what is best method to include a external url based script in react?
which also implements callbacks
example like

 <script src="https://gateway.card.com/static/checkout/checkout.min.js" data-error="errorCallback" data-cancel="cancelCallback"></script>
        <script type="text/javascript">
            function errorCallback(error) {
                  console.log(JSON.stringify(error));
            }
            function cancelCallback() {
                  console.log('Payment cancelled');
            }
            Checkout.configure({
              session: { 
                id: '<your_initiate_checkout_session_ID>'
                   }
            });
        </script>
