+/**
+ * Helper function to authenticate with only an API key using ImportJSONAdvanced
+ *
+ * Imports a JSON feed and returns the results to be inserted into a Google Spreadsheet. The JSON feed is flattened to create
+ * a two-dimensional array. The first row contains the headers, with each column header indicating the path to that data in
+ * the JSON feed. The remaining rows contain the data.
+ *
+ * The fetchOptions can be used to change how the JSON feed is retrieved. For instance, the "method" and "payload" options can be
+ * set to pass a POST request with post parameters. For more information on the available parameters, see
+ * https://developers.google.com/apps-script/reference/url-fetch/url-fetch-app .
+ *
+ * Use the include and transformation functions to determine what to include in the import and how to transform the data after it is
+ * imported.
