管理本地 Feed 合作伙伴关系 (LFP) 提供商

零售商可以通过本地 Feed 合作伙伴关系计划参与本地商品目录广告和非付费本地商品详情，而无需创建自己的主要 Feed 和本地商品目录 Feed。可信数据提供商可以代表零售商向 Google 提供销售数据或商品目录数据。

前提条件

如需使用本部分中的 API 方法，请先建立本地商品目录广告 (LIA) 或非付费本地商品详情 (FLL) 计划。如需了解详情，请参阅管理全渠道设置。

查找可用的 LFP 提供商

如需检索某个国家/地区中的所有可用 LFP 提供商，请使用 lfpProviders.findLfpProviders。

POST
https://merchantapi.googleapis.com/accounts/v1/accounts/{ACCOUNT_ID}/omnichannelSettings/{REGION_CODE}/lfpProviders:find

    }
  ],

}

以下是一个代码示例：

package shopping.merchant.samples.accounts.v1;

// [START merchantapi_find_lfp_providers]

/** This class demonstrates how to get the Lfp Providers for a given Merchant Center account */
public class FindLfpProvidersSample {

  public static void findLfpProviders(Config config, String regionCode)
      throws Exception {

    // Obtains OAuth token based on the user's configuration.
    GoogleCredentials credential = new Authenticator().authenticate();

    // Creates service settings using the retrieved credentials.
    LfpProvidersServiceSettings lfpProvidersServiceSettings =
        LfpProvidersServiceSettings.newBuilder()
            .setCredentialsProvider(FixedCredentialsProvider.create(credential))
            .build();

    // Gets the account ID from the config file.
    String accountId = config.getAccountId().toString();
    // Creates parent to identify the omnichannelSetting from which to list all Lfp Providers.
    String parent =
        OmnichannelSettingName.newBuilder()
            .setAccount(accountId)
            .setOmnichannelSetting(regionCode)
            .build()
            .toString();

    // Calls the API and catches and prints any network failures/errors.
    try (LfpProvidersServiceClient lfpProvidersServiceClient =
        LfpProvidersServiceClient.create(lfpProvidersServiceSettings)) {
      FindLfpProvidersRequest request =
          FindLfpProvidersRequest.newBuilder().setParent(parent).build();

      System.out.println("Sending find LFP providers request:");
      FindLfpProvidersPagedResponse response = lfpProvidersServiceClient.findLfpProviders(request);

      int count = 0;

      // Iterates over all the entries in the response.
      for (LfpProvider lfpProvider : response.iterateAll()) {
        System.out.println(lfpProvider);
        count++;
      }
      System.out.println(String.format("The following count of elements were returned: %d", count));
    } catch (Exception e) {
      System.out.println("An error has occurred: ");
      System.out.println(e);
    }
  }

  public static void main(String[] args) throws Exception {
    Config config = Config.load();

    // The country you're targeting at.
    String regionCode = "{REGION_CODE}";

    findLfpProviders(config, regionCode);
  }
}
// [END merchantapi_find_lfp_providers]

如需建立 LFP 合作伙伴关系，请使用 lfpProviders.LinkLfpProvider：

POST
https://merchantapi.googleapis.com/accounts/v1/accounts/{ACCOUNT_ID}/omnichannelSettings/{REGION_CODE}/lfpProviders/{LFP_PROVIDER}:linkLfpProvider
{
  "externalAccountId": "{EXTERNAL_ACCOUNT_ID}",
}

替换以下内容：

  • {ACCOUNT_ID}：您的 Merchant Center 账号的唯一标识符
  • {LFP_PROVIDER}：上一步中返回的 LFP 提供程序 ID。例如，对于 LFP 提供程序 1，该值为 12345。
  • {EXTERNAL_ACCOUNT_ID}：LFP 提供商通过该外部账号 ID 识别商家。

以下代码示例展示了如何关联到 LFP 提供程序：

package shopping.merchant.samples.accounts.v1;

// [START merchantapi_link_lfp_provider]
import com.google.api.gax.core.FixedCredentialsProvider;
import com.google.auth.oauth2.GoogleCredentials;

import com.google.shopping.merchant.accounts.v1.LfpProvidersServiceSettings;
import com.google.shopping.merchant.accounts.v1.LinkLfpProviderRequest;
import shopping.merchant.samples.utils.Authenticator;

/** This class demonstrates how to link the Lfp Providers for a given Merchant Center account */
public class LinkLfpProviderSample {

  public static void linkLfpProvider(String lfpProviderName, String externalAccountId)
      throws Exception {

    // Obtains OAuth token based on the user's configuration.
    GoogleCredentials credential = new Authenticator().authenticate();

    // Creates service settings using the retrieved credentials.
    LfpProvidersServiceSettings lfpProvidersServiceSettings =
        LfpProvidersServiceSettings.newBuilder()
            .setCredentialsProvider(FixedCredentialsProvider.create(credential))
            .build();

    // Calls the API and catches and prints any network failures/errors.
    try (LfpProvidersServiceClient lfpProvidersServiceClient =
        LfpProvidersServiceClient.create(lfpProvidersServiceSettings)) {
      LinkLfpProviderRequest request =
          LinkLfpProviderRequest.newBuilder()
              .setName(lfpProviderName)
              .setExternalAccountId(externalAccountId)
              .build();

      System.out.println("Sending link lfp provider request:");
      // Empty response returned on success.
      lfpProvidersServiceClient.linkLfpProvider(request);
      System.out.println(String.format("Successfully linked to LFP provider: %s", lfpProviderName));
    } catch (Exception e) {
      System.out.println("An error has occurred: ");
      System.out.println(e);
    }
  }

  public static void main(String[] args) throws Exception {
    // The name of the lfp provider you want to link, returned from `lfpProviders.findLfpProviders`.
    // It's of the form
    // "accounts/{account_id}/omnichannelSettings/{omnichannel_settings}/lfpProviders/{lfp_provider}".
    String lfpProviderName = "{LFP_PROVIDER_NAME}";
    // External account ID by which this merchant is known to the LFP provider.
    String externalAccountId = "{EXTERNAL_ACCOUNT_ID}";

    linkLfpProvider(lfpProviderName, externalAccountId);
  }
}
// [END merchantapi_link_lfp_provider]

``` You can check your LFP status by calling `omnichannelSettings.get` and
checking the `LfpLink` field.
