完成后，系统会显示一个 OAuth 2.0 客户端 ID 和客户端密钥，您可以将其下载为 JSON 格式进行保存，以备日后使用。
发出请求
AdMob API 是基于 HTTP 和 JSON 构建的，因此任何标准 HTTP 客户端均可向其发送请求并解析响应。不过，使用 Google API 客户端库将为您带来优势，例如语言集成更出色、安全性更高，且支持发出经过授权的请求。客户端库支持多种编程语言；使用客户端库可以避免手动设置 HTTP 请求和手动解析响应。
创建 OAuth 2.0 凭据后，您便可以开始使用 AdMob API 了。如需通过 OAuth 2.0 请求访问权限，您的应用还需要授权范围信息：

First, create or select a project in the Google API Console and enable the AdMob API. Next, create OAuth2 credentials, choosing between \"Desktop app\" or \"Web app\" authentication types based on your needs. Configure the OAuth consent screen, download the generated client ID and secret, and then use these credentials to authorize requests with specified scopes, such as `admob.monetization` or `admob.readonly`. To start making requests, you can utilize the Google API client libraries. If you want to revoke access, you can do so from your Google account or using Google Identity API.\n"],null,["All Google AdMob API calls must be authorized through\n[OAuth2](/identity/protocols/oauth2) so your app can interact with web services\non the user's behalf. OAuth2 enables your AdMob API client app to access a\nuser's AdMob account without having to handle or store the user's username or\npassword. For an overview of authorization, see\n[Authorization](/admob/api/v1/how-tos/authorizing).\n\nPerform the following steps to generate the OAuth2 credentials and make your\nfirst request.\n\nPrerequisites\n\n- A [Google Account](//google.com/accounts/NewAccount).\n\n- A [Google AdMob account](//admob.google.com/home/get-started).\n\n- Familiarity with [REST basics](/admob/api/v1/prereqs#rest) and [authorizing requests with\n OAuth 2.0](/admob/api/v1/how-tos/authorizing).\n\nDetermine your authentication type\n\nCheck the table below to see which **authentication type** is most appropriate\nfor your app:\n\n| Choose your OAuth2 authentication type | If ... |\n|----------------------------------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|\n| **Desktop app** | - You're managing all of your AdMob API accounts using a single top level manager account. - You're a first-time user, or want to get started quickly with the simplest setup. - Your app only authenticates Google AdMob users from one machine. |\n| **Web app** | - You want to authenticate as a user who can grant permission to your app to access their AdMob API account data. - You want to easily generate multiple authorization credentials, to manage third-party accounts for example. - Your app requires callback URLs. Callback URLs are not supported in the desktop app flow. |\n\n| **Key Point:** You can still choose the desktop app flow even if you're developing an app to run on a server. The difference is whether the OAuth authorization is completed locally or remotely. A desktop flow requires authorization to be completed on the local machine, whereas the web-flow lets authorization be completed on Google's authorization server.\n\nCreate a project\n\nTo get started using the AdMob API, you need to first create or select a\nproject in the Google API Console and enable the API using [the setup\ntool](https://console.cloud.google.com/start/api?id=admob.googleapis.com&credential=client_key),\nwhich guides you through the process and activates the AdMob API\nautomatically. \n\nEnabling the API for an existing project\n\nThe following steps apply to users who have an existing project and prefer to\nactivate the AdMob API for it manually.\n\nTo enable an API for your project:\n\n1. [Open the API Library](https://console.developers.google.com/apis/library) in the Google API Console.\n2. If prompted, select a project, or create a new one. The API Library lists all available APIs, grouped by product family and popularity.\n3. If the API you want to enable isn't visible in the list, use search to find it, or click **View All** in the product family it belongs to.\n4. Select the API you want to enable, then click the **Enable** button.\n5. If prompted, enable billing.\n6. If prompted, read and accept the API's Terms of Service.\n\nCreate OAuth2 credentials\n\nThe following instructions guide you through the process of creating an OAuth\n2.0 client ID to use with the [installed app\nflow](/identity/protocols/OAuth2InstalledApp).\n\n1. Go to the [Clients page](https://console.developers.google.com/auth/clients).\n2. Click **CREATE CREDENTIALS \\\u003e OAuth client ID**.\n\n If you hadn't configured an OAuth consent screen for this project\n previously, you'll be directed to do so now. Click **CONFIGURE CONSENT\n SCREEN**. There are multiple ways to configure your consent screen to\n use your OAuth 2.0 client ID.\n 1. Set your user type to **External** and publishing status to **Published**.\n 2. Or, set your user type to **External** and publishing status to\n **Testing** , then add **Test users** by selecting **add users** to\n give them access to use your OAuth 2.0 client ID.\n\n See additional information on [setting up your OAuth consent\n screen](//support.google.com/cloud/answer/10311615).\n3. Select **Desktop app** or **Web Application** as the application type, give\n it a name, then click **Create**.\n\nWhen done, you are presented with an OAuth 2.0 client ID and client secret,\nwhich you can download in JSON format and save for later use.\n\nMake a request\n\nThe AdMob API is built on HTTP and JSON, so any standard HTTP client can send\nrequests to it and parse the responses. However, the [Google API client\nlibraries](/admob/api/v1/libraries) provide better language integration,\nimproved security, and support for making authorized requests. The client\nlibraries are available in a number of programming languages; by using them you\ncan avoid the need to manually set up HTTP requests and parse the responses.\n| **Note:** The first time you activate the OAuth flow, you are asked to provide your AdMob publisher ID and accept an authorization prompt in your browser. Before accepting, make sure you're signed in with a Google Account that has access to your AdMob account. Your app is then authorized to access data on behalf of whichever account is currently logged in.\n\nWith [OAuth 2.0 credentials created](#credentials), you're ready to start using\nthe AdMob API. To request access using OAuth 2.0, your app also needs scope\ninformation:\n\n\n| Scope | Meaning |\n|--------------------------------------------------|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|\n| `https://www.googleapis.com/auth/admob.readonly` | See all AdMob data. This may include account information, inventory and mediation settings, reports, and other data. This doesn't include sensitive data, such as payments or campaign details. |\n| `https://www.googleapis.com/auth/admob.report` | See ad performance and earnings reports. See publisher ID, timezone, and default currency code. |\n\n\u003cbr /\u003e\n\n\u003cbr /\u003e\n\nMake your first request to generate a report using examples in\n[Java](/admob/api/v1/reporting#java-client-library),\n[PHP](/admob/api/v1/reporting#php-client-library),\n[Python](/admob/api/v1/reporting#python-client-library) or\n[curl](/admob/api/v1/reporting#curl-command-line).\n\nRevoke shared tokens\n\nYou can revoke shared tokens in two ways:\n\n1. Navigate to your [Google account\n permissions page](//myaccount.google.com/permissions) and revoke access from\n the relevant project.\n\n2. Alternatively, you can revoke web application tokens using the [Google\n Identity API](/identity/protocols/oauth2/web-server#tokenrevoke)."]]
