Button export csvHtml5 - skip download

Hi,
I want to send the CSV data to the server and not download it
i am using the following export settings.

! exportOptions: {
! modifier: {
! search: 'applied',
! page : 'all'
! },
! columns: ':not(:first-child)',
! columns: ':visible'
! },
! extension: '.csv',
! fieldSeparator: ';',

How do I prevent only the download?
