PayPal Checkout - Set up the transaction shipping address and shipping amount - paypal

Question

PayPal Checkout
Set up the transaction
allow to set parameters like mount.value: '0.01 and other things like so
<script>
paypal.Buttons({
createOrder: function(data, actions) {
// Set up the transaction
return actions.order.create({
purchase_units: [{
amount: {
value: '0.01'
}
}]
});
}
}).render('#paypal-button-container');
</script>
But I need to set up the shipping address and shipping amount. How can I do it?
PS
I found Orders API Integration Guide for Express Checkout. It has all the options
like details.shipping = 0.00 ...
and shipping_address, but it does not work with PayPal Checkout example. Is it because I'm testing in the sendbox?

Answer 2

basically, the whole idea of placing these details into <script> was a mistake. It should all go from server to server and html should only reflect the reference code.
for PHP users, look into
use PayPalCheckoutSdk\Core\PayPalHttpClient;
use PayPalCheckoutSdk\Core\PayPalEnvironment;
use PayPalCheckoutSdk\Orders\OrdersCreateRequest;
