We are looking to protect downloadable data based on data classification, We have sensistive data which needs to be protected using internal service. Currently, our application uses lot of list views and report definition rules and have 'Export To Excel' functionality. We wanted to call REST service api before download so that data is protected. We see 'ViewExportToExcel' activity is marked as 'Final' and couldn't extend further. Please could you provide us the options to customize from our end to call REST service before download.Please let us know if this can be done.
