To use the OAuth 2.0 Playground:\n\n1. Open the [OAuth 2.0 Playground](https://developers.google.com/oauthplayground/#step1&scopes=https%3A//www.googleapis.com/auth/cloud-platform&url=https%3A//appengine.googleapis.com/v1/apps/%7BappsId%7D/services/default&content_type=application/json&http_method=GET&useDefaultOauthCred=unchecked&oauthEndpointSelect=Google&oauthAuthEndpointValue=https%3A//accounts.google.com/o/oauth2/v2/auth&oauthTokenEndpointValue=https%3A//oauth2.googleapis.com/token&includeCredentials=unchecked&accessTokenType=bearer&autoRefreshToken=unchecked&accessType=offline&forceAprovalPrompt=checked&response_type=code).\n2. In Step 1, the **https://www.googleapis.com/auth/cloud-platform** scope is pre-selected for you. Click **Authorize APIs** to start the authentication flow.\n3. Follow the \"implicit authentication flow\" by clicking **Allow** to authorize the Google OAuth 2.0 Playground access to your Google Cloud services.\n4. In Step 2, click **Exchange authorization code for tokens** to receive an\n access token.\n\n | **Note:** You can use these access tokens in HTTP requests that you want to run from the command line, as long as you do so prior to their expiration time. For example, use these access tokens to run cURL commands.\n5. In Step 3, the **Request URI** field is pre-populated with the example URI:\n\n https://appengine.googleapis.com/v1/apps/{appsId}/services/default\n\n You must replace `{appsId}` with your Google Cloud Platform project ID\n and then click `Send the request` to view the details about the\n `default` service of your project.\n\n Use this URI field to send HTTP requests against the resources that you\n specify in your project. For more information about specifying resources in\n request URIs, see\n [REST in the Admin API](/appengine/docs/admin-api/rest-in-the-api).\n | **Tip:** You can also click **List possible operations** and then scroll to the **App Engine Admin API** section to view a list of HTTP request. If you select an operation, it will populate the **Request URI** field with a template URI, in which you must specify the IDs of your resources before sending the request.\n\nAPIs Explorer\n-------------\n\nUse the **APIs Explorer** to view a list of all the Admin API\nmethods, fields, and their descriptions. You can then click the items in the\nlist to generate URIs and send HTTP requests against the resources that you\nspecify.\n| **Tip:** You can also use the APIs Explorer widgets in each of the API methods, for example [`apps.get`](/appengine/docs/admin-api/reference/rest/v1/apps/get#try-it).\n\nTo use the APIs Explorer:\n\n1. Open the [APIs Explorer](http://developers.google.com/apis-explorer/#p/appengine/v1/).\n2. Select the method that you want to try out.\n3. Specify the IDs of the resources in your project as well as any supported fields.\n4. Click **Execute** to send the HTTP request against your project and then view both the generated request URI and HTTP response.\n\nWhat's next\n-----------\n\n- [Accessing the API](/appengine/docs/admin-api/accessing-the-api)"]]
