 Профессиональная PHP-библиотека для интеграции с API Альфа-Банка (BaaS и СБП). Построена на базе [Saloon v3](https://docs.saloon.dev) и [Spatie Laravel Data](https://spatie.be/docs/laravel-data).

+## Установка
+
+```bash
+composer require apoloz/alfa-bank-sdk
+```
+
+## Конфигурация (Laravel)
+
+Опубликуйте файл конфигурации:
+```bash
+php artisan vendor:publish --tag=alfa-bank-config
+```
+
+### Настройка `.env`
+
+Добавьте следующие переменные в ваш файл `.env`. Вам понадобятся сертификаты (PEM) и ключи.
+
+```dotenv
+# --- BaaS (Номинальные счета, Выплаты) ---
+ALFA_BAAS_ENVIRONMENT=sandbox # или production
+ALFA_BAAS_CLIENT_ID=your-client-id
+ALFA_BAAS_CLIENT_SECRET=your-client-secret
+ALFA_BAAS_CERT_PATH=storage/certs/baas_cert.pem
+ALFA_BAAS_KEY_PATH=storage/certs/baas_key.pem
+
+# Опционально: Ключи для CMS-подписи (если отличаются от транспортных)
+# ALFA_BAAS_SIGNING_CERT_PATH=storage/certs/sign_cert.pem
+# ALFA_BAAS_SIGNING_KEY_PATH=storage/certs/sign_key.pem
+
+# --- SBP (СБП, QR-коды) ---
+ALFA_SBP_ENVIRONMENT=sandbox # или production
+ALFA_SBP_ALIAS=your-key-name-alias
+ALFA_SBP_CERT_PATH=storage/certs/sbp_cert.pem
+ALFA_SBP_KEY_PATH=storage/certs/sbp_key.pem
+
+# --- Webhooks ---
+ALFA_WEBHOOK_USER=alfa
+ALFA_WEBHOOK_PASSWORD=secret
+# Для проверки JWS-подписи вебхуков (опционально)
+ALFA_WEBHOOK_PUBLIC_KEY=storage/certs/alfa_public_key.pem
+```
+
+### Файл конфигурации (`config/alfa-bank.php`)
+
+Вот как выглядит структура конфигурационного файла по умолчанию. Вы можете использовать его для тонкой настройки, например, чтобы задать пути динамически.
+
+```php
