ショッピング比較サービス（CSS）では、CSS プログラムが利用可能な国で、販売者の代理として Google にショッピング広告を掲載できます。Content API を使用すると、CSS ドメインと CSS グループはラベルを使用して関連付けられたアカウントを整理できます。CSS ドメインは、ドメインに関連付けられている Merchant Center アカウントを一覧表示、ラベル付け、フィルタできます。CSS グループは、グループに関連付けられている CSS ドメインにラベルを付けて一覧表示できます。これらの Content API サービスは、ショッピング比較サービス センターで利用できる機能の一部に相当するプログラムを提供します。
Merchant Center アカウントは、CSS ドメインがショッピング広告を掲載する販売者です。CSS は、マルチクライアント アカウント（MCA）や個々の販売アカウントなど、さまざまな種類の Merchant Center アカウントに関連付けることができます。各 Merchant Center アカウントは、1 つの CSS ドメインにのみ関連付けることができます。Merchant Center アカウントのさまざまな種類について詳しくは、Comparison Shopping Service Center のアカウントの種類をご覧ください。
CSS ラベルの種類
CSS では、次の 2 種類のラベルを使用します。
手動ラベルは、CSS ドメインによって Merchant Center アカウントに、CSS グループによって CSS ドメインに作成、割り当てられます。
自動ラベルは、CSS Center によって自動的に作成され、Merchant Center アカウントに割り当てられます。自動ラベルはさまざまなタイプのアカウント指標で使用でき、重要なアカウントやアカウントの重要なアクティビティを特定するのに役立ちます。

The Content API\nallows CSS domains and CSS groups to organize their associated accounts using\nlabels. CSS domains can list, label, and filter the Merchant Center accounts\nassociated with the domain. CSS groups can label and list the CSS domains\naffiliated with the group. These Content API services provide programmatic\nequivalents to some of the features available in the [Comparison Shopping\nService Center](//support.google.com/merchants/answer/9773265).\n\nFor more information about CSSs, see\n[Comparison Shopping Services](//support.google.com/merchants/topic/9080307).\nFor information on working with labels in CSS Center, see\n[Use account labels in Comparison Shopping Service Center](//support.google.com/merchants/answer/9773369).\n\nCSS account types\n-----------------\n\nCSSs use the following three types of accounts:\n\n- *CSS groups* are the top-level accounts that can contain one or multiple CSS domains.\n- *CSS domains* are the accounts for the CSSs themselves, which place Shopping ads on behalf of merchants. Each CSS domain can only belong to one CSS group.\n- *Merchant Center accounts* are the merchants for which CSS domains place Shopping ads. CSSs can be associated with several different types of Merchant Center accounts, including multi-client accounts (MCAs) and individual merchant accounts. Each Merchant Center account can only be associated with one CSS domain. For more information about different types of Merchant Center accounts, see [Account types in Comparison Shopping Service Center](//support.google.com/merchants/answer/9772965).\n\nCSS label types\n---------------\n\nCSSs use two types of labels:\n\n- *Manual labels* are created and assigned to Merchant Center accounts by CSS domains, and to CSS domains by CSS groups.\n- *Automatic labels* are automatically created and assigned to Merchant Center accounts by CSS Center. Automatic labels are available for different types of account metrics and can help you identify important accounts and significant account activity.\n\nFor more information about label types, including the available automatic\nlabels, see\n[Use account labels in Comparison Shopping Service Center](//support.google.com/merchants/answer/9773369).\n\nContent API functionality and endpoints for CSSs\n------------------------------------------------\n\nThe Content API offers the following endpoints for CSSs:\n\n- [`accounts.labels`](/shopping-content/reference/rest/v2.1/accounts.labels): Allows you to create, retrieve, and modify labels to apply to CSS domain and Merchant Center accounts. For an example, see [Creating a label](#create-label).\n- [`accounts.updatelabels`](/shopping-content/reference/rest/v2.1/accounts/updatelabels): Allows you to apply labels to a single Merchant Center account. For an example, see [Applying a label to a Merchant Center account](#apply-label).\n- [`accounts.list`](/shopping-content/reference/rest/v2.1/accounts/list): Allows you to retrieve all the Merchant Center accounts associated with a CSS domain, including the labels applied to each account. You can also filter by label `id` to retrieve a subset of associated accounts. For an example, see [Using labels to filter Merchant Center accounts](#filter).\n- [`accounts.get`](/shopping-content/reference/rest/v2.1/accounts/get): Allows you to retrieve the labels applied to a single Merchant Center account.\n- [`csses`](/shopping-content/reference/rest/v2.1/csses): Allows you to view and manage the associations between labels and CSS domains. For an example, see [Applying a label to a CSS domain](#domain-label).\n\nWhen calling `accounts` endpoints as a CSS domain, be aware of the following\nrequirements:\n\n- CSS domains must provide their `cssId` instead of a `merchantId`.\n- CSS domains must provide a query parameter of `view=CSS`.