多语言发票生成API

接入教程

1. 访问Invovate官网注册获取API密钥
2. 准备包含发票数据的JSON请求体
3. 向API端点发送POST请求
4. 接收生成的PDF、JSON或UBL格式发票
5. 根据需要配置输出语言（支持11种）

使用Python生成多语言发票

python

import requests
import json

url = "https://api.example.com/v1/invoices"
api_key = "YOUR_API_KEY"

headers = {
    "Authorization": f"Bearer {api_key}",
    "Content-Type": "application/json"
}

# 示例发票数据
invoice_data = {
    "invoice": {
        "language": "en",
        "currency": "USD",
        "items": [
            {"description": "Web Design Service", "quantity": 1, "unit_price": 500}
        ]
    },
    "output_formats": ["pdf", "json", "ubl"]
}

response = requests.post(url, headers=headers, json=invoice_data)

if response.status_code == 200:
    result = response.json()
    print("Invoice generated successfully:", result)
else:
    print(f"Error: {response.status_code}", response.text)

使用PHP调用发票生成API

php

<?php

$url = "https://api.example.com/v1/invoices";
$api_key = "YOUR_API_KEY";

$data = [
    "invoice" => [
        "language" => "zh",
        "currency" => "CNY",
        "items" => [
            ["description" => "软件开发服务", "quantity" =>161, "unit_price" => 1500]
        ]
    ],
    "output_formats" => ["pdf", "json"]
];

$ch = curl_init($url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($data));
curl_setopt($ch, CURLOPT_HTTPHEADER, [
    "Authorization: Bearer " . $api_key,
    "Content-Type: application/json"
]);

$response = curl_exec($ch);
$http_code = curl_getinfo($ch, CURLINFO_HTTP_CODE);
curl_close($ch);

if ($http_code == 200) {
    $result = json_decode($response, true);
    echo "发票生成成功：";
    print_r($result);
} else {
    echo "错误代码：{$http_code}\n";
    echo $response;
}

?>

使用JavaScript生成发票

javascript

const apiUrl = "https://api.example.com/v1/invoices";
const apiKey = "YOUR_API_KEY";

const invoiceData = {
    invoice: {
        language: "de",
        currency: "EUR",
        items: [
            {description: "IT Consulting", quantity: 2, unit_price: 750}
        ]
    },
    output_formats: ["pdf", "ubl"]
};

async function generateInvoice() {
    try {
        const response = await fetch(apiUrl, {
            method: "POST",
            headers: {
                "Authorization": `Bearer ${apiKey}`,
                "Content-Type": "application/json"
            },
            body: JSON.stringify(invoiceData)
        });

        if (response.ok) {
            const result = await response.json();
            console.log("Invoice generated:", result);
        } else {
            console.error(`Error: ${response.status}`, await response.text());
        }
    } catch (error) {
        console.error("Request failed:", error);
    }
}

generateInvoice();

常见问题

API支持哪些输出格式？

支持PDF、JSON和UBL三种格式。您可以通过output_formats参数指定一种或多种格式，API将返回相应格式的发票数据。

发票数据中的语言字段支持哪些选项？

目前支持11种语言：英语（en）、中文（zh）、德语（de）、法语（fr）、西班牙语（es）、日语（ja）、韩语（ko）、意大利语（it）、葡萄牙语（pt）、俄语（ru）和荷兰语（nl）。
