A JavaScript Ajax request embedded in a HTML file which calls a PHP script when the web page is served. This sends the message
You have a new website visitor
to a Slack messenger channel when ran. Uses the Slack API and requires a few values to be input into the PHP script.
There is another Post method in the PHP script, which uses IPify to get the client IP address and if there are no Adblockers enabled, uses this to get the GPS location from IP API. This visitor information is then sent as a Slack message.
