad group ID 12345 keyword 7890 a desktop user	The SitelinkFeedItem will not be used because the platform (desktop) does not satisfy the targeting options on AdGroupExtensionSetting.
2	ad group ID 12345 keyword 8910 a mobile user.	The SitelinkFeedItem will not be used because the keyword (7890) does not satisfy targeting options on SitelinkFeedItem.
3	ad group ID 12345 keyword 7890 a mobile user.	The SitelinkFeedItem will be used because the attributes satisfy the targeting options on both AdGroupExtensionSetting and SitelinkFeedItem.

Track ad extension performance

Use the Placeholder report or Placeholder Feed Item report to track the performance of your ad extensions. To identify your ad extensions use the FeedItemId column.

Migrate ad extensions to extension setting services

The rest of this guide covers the pros and cons of extension setting services, to help you decide whether to start using them, or stay with feed services. It also describes how to migrate to the new services.

Extension setting services provide a simplified layer over the existing feed-based ad extensions. The new services:

• Support concrete types for all supported ad extensions.
• Provide a simplified API that allows you to manage ad extensions for a campaign or ad group.

Should I migrate?

Extension setting services cover all ad extension features currently available in the Google Ads UI. Most users will benefit from spending some time to rewrite their services and migrate their data to use the simplified extension setting services. The following sections will help you decide whether or not to migrate to the extension setting services.

When are extension setting services preferred?

If you simply need to add ad extensions to a campaign or ad group, set its device preference, or manage its schedule, then we recommend using extension setting services. An added benefit when using extension setting services is that unlike feed services, we maintain your feed's schema and data, so you won't have to keep up with the underlying feed structure.

When are legacy feed services preferred?

We recommend using the legacy feed services if you need to use one or more of the features listed below:

• Location extensions: Extension setting services do not include support for location extensions.
• Custom fields or matching functions: Extension setting services don't support custom fields in feeds, or writing custom matching functions.
• Multiple feeds: Extension setting services only support one feed per extension type that is managed by the system.

Migration steps

If you've only used feeds created in the Google Ads UI, you can use extension setting services immediately.

However, if you've created custom feeds with the API, you'll need to first perform the following steps:

1. Retrieve feed items in your custom feeds.
2. Identify feed items you want to keep.
3. Delete the CustomerFeed, CampaignFeed and AdGroupFeeds that use the feed items from the custom feeds.
4. Create CustomerExtensionSetting, CampaignExtensionSetting and AdGroupExtensionSettings that use the new ExtensionFeedItems.
5. (Optional) Delete feed items that are no longer in use.

The sections below focus on upgrading ad extensions at the campaign level, but the same process applies at the ad group level.

Retrieve feed items in your custom feeds

To retrieve feed items in your custom feeds, you must first identify all custom feeds you've created using the AdWords API, as follows:

Java

FeedServiceInterface feedService = adWordsServices.get(session, FeedServiceInterface.class);
String query = "SELECT Id, Name, Attributes WHERE Origin = 'USER' AND FeedStatus = 'ENABLED'";

List<Feed> feeds = new ArrayList<>();
int offset = 0;
FeedPage feedPage;

do {
  String pageQuery = String.format(query + " LIMIT %d, %d", offset, PAGE_SIZE);
  feedPage = feedService.query(pageQuery);
  if (feedPage.getEntries() != null) {
    feeds.addAll(Arrays.asList(feedPage.getEntries()));
  }
  offset += PAGE_SIZE;
} while (offset < feedPage.getTotalNumEntries());

return feeds;

C#

using (FeedService feedService =
    (FeedService) user.GetService(AdWordsService.v201809.FeedService))
{
    FeedPage page = feedService.query("SELECT Id, Name, Attributes where " +
        "Origin='USER' and FeedStatus='ENABLED'");
    return page.entries;
}

