Google のクライアント ID とクライアント シークレット。OAuth 2.0 リクエストでリクエストの送信元を識別するために使用されるクライアント ID と、リクエストの偽造を防ぐために使用されるクライアント シークレットを Google に割り当てる必要があります。Google クライアント ID とクライアント シークレットには、任意の URL 安全な文字列値を指定できます。クライアント シークレットは、Google とサービスのみに表示されるようにする必要があります。
省略可能なスコープ文字列。API で利用できるユーザーデータの量と種類に応じて、さまざまなカテゴリのユーザーデータを表すスコープを定義できます。これにより、特定の種類のデータへのアクセスについてのみユーザーに権限を求めることができ、クライアントが利用できるデータを承認済みのスコープのみに制限できます。特に、サービスで Google との統合に必要なデータよりも多くのデータを利用可能にする場合は、スコープを使用して一部のデータのみへのアクセス権を付与できます。

Traffic should be accepted\n over HTTPS only. For example, `https://myservice.example.com/auth`.\n Oftentimes an existing sign-in page can be adapted to serve as the\n authorization endpoint.\n\n The `redirect_uri` sent as a parameter to your authorization endpoint will have the following form: \n\n ```\n https://oauth-redirect.googleusercontent.com/r/YOUR_PROJECT_ID\n https://oauth-redirect-sandbox.googleusercontent.com/r/YOUR_PROJECT_ID\n ```\n\n \u003cbr /\u003e\n\n The`redirect_uri` should be allowlisted for the `client_id` you assign to Google.\n- **Token endpoint URL** .\n This is the URL for the\n [token endpoint](https://tools.ietf.org/html/rfc6749#section-3.2)\n which you host and Google makes calls to. Traffic should be accepted over\n HTTPS and only from other known services (such as Google's).\n For example, `https://oauth2.example.com/token`.\n The authorization and token endpoints may be hosted on different domains.\n\n- **Optional token revocation endpoint URL** .\n This is the URL for the\n [revocation endpoint](https://tools.ietf.org/html/rfc7009)\n which you host and Google makes calls to. Traffic should be accepted over\n HTTPS and only from other known services (such as Google's).\n For example, `https://oauth2.example.com/revoke`.\n Your authorization, token and revocation endpoints may be hosted on different\n domains.\n\n- **Optional Cross-Account Protection (RISC) URL**.\n This is a URL you host and Google makes calls to. You may chose the value.\n\n- **Client ID and client secret for Google**.\n You must assign Google a client ID, which is used in OAuth 2.0 requests to\n identify the request's origin, and a client secret, which is used to prevent\n request forgery. The Google client ID and client secret can be any URL-safe\n string values of your choice. You must ensure that the client secret is\n visible to only Google and your service.\n\n- **Optional scope strings**.\n Depending on how much and what kind of user data your API makes available,\n you might want to define scopes that represent different categories of user\n data. By doing so, parties can ask permission from your users to access only\n certain kinds of data, and restrict the data available to clients to only the\n authorized scopes. In particular, if your service makes more data available\n than necessary for integration with Google, you might use scopes to grant\n access to only some of the data.\n\n\u003c!-- --\u003e\n\n- **Your Google API Project ID**\n\n To view your project ID:\n 1. Go to the [Google API Console](https://console.developers.google.com/project).\n 2. Find your project in the table on the landing page. The project ID appears in the **ID** column.\n\n| **Note:** Requests to your OAuth endpoints can come from any number of Google IP Address. We do not recommend maintaining a list of allowed IPs and Google does not publish such a list. This is because the list is dynamic and subject to change at any time. Such a list will become outdated and lead to outages and a poor experience for users. Instead, a reverse lookup to confirm requests originate from Google can be used.
