Developing with Admin

A logistics company that uses an Adobe Commerce extension sends every client a CSV file containing a list of reviewed shipment fees each month. The merchant uploads this CSV file to a “file upload” field in Adobe Commerce Admin configuration.

Which two requirements are needed to display the “file upload” field and process the actual CSV import?

Choose two
Explanation

Adobe Commerce system configuration fields use a <backend_model> declaration to associate custom save-time processing with the field. A backend model extending Magento\Framework\App\Config\Value can implement afterSave() and invoke the CSV upload/import service when the configuration is saved. A field type by itself renders an input but does not connect the custom importer to the save lifecycle.
