+Integration tests run in GitHub actions with real Bitrix24 portal
+
+## BITRIX24-PHP-SDK ✨FEATURES✨
+
+Support both auth modes:
+
+- [x] work with auth tokens for Bitrix24 applications in marketplace
+- [x] work with incoming webhooks for simple integration projects for current portal
+
+Domain core events:
+
+- [x] Access Token expired
+- [x] Bitrix24 portal domain url changed
 
-A powerfull PHP library for the Bitrix24 REST API
+API - level features
 
-[Bitrix24 API documentation - Russian](http://dev.1c-bitrix.ru/rest_help/)<br />
-[Bitrix24 API documentation - English](https://training.bitrix24.com/rest_help/)
-## Promo code for new Bitrix24 accounts 
-- `b24io5gb` — add 5GB on your Bitrix24
-- `b24iousers`  — add 12 users on your Bitrix24  
+- [x] Auto renew access tokens
+- [x] List queries with «start=-1» support
+- [ ] offline queues
 
-[Register new Bitrix24 account](https://www.bitrix24.ru/create.php?p=255670)
+Performance improvements 🚀
+
+- [x] Batch queries implemented with [PHP Generators](https://www.php.net/manual/en/language.generators.overview.php) –
+  constant low memory and low CPI usage:
+- [x] batch read data from bitrix24
+- [x] batch write data to bitrix24
+- [x] read without count flag
+
+## Development principles
+
+- Good developer experience
+    - auto-completion of methods at the IDE
+    - typed method call signatures
+    - typed results of method calls
+    - helpers for typical operations
+- Good documentation
+    - documentation on the operation of a specific method containing a link to the official documentation
+    - documentation for working with the SDK
+- Performance first:
+    - minimal impact on client code
+    - ability to work with large amounts of data with constant memory consumption
+    - efficient operation of the API using batch requests
+- Modern technology stack
+    - based on [Symfony HttpClient](https://symfony.com/doc/current/http_client.html)
+    - actual PHP versions language features
+- Reliable:
+    - test coverage: unit, integration, contract
+    - typical examples typical for different modes of operation and they are optimized for memory \ performance
+
+## Architecture
+
+### Abstraction layers
+
+```
+- http2 protocol via json data structures
+- symfony http client
+- \Bitrix24\SDK\Core\ApiClient - work with b24 rest-api endpoints
+    input: arrays \ strings
+    output: Symfony\Contracts\HttpClient\ResponseInterface, operate with strings
+    process: network operations 
+- \Bitrix24\SDK\Services\* - work with b24 rest-api entities
+    input: arrays \ strings
+    output: b24 response dto
+    process: b24 entities, operate with immutable objects  
+```
+
+## Documentation
+