\n- CSS domains must provide their associated Merchant Center account id as the `accountId`.\n\n| **Note:** Only CSS domain and CSS group accounts can use labels. Merchant Center accounts themselves do not have access to the label functionality.\n\nExample: Create a label\n-----------------------\n\nYou can use the `accounts.labels.create` method to create a new label. Labels\ncan be applied to CSS domains and Merchant Center accounts. However, labels for\nthe different account types are separate and cannot be used interchangeably. To\ncreate a domain-level label, which can be applied to Merchant Center accounts\nassociated with the domain, use the CSS domain ID as the `accountId` when\ncreating the label. To create a group-level label, which can be applied to CSS\ndomains affiliated with the group, use the CSS group ID as the `accountId` when\ncreating the label.\n\nThe following example demonstrates how to create a **domain-level** key-accounts\nlabel, which can then be applied to Merchant Center accounts associated with the\ndomain. To create the label, make a `POST` request using the following URL and\nrequest body: \n\n https://shoppingcontent.googleapis.com/content/v2.1/accounts/\u003cvar translate=\"no\"\u003e\u003cspan class=\"devsite-syntax-nt\"\u003eaccountId\u003c/span\u003e\u003c/var\u003e/labels\n\n {\n \"name\": \"key-accounts\",\n \"description\": \"All accounts with over a million products\"\n }\n\nExample: Apply a label to a Merchant Center account\n---------------------------------------------------\n\nYou can use the `accounts.updatelabels` method to assign labels to a Merchant\nCenter account associated with a CSS domain. The following example demonstrates\nhow to apply the **key-accounts** label created in the previous example to one\nof your most important Merchant Center accounts.\n| **Note:** You must use the `id` of the label, not the name, when applying a label to a Merchant Center account. The `id` is automatically assigned to the label and returned in the response when the label is created. You can also retrieve the label `id` by calling `accounts.labels.list`.\n\nTo apply the label, make a `POST` request using the following URL and request\nbody: \n\n https://shoppingcontent.googleapis.com/content/v2.1/\u003cvar translate=\"no\"\u003e\u003cspan class=\"devsite-syntax-nt\"\u003ecssId\u003c/span\u003e\u003c/var\u003e/accounts/\u003cvar translate=\"no\"\u003e\u003cspan class=\"devsite-syntax-nt\"\u003esubaccountId\u003c/span\u003e\u003c/var\u003e/updatelabels/\n\n {\n \"labelIds\": ['123'] // 'key-accounts'\n }\n\nExample: Use labels to filter Merchant Center accounts\n------------------------------------------------------\n\nAfter creating and applying labels to the Merchant Center accounts associated\nwith a CSS domain, you can use the `accounts.list` method and pass the label\nquery parameter in your request to return only the accounts with that label. The\nfollowing example demonstrates how to filter the Merchant Center accounts\nassociated with a CSS domain, using the `id` (`123`) of the **key-accounts**\nlabel created in the [Creating a label](#create-label) example. To retrieve the\naccoungs, make a `GET` request using the following URL: \n\n https://shoppingcontent.googleapis.com/content/v2.1/\u003cvar translate=\"no\"\u003e\u003cspan class=\"devsite-syntax-nt\"\u003ecssId\u003c/span\u003e\u003c/var\u003e/accounts?view=CSS&label=123\n\nNo request body is needed.\n\nExample: Apply a label to a CSS domain\n--------------------------------------\n\nYou can also use the `csses.updatelabels` method to assign labels to a CSS\ndomain affiliated with a CSS group. The following example demonstrates how to\napply a **key-domains** group-level label created using the\n`accounts.labels.create` method to one of your most important CSS domain\naccounts. Keep in mind that labels for CSS domains and Merchant Center accounts\nare separate. Group-level labels must be created using a CSS group ID as its\n`accountId`.\n| **Note:** You must use the `id` of the label, not the name, when applying a label to a CSS domain. The `id` is automatically assigned to the label and returned in the response when the label is created. You can also retrieve the label `id` by calling `accounts.labels.list`.\n\nTo apply the label, make a `POST` request using the following URL and request\nbody: \n\n https://shoppingcontent.googleapis.com/content/v2.1/\u003cvar translate=\"no\"\u003e\u003cspan class=\"devsite-syntax-nt\"\u003ecssGroupId\u003c/span\u003e\u003c/var\u003e/csses/\u003cvar translate=\"no\"\u003e\u003cspan class=\"devsite-syntax-nt\"\u003ecssDomainId\u003c/span\u003e\u003c/var\u003e/updatelabels/\n\n {\n \"labelIds\": ['456'] // 'key-domains'\n }"]]