Python

feed_service = client.GetService('FeedService', 'v201809')

feeds = []
more_pages = True

selector = {
    'fields': ['Id', 'Name', 'Attributes'],
    'predicates': [
        {
            'field': 'Origin',
            'operator': 'EQUALS',
            'values': ['USER']
        },
        {
            'field': 'FeedStatus',
            'operator': 'EQUALS',
            'values': ['ENABLED']
        }
    ],
    'paging': {
        'startIndex': 0,
        'numberResults': PAGE_SIZE
    }
}

while more_pages:
  page = feed_service.get(selector)

  if 'entries' in page:
    feeds.extend(page['entries'])

  selector['paging']['startIndex'] += PAGE_SIZE
  more_pages = selector['paging']['startIndex'] < int(page['totalNumEntries'])

return feeds

PHP

$feedService = $adWordsServices->get($session, FeedService::class);

// Create paging controls.
$totalNumEntries = 0;
$offset = 0;
$query = 'SELECT Id, Name, Attributes WHERE Origin="USER" AND '
    . 'FeedStatus="ENABLED"';
$feeds = [];
do {
    $pageQuery =
        sprintf('%s LIMIT %d,%d', $query, $offset, self::PAGE_LIMIT);

    // Make the query request.
    $page = $feedService->query($pageQuery);

    if ($page->getEntries() !== null) {
        $totalNumEntries = $page->getTotalNumEntries();
        foreach ($page->getEntries() as $feed) {
            $feeds[] = $feed;
        }
    }
    // Advance the paging offset.
    $offset += self::PAGE_LIMIT;
} while ($offset < $totalNumEntries);

return $feeds;

Perl

my ($client) = @_;

my $query =
  "SELECT Id, Name, Attributes WHERE Origin = 'USER' AND " .
  "FeedStatus = 'ENABLED'";

# Paginate through results automatically, and retrieve the feeds.
my @feeds = Google::Ads::AdWords::Utilities::PageProcessor->new({
    client    => $client,
    service   => $client->FeedService(),
    query     => $query,
    page_size => PAGE_SIZE
  })->get_entries();

return \@feeds;

Ruby

def get_feeds(adwords)
  feed_srv = adwords.service(:FeedService, API_VERSION)
  query = "SELECT Id, Name, Attributes " +
      "WHERE Origin = 'USER' AND FeedStatus = 'ENABLED'"

  feeds = []
  offset = 0

  begin
    page_query = (query + " LIMIT %d, %d") % [offset, PAGE_SIZE]
    page = feed_srv.query(page_query)

    unless page[:entries].nil?
      feeds += page[:entries]
    end
    offset += PAGE_SIZE
  end while page[:total_num_entries] > offset

  return feeds
end

VB.NET

Using feedService As FeedService = DirectCast(
    user.GetService(
        AdWordsService.v201809.FeedService),
    FeedService)
    Dim page As FeedPage = feedService.query("SELECT Id, Name, Attributes where " &
                                             "Origin='USER' and FeedStatus='ENABLED'")
    Return page.entries
End Using

Next, retrieve feed items in these feeds. The example uses sitelinks, but the approach is similar for the other ad extensions.

Java

// Get the FeedItemService.
FeedItemServiceInterface feedItemService =
    adWordsServices.get(session, FeedItemServiceInterface.class);
String query = String.format(
    "SELECT FeedItemId, AttributeValues WHERE Status = 'ENABLED' AND FeedId = %d",
    feed.getId());

List<FeedItem> feedItems = new ArrayList<>();
int offset = 0;
FeedItemPage feedItemPage;

do {
  String pageQuery = String.format(query + " LIMIT %d, %d", offset, PAGE_SIZE);
  feedItemPage = feedItemService.query(pageQuery);
  if (feedItemPage.getEntries() != null) {
    feedItems.addAll(Arrays.asList(feedItemPage.getEntries()));
  }
  offset += PAGE_SIZE;
} while (offset < feedItemPage.getTotalNumEntries());

return feedItems;

C#

using (FeedItemService feedItemService =
    (FeedItemService) user.GetService(AdWordsService.v201809.FeedItemService))
{
    FeedItemPage page = feedItemService.query(string.Format(
        "Select FeedItemId, " +
        "AttributeValues  where Status = 'ENABLED' and FeedId = '{0}'", feedId));
    return page.entries;
}

Python

feed_item_service = client.GetService('FeedItemService', 'v201809')

feed_items = []
more_pages = True

selector = {
    'fields': ['FeedItemId', 'AttributeValues'],
    'predicates': [
        {
            'field': 'Status',
            'operator': 'EQUALS',
            'values': ['ENABLED']

To convert a FeedItem into a SitelinksFromFeed object, you must retrieve the FeedMapping for the feed, and then map each attribute into the corresponding object properties.

