PayPal Checkout (javascript) с кнопками Smart Payment создает проблему заказа

Question

Я пытаюсь внедрить на своей веб-странице PayPal Checkout (javascript), следуя инструкции: https://developer.paypal.com/docs/checkout/ Все отлично со стандартными опциями. Например, это работает просто отлично:

paypal.Buttons({
            createOrder: function(data, actions) {
                return actions.order.create({
                    purchase_units: [{
                        amount: {
                            currency_code: 'EUR',
                            value: '120.16'
                        },
                        description: 'Purchase Unit test description',
                        custom_id: '64735',
                    }]
                });
            },
            onApprove: function(data, actions) {
                return actions.order.capture().then(function(details) {
                    alert('Transaction completed by ' + details.payer.name.given_name);
                    // Call your server to save the transaction
                    return fetch('/api/paypal-transaction-complete', {
                        method: 'post',
                        headers: {
                            'content-type': 'application/json'
                        },
                        body: JSON.stringify({
                            orderID: data.orderID
                        })
                    });
                });
            }
        }).render('#paypal-button-container');

Но когда я пытаюсь быть более точным в деталях заказа, появляется сообщение об ошибке:

Error: "Order Api response error: 
{ 
    "name": "INVALID_REQUEST", 
    "message": "Request is not well-formed, syntactically incorrect, or violates schema.", 
    "debug_id": "1ed03d18530c1", 
    "details": [ 
        { 
            "location": "body", 
            "issue": "INVALID_SYNTAX", 
            "description": "Cannot deserialize instance of `com.paypal.api.platform.checkout.orders.v2.model.AmountBreakdown` out of START_ARRAY token line: 1, column: 82" 
            } 
            ], 
            "links": [ 
                { 
                    "href": "https://developer.paypal.com/docs/api/orders/v2/#error-INVALID_SYNTAX", "rel": "information_link", "encType": "application/json" 
                } 
            ] 
        }"
}

Это мой код:

paypal.Buttons({
            createOrder: function(data, actions) {
                return actions.order.create({
                    purchase_units: [{
                        amount: {
                            currency_code: 'EUR',
                            value: '120.16',
                            breakdown: [{
                                item_total: {
                                    unit_amount: 7,
                                    currency_code: 'EUR',
                                    value: '120.16'
                                }
                            }]

                        },
                        description: 'Purchase Unit test description',
                        custom_id: '64735',
                        items: [{
                            name: 'Test item 1',
                            unit_amount: {
                                currency_code: 'EUR',
                                value: '60.12'
                            },
                            quantity: 2,
                            description: 'Uaua item 1 description'
                        }, {
                            name: 'Test item 2',
                            unit_amount: {
                                currency_code: 'EUR',
                                value: '60.00'
                            },
                            quantity: 5,
                            description: 'Test item 2 description'
                        }]
                    }]
                });
            },
            onApprove: function(data, actions) {
                return actions.order.capture().then(function(details) {
                    alert('Transaction completed by ' + details.payer.name.given_name);
                    // Call your server to save the transaction
                    return fetch('/api/paypal-transaction-complete', {
                        method: 'post',
                        headers: {
                            'content-type': 'application/json'
                        },
                        body: JSON.stringify({
                            orderID: data.orderID
                        })
                    });
                });
            }
        }).render('#paypal-button-container');

Кто-нибудь знает, в чем проблема? Документация PayPal не очень информативна ...

Answer 1

unit_amount: 7,

Это принадлежит там?Ваша ошибка ссылается на orders.v2.model.AmountBreakdown, и я не вижу это поле в поле Я не вижу его в спецификации API для денежного объекта item_total.

Answer 2

После еще нескольких копаний я нашел правильный формат:

paypal.Buttons({
    createOrder: function(data, actions) {
        return actions.order.create({
            purchase_units: [
            {
                reference_id: "PUHF",
                description: "Some description",

                custom_id: "Something7364",
                soft_descriptor: "Great description 1",
                amount: {
                    currency_code: "EUR",
                    value: "200.00",
                    breakdown: {
                        item_total: {
                            currency_code: "EUR",
                            value: "200.00"
                        }
                    }
                },
                items: [
                    {
                        name: "Item 1",
                        description: "The best item ever",
                        sku: "xyz-2654",
                        unit_amount: {
                            currency_code: "EUR",
                            value: "100.00"
                        },
                        quantity: "1"
                    },
                    {
                        name: "Item 2",
                        description: "Not bad too",
                        sku: "zdc-3942",
                        unit_amount: {
                            currency_code: "EUR",
                            value: "50.00"
                        },
                        quantity: "2"
                    }
                ],

            }
        ]
    });
},
onApprove: function(data, actions) {
    return actions.order.capture().then(function(details) {
        alert('Transaction completed by ' + details.payer.name.given_name);
        // Call your server to save the transaction
        return fetch('/api/paypal-transaction-complete', {
            method: 'post',
            headers: {
                'content-type': 'application/json'
            },
            body: JSON.stringify({
                orderID: data.orderID
            })
        });
    });
}
}).render('#paypal-button-container');

Это пример полного набора опций:
