function s2_payment_notification()
{

if( isset($_POST['user_id'], $_POST['subscr_id'], $_POST['user_ip'],$_POST['user_piva']))
    {
        $user_id             = (integer)$_POST['user_id'];
        $subscr_id           = (string)$_POST['subscr_id'];
        $user_ip             = (string)$_POST['user_ip'];
        $user_piva           = (integer)$_POST['user_piva'];

        $s2member_subscr_id  = get_user_option('s2member_subscr_id', $user_id);
        $s2member_registration_ip = get_user_option('s2member_registration_ip', $user_id);
        $s2member_p_iva_fisc = get_user_option('p_iva_fisc', $user_id);

        $user_piva = wp_json_encode($s2member_p_iva_fisc);
        $user_ip = wp_json_encode($s2member_registration_ip);
        $subscr_id = wp_json_encode($s2member_subscr_id);

        wp_remote_post('http://1.2.3.123:49005/SingleMethodName=DomainManagementStripeService___DomainRegistration', [
            'headers' => ['content-type' => 'application/json'],
            'body' => array(

                'subscr_id' => '$subscr_id',

    else {
        wp_remote_post('http://1.2.3.123:49005/SingleMethodName=DomainManagementStripeService___DomainRegistration', [
            'headers' => ['content-type' => 'application/json'],

Sending and receiving data in JSON format using POST method

xhr = new XMLHttpRequest();
var url = "url";
xhr.open("POST", url, true);
xhr.setRequestHeader("Content-type", "application/json");
xhr.onreadystatechange = function () { 
    if (xhr.readyState == 4 && xhr.status == 200) {
        var json = JSON.parse(xhr.responseText);
        console.log(json.email + ", " + json.password)
    }
}
var data = JSON.stringify({"email":"hey@mail.com","password":"101010"});
xhr.send(data);

Sending a receiving data in JSON format using GET method

xhr = new XMLHttpRequest();
var url = "url?data=" + encodeURIComponent(JSON.stringify({"email":"hey@mail.com","password":"101010"}));
xhr.open("GET", url, true);
xhr.setRequestHeader("Content-type", "application/json");
xhr.onreadystatechange = function () { 
    if (xhr.readyState == 4 && xhr.status == 200) {
        var json = JSON.parse(xhr.responseText);
        console.log(json.email + ", " + json.password)
    }
}
xhr.send();

Handling data in JSON format on the server-side using PHP

// Handling data in JSON format on the server-side using PHP
header("Content-Type: application/json");
// build a PHP variable from JSON sent using POST method
$v = json_decode(stripslashes(file_get_contents("php://input")));
// build a PHP variable from JSON sent using GET method
$v = json_decode(stripslashes($_GET["data"]));
// encode the PHP variable to JSON and send it back on client-side
echo json_encode($v);

  • this is actually unlikely to work as it misses the critical part of doing it only after successful registration which with email validation will probably happen away from the registration page – Mark Kaplun Mar 9 '17 at 14:37

The trivial way to do this is to use the register_user action hook that fires immediately after a user is added to the database. It passes one variable to the callbacks, $user_id, that can be used to wp_safe_remote_post().

namespace StackExchange\WordPress;

function register_user( $user_id ) {
  $url = 'https://example.com';
  $args = [
    'user_id' => $user_id,
  ];
  \wp_safe_remote_post( $url, $args );
}
\add_action( 'register_user', __NAMESPACE__ . '\register_user' );