You can retrieve the FeedMapping as follows:

Java

private static Multimap<Long, Integer> getFeedMapping(AdWordsServicesInterface adWordsServices,
    AdWordsSession session, Feed feed, long placeholderType) throws RemoteException {
  // Get the FeedMappingService.
  FeedMappingServiceInterface feedMappingService =
      adWordsServices.get(session, FeedMappingServiceInterface.class);
  String query = String.format(
      "SELECT FeedMappingId, AttributeFieldMappings WHERE FeedId = %d and PlaceholderType = %d "
      + "AND Status = 'ENABLED'", feed.getId(), placeholderType);

  Multimap<Long, Integer> attributeMappings = HashMultimap.create();
  int offset = 0;
  FeedMappingPage feedMappingPage;

  do {
    String pageQuery = String.format(query + " LIMIT %d, %d", offset, PAGE_SIZE);
    feedMappingPage = feedMappingService.query(pageQuery);
    if (feedMappingPage.getEntries() != null) {
      // Normally, a feed attribute is mapped only to one field. However, you may map it to more
      // than one field if needed.
      for (FeedMapping feedMapping : feedMappingPage.getEntries()) {
        for (AttributeFieldMapping attributeMapping : feedMapping.getAttributeFieldMappings()) {
          attributeMappings.put(attributeMapping.getFeedAttributeId(),
              attributeMapping.getFieldId());
        }
      }
    }
    offset += PAGE_SIZE;
  } while (offset < feedMappingPage.getTotalNumEntries());

  return attributeMappings;
}

Identify feed items you want to keep

Identify the list of feed items associated with a campaign by retrieving the CampaignFeed associated with the campaign and parsing its matchingFunction. Since matching functions allow you to write a general-purpose expression tree, writing a parser for a general case is complex, and we won't cover it in this guide. We'll instead pick the simplest case, where a few feed items from a single feed have been associated with a campaign. This matching function takes the following form:

FEEDITEM_ID IN (FEEDITEM_ID_1, FEEDITEM_ID_2…)

Java

    feedItemIds.addAll(getFeedItemIdsFromArgument(campaignFeed.getMatchingFunction()));

Delete existing CampaignFeed

Before you add extension settings to a campaign, you must delete the campaign's existing CampaignFeed. This is required since AdWords supports only one CampaignFeed per extension type for a campaign. Deleting your manually-created CampaignFeed allows the CampaignExtensionSettingService to create a new system-managed CampaignFeed when you add extension settings.

Java

private static CampaignFeed deleteCampaignFeed(AdWordsServicesInterface adWordsServices,
    AdWordsSession session, CampaignFeed campaignFeed) throws RemoteException {
  // Get the CampaignFeedService.
  CampaignFeedServiceInterface campaignFeedService =
      adWordsServices.get(session, CampaignFeedServiceInterface.class);

  CampaignFeedOperation operation = new CampaignFeedOperation();
  operation.setOperand(campaignFeed);
  operation.setOperator(Operator.REMOVE);

  return campaignFeedService.mutate(new CampaignFeedOperation[] {operation}).getValue(0);
}

C#

private CampaignFeed DeleteCampaignFeed(AdWordsUser user, CampaignFeed campaignFeed)
{
    using (CampaignFeedService campaignFeedService =

    {
        CampaignFeedOperation operation = new CampaignFeedOperation()
        {
            operand = campaignFeed,
            @operator = Operator.REMOVE
        };

        CampaignFeed retval = campaignFeedService.mutate(new CampaignFeedOperation[]
        {
            operation
        }).value[0];
        return retval;
    }
}
