Hi @shawna.gerard ,

I got it working as a list UI action on incident table. You'll get one zip for each sys_id passed.

Below is the UI action script:

function downloadAll() {
  selSysIds = g_list.getChecked();
  sysIdList = selSysIds.split(',');
  for (var i=0;i<=sysIdList.length;i++)
  {
    window.open('/download_all_attachments.do?sysparm_sys_id='+sysIdList[i],"_blank");
  }

}

Here's the UI Action screenshot for the setting that I had used:

Thanks & Regards,
