Shipping address callback
When there are changes in the shipping address in the checkout, a callback is sent to session.express.shipping_address_callback
with the new address.
The webshop should update the webshop state/order with the new shipping address, and (if shipping in iframe
is
enabled) return the new list of available shipping options.
Look here for the documentation of the callback.
If the checkout is embedded, the Dintero Web SDK will call onSession
whenever the session is updated, with the
event SessionUpdated
.
