This feature is useful in ensuring you're using the\nminimal required credentials and scope to invoke an API endpoint.\n\nTest with different credentials\n-------------------------------\n\nBy default, both the OAuth 2 and API Key credential types are checked.\nIf you want to test with only one credential, check on the credential type to\nuse (and uncheck the other credential type). Following are the general rules for\npicking a credential to test with:\n\n- If you're using a method to access public data, such as Google Maps data, you\n can use an API key as your credential. Check **API key** and uncheck\n **Google OAuth 2.0**.\n\n- If you're using a method to access private data, such as the user's Google\n Drive data, you must use an OAuth 2 credential. Uncheck **API key** and check\n **Google OAuth 2.0**.\n\nIf you receive a result of 200, the credential is sufficient\nfor accessing the data. If you receive a result of 401, you need\nto use OAuth 2 credential to access the data.\n\nTest with different scopes\n--------------------------\n\nA scope is a string, such as\n`https://www.googleapis.com/auth/drive.metadata.readonly`, defining a level of\naccess to resources required by your app, such as the level of access to data\nowned by the users. Ideally, you want your app to use scopes with\nthe narrowest level of access to the user's data. Different methods might\nrequire different scopes. For example, a method in an API might require\nat least a read-only scope, while other methods might require a read-write\nscope.\n| **Note:** Scopes are only applicable to Google OAuth 2.0. If you're testing with an API key, you won't test with different scopes.\n\nBy default, all Google OAuth 2.0 scopes for an API are enabled in the APIs\nExplorer. To test with a specific scope:\n\n1. In the Credentials Google OAuth 2.0 section, click **show scopes**.\n2. Check the scope to use when invoking the method.\n3. Click **Execute** to execute the API using only the selected scope. The APIs Explorer shows an authorization screen asking you to grant access to use the scope.\n4. Click **Allow**. The results appear below the Execute button.\n\nIf the APIs Explorer shows a result of 200 under an \"application/json\", then the\nscope is sufficient to invoke the method. If the APIs Explorer shows an\nresult of 403, you have chosen an insufficient scope to invoke the method. Try\na broader scope.\n\nFor additional information on scope selection, refer to the authentication and\nauthorization section of documentation for your specific Google API.\n\n### Revoke authorized access to test with new scopes\n\nAfter you have used the Google authorization screen to approve authorization,\nthe APIs Explorer remains authorized to make authenticated requests as long\nas the credentials aren't expired. Unchecking scopes doesn't reset the\npreviously approved credentials and scopes. If you want to test with a new\nscope configuration, you must revoke your previously approved credentials.\n\nTo revoke the credentials used by the APIs Explorer:\n\n1. Navigate to [Apps with access to your account](https://www.google.com/accounts/IssuedAuthSubTokens).\n2. Under **Third-party apps with account access** , click **Google APIs Explorer**.\n3. Click **Remove Access**.\n4. (optional) Reload the documentation page to reset the APIs Explorer."]]
