+## Export Document/PDF with Authentication
+
+You can add additional data while exporting a document from the Rich Text Editor. When exporting, the OnExport event is triggered, allowing you to:
+
+- Add custom headers to the request using the `CurrentRequest` property (for example, passing an authentication token).
+
+- Send custom form data to the server using the `CustomFormData` property.
+
+On the server side, you can fetch the authentication token from the request headers and retrieve the custom form data.
+
+The following example demonstrates how to achieve this:
