+# Facturapi PHP SDK
+
+SDK oficial de PHP para [Facturapi](https://www.facturapi.io).
+
+Idioma: Español | [English](./README.md)
+
+[![Última Versión](https://img.shields.io/packagist/v/facturapi/facturapi-php?style=flat-square)](https://packagist.org/packages/facturapi/facturapi-php)
+[![Versión de PHP](https://img.shields.io/packagist/php-v/facturapi/facturapi-php?style=flat-square)](https://packagist.org/packages/facturapi/facturapi-php)
+[![Descargas Totales](https://img.shields.io/packagist/dt/facturapi/facturapi-php?style=flat-square)](https://packagist.org/packages/facturapi/facturapi-php)
+[![Descargas Mensuales](https://img.shields.io/packagist/dm/facturapi/facturapi-php?style=flat-square)](https://packagist.org/packages/facturapi/facturapi-php)
+[![Licencia](https://img.shields.io/packagist/l/facturapi/facturapi-php?style=flat-square)](https://packagist.org/packages/facturapi/facturapi-php)
+
+## Instalación ⚡
+
+```bash
+composer require facturapi/facturapi-php
+```
+
+Sin Composer (workaround soportado):
+
+```php
+require_once __DIR__ . '/path/to/facturapi-php/src/Facturapi.php';
+```
+
+Requisitos:
+- PHP `>=8.2`
+
+## Inicio Rápido 🚀
+
+```php
+<?php
+
+require_once __DIR__ . '/vendor/autoload.php';
+
+use Facturapi\Facturapi;
+
+$apiKey = getenv('FACTURAPI_KEY') ?: 'YOUR_API_KEY';
+$facturapi = new Facturapi($apiKey);
+
+$customer = $facturapi->Customers->create([
+  'email' => 'walterwhite@gmail.com',
+  'legal_name' => 'Walter White',
+  'tax_id' => 'WIWA761018',
+  'address' => [
+    'zip' => '06800',
+    'street' => 'Av. de los Rosales',
+    'exterior' => '123',
+    'neighborhood' => 'Tepito',
+  ],
+]);
+```
+
+## Configuración del Cliente ⚙️
+
+Firma del constructor:
+
+```php
+new Facturapi(string $apiKey, ?array $config = null)
+```
+
+Claves soportadas en `config`:
+- `apiVersion` (`string`, valor por defecto: `v2`)
+- `timeout` (`int|float`, valor por defecto: `360` segundos)
+- `httpClient` (`Psr\Http\Client\ClientInterface`, avanzado)
+
+Ejemplo:
+
+```php
+use Facturapi\Facturapi;
+
+$facturapi = new Facturapi($apiKey, [
+  'apiVersion' => 'v2',
+  'timeout' => 420,
+]);
+```
+
+### Cliente HTTP Personalizado (Avanzado)
+
+El SDK funciona sin configuración adicional con su cliente interno basado en Guzzle.
+
+Si proporcionas `httpClient`, puedes pasar cualquier cliente compatible con PSR-18 y configurar ahí mismo los timeouts:
+
+```php
+use Facturapi\Facturapi;
+use GuzzleHttp\Client;
+
+$httpClient = new Client([
+  'timeout' => 420,
+]);
+
+$facturapi = new Facturapi($apiKey, [
+  'httpClient' => $httpClient,
+]);
+```
+
+## Uso Común 🧾
+
+### Crear un Producto
+
+```php
+$product = $facturapi->Products->create([
+  'product_key' => '4319150114',
+  'description' => 'Apple iPhone 8',
+  'price' => 345.60,
+]);
+```
+
+### Crear una Factura
+
+```php
+$invoice = $facturapi->Invoices->create([
+  'customer' => 'YOUR_CUSTOMER_ID',
+  'items' => [[
+    'quantity' => 1,
+    'product' => 'YOUR_PRODUCT_ID',
+  ]],
+  'payment_form' => \Facturapi\PaymentForm::EFECTIVO,
+  'folio_number' => '581',
+  'series' => 'F',
+]);
+```
+
+### Descargar Archivos
+
+```php
+$zipBytes = $facturapi->Invoices->downloadZip('INVOICE_ID');
+$pdfBytes = $facturapi->Invoices->downloadPdf('INVOICE_ID');
+$xmlBytes = $facturapi->Invoices->downloadXml('INVOICE_ID');
+```
+
+`downloadPdf()` devuelve bytes crudos de PDF (cadena binaria), no base64.
+
+```php
+file_put_contents('invoice.pdf', $pdfBytes);
+```
+
+### Enviar por Correo
+
+```php
+$facturapi->Invoices->sendByEmail('INVOICE_ID');
+```
+
+### Catálogos de Comercio Exterior
+
+```php
+$results = $facturapi->ComercioExteriorCatalogs->searchTariffFractions([
+  'q' => '0101',
+  'page' => 0,
+  'limit' => 10,
+]);
+```
+
+## Manejo de Errores ⚠️
+
+En respuestas no-2xx, el SDK lanza `Facturapi\Exceptions\FacturapiException`.
+
+La excepción incluye:
+- `getMessage()`: mensaje del API cuando está disponible.
+- `getStatusCode()`: código HTTP.
+- `getErrorData()`: payload JSON decodificado del error (shape completo del API).
+- `getRawBody()`: cuerpo crudo de la respuesta.
+
+```php
+use Facturapi\Exceptions\FacturapiException;
+
+try {
+  $facturapi->Invoices->create($payload);
+} catch (FacturapiException $e) {
+  $status = $e->getStatusCode();
+  $error = $e->getErrorData(); // Shape completo del error del API cuando el body es JSON válido.
+  $firstDetail = $error['details'][0] ?? null; // p.ej. ['path' => 'items.0.quantity', 'message' => '...', 'code' => '...']
+}
+```
+
+## Notas de Migración (v4) 🔄
+
+- La versión mínima de PHP ahora es `>=8.2`.
+- Se eliminó el soporte para el argumento posicional `apiVersion` en el constructor.
+- Proyectos con Composer: no requieren cambios de carga; continúen usando `vendor/autoload.php`.
+- Proyectos sin Composer pueden seguir usando el SDK cargando `src/Facturapi.php` directamente.
+- Los aliases snake_case están deprecados en v4 y se eliminarán en v5.
+- `Facturapi\\Exceptions\\Facturapi_Exception` está deprecada en v4 y se eliminará en v5.
+- Usa `Facturapi\\Exceptions\\FacturapiException`.
