OAuth 设置

All Google AdMob API calls must be authorized through OAuth2 so your app can interact with web services on the user's behalf. OAuth2 enables your AdMob API client app to access a user's AdMob account without having to handle or store the user's username or password. For an overview of authorization, see Authorization.

Perform the following steps to generate the OAuth2 credentials and make your first request.

Prerequisites

• A Google Account.

• A Google AdMob account.

• Familiarity with REST basics and authorizing requests with OAuth 2.0.

Determine your authentication type

Check the table below to see which authentication type is most appropriate for your app:

Choose your OAuth2 authentication type	If ...
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.
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.

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.

Create a project

To get started using the AdMob API, you need to first create or select a project in the Google API Console and enable the API using the setup tool, which guides you through the process and activates the AdMob API automatically.

Enabling the API for an existing project

The following steps apply to users who have an existing project and prefer to activate the AdMob API for it manually.

为您的项目启用API：

1. Open the API Library中的Google API Console 。
2. If prompted, select a project, or create a new one. API Library列出了所有可用的API，并按产品家族和受欢迎程度分组。
3. 如果您要启用的API在列表中不可见，请使用搜索找到它，或单击其所属产品系列中的“ 查看全部 ”。
4. 选择要启用的API，然后单击“ 启用”按钮。
5. If prompted, enable billing.
6. If prompted, read and accept the API's Terms of Service.

Create OAuth2 credentials

The following instructions guide you through the process of creating an OAuth 2.0 client ID to use with the installed app flow.

1. Go to the Credentials page.

2. Click CREATE CREDENTIALS > OAuth client ID.

   If you hadn't configured an OAuth consent screen for this project previously, you'll be directed to do so now. Click CONFIGURE CONSENT SCREEN. There are multiple ways to configure your consent screen to use your OAuth 2.0 client ID.

   1. Set your user type to External and publishing status to Published.

   2. Or, set your user type to External and publishing status to Testing, then add Test users by selecting add users to give them access to use your OAuth 2.0 client ID.

      See additional information on setting up your OAuth consent screen.

3. Select Desktop app or Web Application as the application type, give it a name, then click Create.

When done, you are presented with an OAuth 2.0 client ID and client secret, which you can download in JSON format and save for later use.

Make a request

The AdMob API is built on HTTP and JSON, so any standard HTTP client can send requests to it and parse the responses. However, the Google API client libraries provide better language integration, improved security, and support for making authorized requests. The client libraries are available in a number of programming languages; by using them you can avoid the need to manually set up HTTP requests and parse the responses.

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.

With OAuth 2.0 credentials created, you're ready to start using the AdMob API. To request access using OAuth 2.0, your app also needs scope information:

Scope	Meaning
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.
https://www.googleapis.com/auth/admob.report	See ad performance and earnings reports. See publisher ID, timezone, and default currency code.

Make your first request to generate a report using examples in Java, PHP, Python or curl.

Revoke shared tokens

You can revoke shared tokens in two ways:

1. Navigate to your Google account permissions page and revoke access from the relevant project.

2. Alternatively, you can revoke web application tokens using the Google Identity API.
