If the APIs Explorer isn't visible, click\n**Try it!** to display the condensed version of the APIs Explorer.\n\nIf **Try it!** doesn't appear on the right-hand side of a reference\ndocumentation page, the method isn't supported by the APIs Explorer. For\nexample, the APIs Explorer isn't compatible with APIs that require service\naccounts, so it doesn't appear on documentation pages for those APIs.\n\nDisplay the expanded version of the APIs Explorer\n-------------------------------------------------\n\nThe expanded version of the APIs Explorer contains cURL, HTTP, and possibly\nother code samples. To display the expanded version of the APIs Explorer,\nclick Full screen fullscreen.\n| **Note:** To run the code samples, you must generate and use your own authorization credentials. For an explanation of how to create a project and generate credentials, refer to your specific Google API's documentation.\n\nExecute a method\n----------------\n\nThe APIs Explorer lets you enter required parameters, optional parameters,\nand, if applicable, a request body for API methods. For many REST methods,\nsuch as list methods, you only need to fill one or two fields before you can\nexecute the method. For example, the Books API's\n[`books.volumes.list`](/books/docs/v1/reference/volumes/list)\nmethod only requires a query parameter (`q`) to list books. To try the\n[`books.volumes.list`](/books/docs/v1/reference/volumes/list)\nmethod:\n\n1. Navigate to [`books.volumes.list`](/books/docs/v1/reference/volumes/list).\n2. If the APIs Explorer isn't displayed, click **Try it!**\n3. In the **`q`** field, type *Hunger Games* (without any quotes or special characters).\n4. Scroll down and click **Execute**.\n5. (optional) A Google sign-in screen asks you to select a Google account.\n6. (optional) A Google authorization dialog asks you if it's okay to \"Manage your books.\" Click *Allow*. The results appear below the Execute button.\n\nIf the APIs Explorer shows a result of 200, then the method was successful.\n| **Note:** After you allow the authorization screen to make an authorized request, the APIs Explorer is authorized to make other requests until the credentials expire. Therefore, you don't see the authorization screen for every subsequent method call. For further information on credentials, see [Test with different credential types and scopes](/explorer-help/authorization-and-authentication).\n\nTroubleshoot APIs Explorer issues\n---------------------------------\n\n### You received a 401 or 403 error\n\nIf you're getting a 401 or 403 error when executing a method using the APIs\nExplorer, it is likely due to a problem with one of the following:\n\n- You're using the wrong authorization type (API key instead of OAuth 2.0). Try switching the authorization type.\n- You're using OAuth 2.0, but with too narrow a scope. Try using a broader scope.\n\n### Authorization dialog doesn't appear\n\nThe APIs Explorer uses a popup to grant access to your private data. If your\nbrowser blocks popups, this popup won't appear and you won't be able to grant\naccess.\n\nIf you click **Allow** in the authorization dialog and nothing happens, try\nchanging your browser's popup settings to enable popups."]]
