SDKs & Code Examples

Invoro doesn’t currently provide official SDK libraries, but the REST API is straightforward to use with any HTTP client.

PHP (Guzzle)

use GuzzleHttp\Client;

$client = new Client([
    'base_uri' => 'https://api.invoro.eu/invoice-api/',
    'headers' => [
        'X-Api-Key' => getenv('INVORO_API_KEY'),
        'Accept' => 'application/json',
    ],
]);

// List invoices
$response = $client->get('invoices', [
    'query' => ['direction' => 'outgoing', 'per_page' => 50],
]);
$data = json_decode($response->getBody(), true);

foreach ($data['data'] as $invoice) {
    echo "{$invoice['invoice_number']}: {$invoice['state']}\n";
}

Node.js (fetch)

const API_KEY = process.env.INVORO_API_KEY;
const BASE_URL = 'https://api.invoro.eu/invoice-api';

async function listInvoices() {
  const response = await fetch(`${BASE_URL}/invoices?direction=outgoing`, {
    headers: {
      'X-Api-Key': API_KEY,
      'Accept': 'application/json',
    },
  });

  const { data } = await response.json();

  for (const invoice of data) {
    console.log(`${invoice.invoice_number}: ${invoice.state}`);
  }
}

Python (requests)

import os
import requests

API_KEY = os.environ['INVORO_API_KEY']
BASE_URL = 'https://api.invoro.eu/invoice-api'

def list_invoices():
    response = requests.get(
        f'{BASE_URL}/invoices',
        headers={
            'X-Api-Key': API_KEY,
            'Accept': 'application/json',
        },
        params={'direction': 'outgoing'},
    )
    response.raise_for_status()
    data = response.json()

    for invoice in data['data']:
        print(f"{invoice['invoice_number']}: {invoice['state']}")
