DEPRECATED: Remove an extension setting

Extension setting services use feeds to control ad extensions. ExtensionFeedItem is a wrapper over a FeedItem that handles much of the feed mechanics for you. Still, there are some cleanup that are required when removing an extension setting.

A functional extension setting is made up of both some set of extension feed items and either one CustomerExtensionSetting, CampaignExtensionSetting, or AdGroupExtensionSetting. You can delete the extension setting, which will remove the association between the extension feed items and that resource, but the extension feed items will still exist and can be reused with other extension settings in the future. You can also update an extension setting to use a different set of extension feed items, but again unused feed items will continue to exist.

To remove extension feed items that are no longer associated with any extension settings, make a followup call to the ExtensionFeedItemService.

Remove the entire extension setting

The example below assumes we want to remove both the extension setting and extension feed item that were created earlier. Removing the extension setting doesn't automatically remove the extension feed items, so that must be done in a separate step. In our example, all removal operations are sent using a multiresource mutate request, GoogleAdsService.Mutate(), to ensure they're executed as one set of operations. The set of operations will all succeed if no operation fails or all fail if any single operation fails. To execute the operations for extension settings and extension feed items independently, set the partialFailure attribute to true. See Mutating Resources for more detailed information on mutate operation semantics.

Remove an extension feed item from an existing setting

Alternatively, if you want to keep the extension setting but change which extension feed items it uses, you can update the extension setting and set the full set of extension settings to use. Remember that this doesn't completely remove the extension feed item; it just disassociates it from this extension setting.

Java

private void runExample(
    GoogleAdsClient googleAdsClient, long customerId, long campaignId, List<Long> feedItemIds) {
  // Converts the feed item IDs into resource names.
  List<String> feedItemResourceNames =
      feedItemIds.stream()
          .map(id -> ResourceNames.extensionFeedItem(customerId, id))
          .collect(Collectors.toList());

  // Creates a CampaignExtensionSetting object to update.
  CampaignExtensionSetting campaignExtensionSetting =
      CampaignExtensionSetting.newBuilder()
          .setResourceName(
              ResourceNames.campaignExtensionSetting(
                  customerId, campaignId, ExtensionType.SITELINK))
          .addAllExtensionFeedItems(feedItemResourceNames)
          .build();

  // Creates an operation to update CampaignExtensionSetting.
  CampaignExtensionSettingOperation operation =
      CampaignExtensionSettingOperation.newBuilder()
          .setUpdate(campaignExtensionSetting)
          .setUpdateMask(FieldMasks.allSetFieldsOf(campaignExtensionSetting))
          .build();

  // Connects to the API.
  try (CampaignExtensionSettingServiceClient client =
      googleAdsClient.getLatestVersion().createCampaignExtensionSettingServiceClient()) {
    // Issues the mutate request.
    MutateCampaignExtensionSettingsResponse response =
        client.mutateCampaignExtensionSettings(
            String.valueOf(customerId), ImmutableList.of(operation));

    // Prints some debugging information.
    String resourceName = response.getResults(0).getResourceName();
    System.out.printf(
        "Updated a campaign extension setting with resource name: '%s'.%n", resourceName);
