Google 포토 API를 사용하려면 Google API 콘솔을 사용하여 필요한 포토 API를 사용 설정하고 OAuth 2.0 클라이언트 ID를 설정하여 프로젝트를 구성합니다.
애플리케이션이 Google 포토 사용자를 대신하여 Google 포토와 상호작용합니다. 예를 들어 사용자의 Google 포토 라이브러리에서 앨범을 만들거나 사용자의 Google 포토 계정에 미디어 항목을 업로드하는 경우 사용자는 OAuth 2.0 프로토콜을 사용하여 이러한 API 요청을 승인합니다.
OAuth 2.0 클라이언트 ID를 사용하면 애플리케이션 사용자가 로그인하고 인증하여 포토 API를 사용할 수 있습니다. Photos API는 서비스 계정을 지원하지 않습니다. 이 API를 사용하려면 사용자가 유효한 Google 계정에 로그인해야 합니다.
Google 포토 API를 통해 만든 리소스는 만들 때 사용한 원래 클라이언트 ID를 사용하여만 액세스하거나 수정할 수 있습니다. 예를 들어 Picker API에서 특정 클라이언트 ID로 session를 만들고 나중에 앱에서 해당 클라이언트 ID를 변경하면 앱은 이전 클라이언트 ID로 만든 모든 API 리소스에 액세스할 수 없게 됩니다.
신중하게 계획하고 사용 중인 포토 API에 적합한 클라이언트 ID 유형을 선택하세요. 액세스 문제를 방지하기 위해 절대적으로 필요한 경우에만 클라이언트 ID를 변경하세요.

Note that user sign-in via a valid Google Account is necessary. Applications must be verified by Google before public launch, and client ID changes can cause access issues to previously created resources.\n"],null,["# Configure your app\n\nTo start using the Google Photos APIs, configure your project by enabling the Photos\nAPIs you need using the Google API Console and setting up an OAuth 2.0 client ID.\n\nYour application interacts with Google Photos on behalf of a\nGoogle Photos user. For example, when you create albums in a user's\nGoogle Photos library or upload media items to a user's\nGoogle Photos account, the user authorizes these API requests using the\n[OAuth 2.0](/identity/protocols/OAuth2) protocol.\n\nThe OAuth 2.0 client ID allows your application users to sign in, authenticate,\nand thereby use the Photos APIs. The Photos APIs don't support\nservice accounts; to use these APIs, users must be signed in to a valid Google\nAccount.\n\nConfigure your app\n------------------\n\nFirst enable the API, then request an OAuth 2.0 client ID.\n\n### Enable the API\n\nBefore you can use the Photos APIs, you must enable them in your project.\n\n1. Go to the [Google API Console](https://console.developers.google.com/apis/library).\n2. From the menu bar, select a project or create a new project.\n3. To open one of the Google Photos APIs, from the Navigation menu, select **APIs \\& Services \\\u003e Library**.\n4. Search for \"Photos\". Select one or more of the Photos APIs and click **Enable**.\n\n| **Note:** When searching Google APIs, you may also see the \"Google Picker API\", which is different from the Google Photos Picker API.\n\n### Request an OAuth 2.0 client ID\n\nFollow these steps to request an OAuth client ID and configure it for your\napplication. This example uses an application where the entire OAuth flow is\nhandled server-side, such as the one in our samples. The setup process may vary\nfor other [implementation scenarios](/identity/protocols/OAuth2).\n\n1. Go to the [Google API Console](https://console.developers.google.com/apis/library) and select your project.\n2. From the menu, select **APIs \\& Services \\\u003e Credentials**.\n3. On the **Credentials** page, click **Create Credentials \\\u003e OAuth client ID**.\n\n | **Note:** If you're setting up a new project, you may be prompted to configure your project's consent screen.\n4. Select your **Application type** . In this example, the application type is\n **Web application**.\n\n5. Register the origins from which your app is allowed to access the Google\n APIs as follows:\n\n 1. To identify the client ID, enter a name.\n 2. In the **Authorized JavaScript origins** field, enter the origin for\n your app. This field doesn't allow wildcards.\n\n You can enter multiple origins to allow your app to run on different\n protocols, domains, or subdomains. The URLs you enter are allowed to\n start an OAuth request.\n\n The following example shows a local development URL (our samples use\n `localhost:8080`) and a production URL. \n\n http://localhost:8080\n https://myproductionurl.example.com\n\n 3. The **Authorized redirect URI** field is the endpoint that receives\n responses from the OAuth 2.0 server. Typically, this includes your\n development environment and points to a path in your application.\n\n http://localhost:8080/auth/google/callback\n https://myproductionurl.example.com/auth/google/callback\n\n 4. Click **Create**.\n\n\u003c!-- --\u003e\n\n6. From the resulting OAuth client dialog, copy the following:\n\n - Client ID\n - Client secret\n\n Your app can access the enabled Google APIs using these values.\n\nBefore you can launch a public application that accesses the Photos APIs,\nyour app must be reviewed by Google. An \"Unverified app\" message appears on the\nscreen when you test your application, until it is\n[verified](https://support.google.com/cloud/answer/7454865).\n\nAfter you've configured your app you're ready to get started:\n\n- [Get started with the Picker API](/photos/picker/guides/get-started-picker)\n- [Get started with the Library API](/photos/library/guides/get-started-library)\n\nChanging your client ID\n-----------------------\n\nResources created through any of the Google Photos APIs can only be accessed or\nmodified using the original client ID used to create them. For example, if you\ncreate a `session` in the Picker API with a specific client ID and later change\nthat client ID in your app, your app will lose access to any API resources\ncreated with the previous client ID.\n\nPlan carefully and choose the correct client ID type for the Photos API you are\nusing. Only change your client ID if absolutely necessary to avoid access\nissues."]]
