Hello, I have the same problem. REST API v2, sandbox, JS SDK. Here comes the code:
https://www.paypal.com/sdk/js?currency=EUR&client-id=<<client-id>>
<script>
paypal.Buttons({
createOrder: function(data, actions) {
return actions.order.create({
purchase_units: [{
amount: {
currency_code: 'EUR',
value: '',
breakdown: {
item_total: {
currency_code: 'EUR',
value: ''
},
shipping: {
currency_code: 'EUR',
value: '0.00'
}
}
}
}]
});
},
onShippingChange: function(data, actions) {
country = data.shipping_address.country_code;
$.ajax({
url: '<>',
data: {country: country},
dataType: 'json',
method: 'GET'
}).done(function(ret) {
if(ret.status == 'ok') {
alert(JSON.stringify(ret));
if(ret.shipping_charge > 0) {
alert("will do a patch");
return actions.order.patch([
{
op: 'replace',
path: "/purchase_units/@reference_id=='1'/amount",
value: {
currency_code: 'EUR',
value: parseFloat(ret.order_total).toFixed(2),
breakdown: {
item_total: {
currency_code: 'EUR',
value: parseFloat(ret.items_total).toFixed(2)
},
shipping: {
currency_code: 'EUR',
value: parseFloat(ret.shipping_charge).toFixed(2)
}
}
}
}
]);
} else {
return actions.reject();
}
} else {
return actions.reject();
}
});
},
onApprove: function(data, actions) {
alert(JSON.stringify(data));
},
onCancel: function (data, actions) {
}
}).render('#paypal-button-container');
</script>
I did follow the guide here - https://developer.paypal.com/docs/checkout/integration-features/shipping-callback/
And when AJAX load data and returns them (without any error) the PayPal return error when tries to patch the order:
Error: Order could not be patched at https://www.sandbox.paypal.com/smart/buttons?onShippingChange=true&style.layout=vertical&style.color... ... string truncated .....
Any idea what is wrong? I tried to switch it to production keys and environment and same issue.
Thank you.
