Feel free to search this API through the search bar or the navigation tree in the sidebar.

# exporting.formAttributes

Highcharts v11.2.0 and older. An object containing additional key value data for the POST form that sends the SVG to the export server. For example, a `target` can be set to make sure the generated image is received in another frame, or a custom `enctype` or `encoding` can be set.

With Highcharts v11.3.0, the `fetch` API replaced the old HTML form. To modify the request, now use fetchOptions instead.
