Check the [`Fix OAuth Configuration Errors`](/identity/oauth2/web/guides/error#fix_oauth_configuration_errors) section for more details.\n\nOAuth Error Responses\n---------------------\n\nOAuth may return an error response, in which case your [`callback`](/identity/oauth2/web/reference/js-reference#google.accounts.oauth2.initCodeClient) function\nwill be triggered with the error response as the parameter. The following is an\nexample OAuth error response. \n\n```scdoc\n {\n \"error\":\"access_denied\"\n }\n```\n\nSome examples are:\n\n1. The user denies the OAuth request.\n2. For an OAuth request with [`prompt=none`](/identity/protocols/oauth2/openid-connect#authenticationuriparameters) parameter, the user is not already authenticated and has not pre-configured consent for the requested scopes.\n\nThis example shows how to handle the success and error OAuth responses: \n\n function myCallback(response) {\n if (response.error) {\n // Handle error response\n ... ...\n } else if (response.code) {\n // Handle success code response\n ... ...\n }\n }\n\n| **Note:** OAuth error responses should be handled by your `callback` function.\n\nNon-OAuth Errors\n----------------\n\nOAuth doesn't define the behaviors when:\n\n1. the popup window fails to open.\n2. the popup window is closed before an OAuth response is returned.\n\nThis library captures these errors, and triggers the [`error_callback`](/identity/oauth2/web/reference/js-reference#google.accounts.oauth2.initCodeClient) if\nset. Be sure to check the error type. Otherwise, your code logic may\nbe affected when this library support new error types later. \n\n function myErrorCallback(err) {\n if (err.type == 'popup_failed_to_open') {\n // The popup window is failed to open\n ... ...\n } else if (err.type == 'popup_closed') {\n // The popup window is closed before an OAuth response is returned\n ... ...\n }\n }\n\n const client = google.accounts.oauth2.initCodeClient({\n client_id: 'YOUR_GOOGLE_CLIENT_ID',\n scope: 'https://www.googleapis.com/auth/calendar.readonly',\n ux_mode: 'popup',\n callback: myCallback,\n error_callback: myErrorCallback\n });\n\n| **Note:** Use `error_callback` to capture errors like popup windows are failed to open or closed directly."]]
