SendOTP Client Side sample code JavaScript

Index.php

<script type="text/javascript" src="jquery-2.1.4.min.js"></script>
<script type="text/javascript">
function sendOTP() {
	var data = {"countryCode": "country code", "mobileNumber": "Mobile number to be verified"};
	$.ajax({
		url: 'http://Your-domain-name/path/sendotp.php?action=generateOTP',
		type: 'POST',
		dataType: 'json',				
		data: data,
		success: function(data){
			var resp = JSON.parse(response)
			console.log(resp.status);
		},
		error: function(jqXHR, textStatus, ex) {
	        console.log(textStatus + "," + ex + "," + jqXHR.responseText);
		}
	});
}

function verifyOTP() {
	var data = {"countryCode": "country code", "mobileNumber": "Mobile number to be verified","oneTimePassword":"One time password"};
	$.ajax({
		url: 'http://Your-domain-name/path/sendotp.php?action=verifyOTP',
		type: 'POST',
		dataType: 'json',				
		data: data,
		success: function(data){
			var resp = JSON.parse(response)
			console.log(resp.status);
		},
		error: function(jqXHR, textStatus, ex) {
	        console.log(textStatus + "," + ex + "," + jqXHR.responseText);
	    }
	});
}
</script>

success part of AJAX should be:

success: function(response){
console.log(response.message);
}
