+## Установка
+
+```bash
+composer require apoloz/alfa-bank-sdk
+```
+
+## Подготовка сертификатов (mTLS)
+
+Взаимодействие с API Альфа-Банка требует двухстороннего TLS-соединения. Банк не выдает закрытый ключ, вы должны сгенерировать его самостоятельно.
+
+**1. Генерация закрытого ключа и запроса (CSR):**
+Используйте OpenSSL для создания ключа и файла запроса. Создайте файл `openssl.cnf`:
+```ini
+[req]
+distinguished_name = req_distinguished_name
+prompt = no
+[req_distinguished_name]
+C = RU
+L = Moscow
+O = Название Вашей Компании
+CN = ФИО Ответственного
+emailAddress = your_email@company.com
+1.2.643.100.4 = 1234567890 (Ваш ИНН)
+```
+
+Выполните команды в терминале:
+```bash
+# Генерация закрытого ключа (храните его в секрете!)
+openssl genrsa -out private.key 2048
+
+# Генерация запроса на сертификат
+openssl req -new -key private.key -out request.csr -config openssl.cnf -utf8
+```
+
+**2. Отправка в Банк:**
+Отправьте файл `request.csr` на почту `alfa_api@alfabank.ru`. В ответ банк пришлет публичный сертификат (`client.cer` или `client.crt`).
+
+**3. Использование:**
+Поместите полученный сертификат и ваш закрытый ключ в надежное место и укажите пути к ним в `.env` (переменные `ALFA_BAAS_CERT_PATH` и `ALFA_BAAS_KEY_PATH`).
+
+## 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
+# URL в вашем приложении, на который вернется пользователь после входа (должен совпадать с настройками в Портале)
+ALFA_BAAS_REDIRECT_URI=https://your-app.com/alfa/callback
+ALFA_BAAS_CERT_PATH=storage/certs/baas_cert.pem
+ALFA_BAAS_KEY_PATH=storage/certs/baas_key.pem
+# Путь к корневым сертификатам (или 'false' для отключения проверки SSL в sandbox)
+ALFA_BAAS_CA_BUNDLE=false 
+
+# 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
+ALFA_SBP_CA_BUNDLE=false
+
+# --- 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

+    'baas' => [
+        'environment' => env('ALFA_BAAS_ENVIRONMENT', 'sandbox'),

+### 3. Авторизация Authorization Code Flow (H2H)
+
+SDK использует нативный функционал Saloon для OAuth2.
+
+**1. Инициализация:**
+```php
+$baas = AlfaBank::baas(
+    clientId: '...', clientSecret: '...', redirectUri: '...',
+    certificatePath: '...', privateKeyPath: '...'
+);
+```
+
+**2. Получение ссылки на вход:**
+```php
+$url = $baas->getAuthorizationUrl(['beneficiaries']);
+// Перенаправьте пользователя на $url
+```
+
+**3. Обмен кода на токен:**
+```php
+$authenticator = $baas->getAccessToken($code);
+$baas->authenticate($authenticator); // Применить токен
+// Сохраните $authenticator->getRefreshToken() в БД
+```
+
+**4. Обновление токена:**
+```php
+$newAuth = $baas->refreshAccessToken($savedRefreshToken);
+$baas->authenticate($newAuth);
+```
+
+**Пример обработки callback в Laravel:**
+```php
+// routes/web.php
+Route::get('/alfa/callback', function (Request $request, AlfaBankConnector $baas) {
+    $code = $request->query('code');
+    
+    // Обмениваем временный код на постоянные токены
+    $authenticator = $baas->getAccessToken($code);
+    
+    // Сохраняем refresh_token в БД для будущих обновлений сессии
+    $refreshToken = $authenticator->getRefreshToken();
+    auth()->user()->update(['alfa_refresh_token' => $refreshToken]);
+
+    return "Авторизация в Альфа-Банке прошла успешно!";
+});
+```
+
+Полный пример: [examples/13_h2h_auth_service.php](examples/13_h2h_auth_service.php)
+
+### 4. Генерация Client Secret (Утилита)
+Если банк выдал только сертификаты, вы можете сгенерировать `client_secret` самостоятельно:
+```php
+// См. examples/14_generate_client_secret.php
+$baas->send(new RefreshClientSecretRequest($clientId));
+```
+
+> **Важно для продакшена:**
+> Запрос нового секрета **инвалидирует** старый. Если у вас запущено несколько экземпляров приложения (или worker-ов), не запрашивайте секрет при каждом старте.
+> **Решение:** Получите секрет один раз, сохраните в общий кеш (Redis/DB) с TTL (например, 29 дней) и запрашивайте новый только при истечении срока или отсутствии в кеше.
+> Полный пример автоматизации: [examples/16_automated_startup.php](examples/16_automated_startup.php)

+# Alfa Bank SDK Examples
+
+This directory contains executable PHP scripts demonstrating various features of the SDK.
+
+## How to Run
+
+### 1. Standalone (CLI)
+You can run any script directly from the terminal if you have PHP installed.
+Ensure you have run `composer install` in the SDK root first.
+
+```bash
+cd alfa-bank-sdk
+php examples/01_baas_flow.php
+```
+
+### 2. Laravel Tinker
+Most examples are designed to be copy-paste friendly for `php artisan tinker`.
+
+**General Steps:**
+1. Open your Laravel project terminal.
+2. Run `php artisan tinker`.
+3. Instead of the manual `AlfaBank::baas(...)` initialization, use the Laravel helper:
+   ```php
+   $baas = app(\Apoloz\AlfaBank\Core\AlfaBankConnector::class);
+   $baas->login(); // Or refresh token
+   ```
+4. Copy the rest of the logic (DTO creation, signing, sending) from the example file.
+
+**Dedicated Tinker Workflow:**
+See `17_laravel_tinker_scoring_creation.php` for a complete, copy-paste ready workflow for creating beneficiaries.
+
+## Key Examples
+
+- **01_baas_flow.php**: Basic setup and connection check.
+- **13_h2h_auth_service.php**: How to get your first OAuth token.
+- **14_generate_client_secret.php**: If you lost your Client Secret.
+- **15_nominal_accounts_list.php**: Fetching lists (Beneficiaries).
+- **17_laravel_tinker_scoring_creation.php**: **START HERE** for Nominal Accounts integration.
