Request Verification

You must verify these request signatures using the Signing Secret found in your Merchant Dashboard > Settings > Keys and URLs > Keys.

$hmac_header = $_SERVER['X-Novatum-Hmac-Sha256'];

function verify_webhook($payload, $hmac_header) {
    $computed_hmac = base64_encode(hash_hmac('sha256', $payload, NOVATUM_SIGNING_SECRET, true));
    return ($computed_hmac == $hmac_header);
}
