php - Stripe custom checkout - form submit -

i'm trying out stripe api & functions, twisting head around 1 issue - how submit form after (test) payment successful?

here's current code:

<script>     var handler = stripecheckout.configure({         key: 'pk_test_mykey',         image: 'https://stripe.com/img/documentation/checkout/marketplace.png',         locale: 'sv',         token: function(token) {             // can access token id `token.id`.             // token id server-side code use.         }     });       document.getelementbyid('custombutton').addeventlistener('click', function(e) {         stripe_spots = document.getelementbyid("spots").value;         stripe_total = (stripe_spots) * 70;         // open checkout further options:         handler.open({             name: 'revy!',             description: stripe_spots + " platser",             zipcode: true,             currency: 'sek',             amount: stripe_total * 100         });          e.preventdefault();      });       // close checkout on page navigation:      window.addeventlistener('popstate', function() {          handler.close();      });  </script> 

where or when supposed submit form?

thanks!

after retrieving stripe token should send data server including token make stripe charge or create subscription
