@anonymous Yep, that seems to do the trick, awesome. I've been trying to figure this out for the past day :)

@anonymous With your help last time (about 1 day ago), it's kinda of working but how would I pass the "data" the mobile number to the xhttp post request?

var xhttp = new XMLHttpRequest();
xhttp.open("POST", "https://app.domain.co/demo/send", true);
xhttp.send('WHAT DO I PASS HERE');
xhttp.send(this.value);

Can anyone give me a hand on this please, really need some help to get this finished & working.
