        type: 'GET', // default is GET but you can use other verbs based on your needs.
        cache: true, // default is true, but false for dataType 'script' and 'jsonp', so set it on need basis.
        data: {}, // add your request parameters in the data object.
        dataType: 'json', // specify the dataType for future reference
        jsonp: 'callback', // only specify this to match the name of callback parameter your API is expecting for JSONP requests.
        statusCode: { // if you want to handle specific error codes, use the status code mapping settings.
            404: handler404,
