Hello,
You must upload the confirmation file to the root directory of your website via FTP (File Transfer Protocol) or your web host's control panel. If you need further assistance with this matter, we suggest that you contact your web hosting company or your web administrator regarding the uploading of the confirmation file (alertpayverification.html).
When done properly, you should be able to view it by visiting "http://yourwebsite.com/alertpayverification.html" from your web browser.