-<?php
+## Installation
+
+Add `"mesilov/bitrix24-php-sdk": "2.x"` to `composer.json` of your application. Or clone repo to your project.
+
+## Examples
+
+### Work with webhook
+
+1. Go to `/examples/webhook` folder
+2. Open console and install dependencies
+
+```shell
+composer install
+```
+
+3. Open Bitrix24 portal: Developer resources → Other → Inbound webhook
+4. Open example file and insert webhook url into `$webhookUrl`
+
+<details>
+  <summary>see example.php file</summary>
+
+```php
+declare(strict_types=1);
+
+use Bitrix24\SDK\Services\ServiceBuilderFactory;
+use Symfony\Component\EventDispatcher\EventDispatcher;
 use Monolog\Logger;
 use Monolog\Handler\StreamHandler;
+use Monolog\Processor\MemoryUsageProcessor;
+
+require_once 'vendor/autoload.php';
+
+$webhookUrl = 'INSERT_HERE_YOUR_WEBHOOK_URL';
+
+$log = new Logger('bitrix24-php-sdk');
+$log->pushHandler(new StreamHandler('bitrix24-php-sdk.log'));
+$log->pushProcessor(new MemoryUsageProcessor(true, true));
+
+// create service builder factory
+$b24ServiceFactory = new ServiceBuilderFactory(new EventDispatcher(), $log);
+// init bitrix24-php-sdk service from webhook
+$b24Service = $b24ServiceFactory->initFromWebhook($webhookUrl);
+
+// work with interested scope
+var_dump($b24Service->getMainScope()->main()->getCurrentUserProfile()->getUserProfile());
+// get deals list and address to first element
+var_dump($b24Service->getCRMScope()->lead()->list([], [], ['ID', 'TITLE'])->getLeads()[0]->TITLE);
+```
+
+</details>
+
+5. Call php file in shell
+
+```shell
+php -f example.php
+```
+
+### Work with local application
+
+1. Go to `/examples/local-application` folder
+2. Open console and install dependencies
+
+```shell
+composer install
+```
+
+3. Start local development server
+
+```shell
+sudo php -S 127.0.0.1:80
+```
+
+4. Expose local server to public via [ngrok](https://ngrok.com/) and remember temporally public url –
+   `https://****.ngrok-free.app`
+
+```shell
+ngrok http 127.0.0.1
+```
+
+5. Check public url from ngrok and see `x-powered-by` header with **200** status-code.
+
+```shell
+curl https://****.ngrok-free.app -I
+HTTP/2 200 
+content-type: text/html; charset=UTF-8
+date: Mon, 26 Aug 2024 19:09:24 GMT
+host: ****.ngrok-free.app
+x-powered-by: PHP/8.3.8
+```
+
+6. Open Bitrix24 portal: Developer resources → Other → Local application and create new local application:
+   - `type`: server
+   - `handler path`: `https://****.ngrok-free.app/index.php`
+   - `Initial installation path`: `https://****.ngrok-free.app/install.php`
+   - `Menu item text`: `Test local app`
+   - `scope`: `crm`
+7. Save application parameters in `index.php` file: 
+   - `Application ID (client_id)` — `BITRIX24_PHP_SDK_APPLICATION_CLIENT_ID` 
+   - `Application key (client_secret)` — `BITRIX24_PHP_SDK_APPLICATION_CLIENT_SECRET` 
+   - `Assing permitions (scope)` — `BITRIX24_PHP_SDK_APPLICATION_SCOPE`
+<details>
+  <summary>see index.php file</summary>
+
+```php
+declare(strict_types=1);
+
+use Bitrix24\SDK\Core\Credentials\AuthToken;
+use Bitrix24\SDK\Core\Credentials\ApplicationProfile;
+use Bitrix24\SDK\Services\ServiceBuilderFactory;
+use Monolog\Handler\StreamHandler;
+use Monolog\Logger;
+use Monolog\Processor\MemoryUsageProcessor;
+use Symfony\Component\EventDispatcher\EventDispatcher;
+use Symfony\Component\HttpFoundation\Request;
+
+require_once 'vendor/autoload.php';
+?>
+    <pre>
+    Application is worked, auth tokens from bitrix24:
+    <?= print_r($_REQUEST, true) ?>
+</pre>
+<?php
+$request = Request::createFromGlobals();
+
+$log = new Logger('bitrix24-php-sdk');
+$log->pushHandler(new StreamHandler('bitrix24-php-sdk.log'));
+$log->pushProcessor(new MemoryUsageProcessor(true, true));
+
+$b24ServiceBuilderFactory = new ServiceBuilderFactory(new EventDispatcher(), $log);
+$appProfile = ApplicationProfile::initFromArray([
+    'BITRIX24_PHP_SDK_APPLICATION_CLIENT_ID' => 'INSERT_HERE_YOUR_DATA',
+    'BITRIX24_PHP_SDK_APPLICATION_CLIENT_SECRET' => 'INSERT_HERE_YOUR_DATA',
+    'BITRIX24_PHP_SDK_APPLICATION_SCOPE' => 'INSERT_HERE_YOUR_DATA'
+]);
+$b24Service = $b24ServiceBuilderFactory->initFromRequest($appProfile, AuthToken::initFromPlacementRequest($request), $request->get('DOMAIN'));
+
+var_dump($b24Service->getMainScope()->main()->getCurrentUserProfile()->getUserProfile());
+// get deals list and address to first element
+var_dump($b24Service->getCRMScope()->lead()->list([], [], ['ID', 'TITLE'])->getLeads()[0]->TITLE);
+```
+
+</details>
+8. Save local application in Bitrix24 tab and press «OPEN APPLICATION» button.    
+
+
+### Create application for Bitrix24 marketplace
+
+if you want to create application you can use production-ready contracts in namespace
+`Bitrix24\SDK\Application\Contracts`:
+
+- `Bitrix24Accounts` — Store auth tokens and
+  provides [methods](src/Application/Contracts/Bitrix24Accounts/Docs/Bitrix24Accounts.md) for work with Bitrix24
+  account.
+- `ApplicationInstallations` — Store information
+  about [application installation](src/Application/Contracts/ApplicationInstallations/Docs/ApplicationInstallations.md),
+  linked with Bitrix24 Account with auth
+  tokens. Optional can store links to:
+    - Client contact person: client person who responsible for application usage
+    - Bitrix24 Partner contact person: partner contact person who supports client and configure application
+    - Bitrix24 Partner: partner who supports client portal
+- `ContactPersons` – Store information [about person](src/Application/Contracts/ContactPersons/Docs/ContactPersons.md)
+  who installed application.
+- `Bitrix24Partners` – Store information
+  about [Bitrix24 Partner](src/Application/Contracts/Bitrix24Partners/Docs/Bitrix24Partners.md) who supports client
+  portal and install or configure application.
+
+Steps:
+
+1. Create own entity of this bounded contexts.
+2. Implement all methods in contract interfaces.
+3. Test own implementation behavior with contract-tests `tests/Unit/Application/Contracts/*` – examples.
+
+## Tests
 
-// create a log channel
-$log = new Logger('bitrix24');
-$log->pushHandler(new StreamHandler('path/to/your.log', Logger::DEBUG));
+Tests locate in folder `tests` and we have two test types.
+In folder tests create file `.env.local` and fill environment variables from `.env`.
 
+### PHP Static Analysis Tool – phpstan
 
-// init lib
-$obB24App = new \Bitrix24\Bitrix24(false, $log);
-$obB24App->setApplicationScope($arParams['B24_APPLICATION_SCOPE']);
-$obB24App->setApplicationId($arParams['B24_APPLICATION_ID']);
-$obB24App->setApplicationSecret($arParams['B24_APPLICATION_SECRET']);
- 
-// set user-specific settings
-$obB24App->setDomain($arParams['DOMAIN']);
-$obB24App->setMemberId($arParams['MEMBER_ID']);
-$obB24App->setAccessToken($arParams['AUTH_ID']);
-$obB24App->setRefreshToken($arParams['REFRESH_ID']);
+Call in command line
 
-// get information about current user from bitrix24
-$obB24User = new \Bitrix24\User\User($obB24App);
-$arCurrentB24User = $obB24User->current();
+```shell
+make lint-phpstan
+```
+
+### PHP Static Analysis Tool – rector
+
+Call in command line for validate
+
+```shell
+make lint-rector
+```
+
+Call in command line for fix codebase
+
+```shell
+make lint-rector-fix
+```
+
+### Unit tests
+
+**Fast**, in-memory tests without a network I\O For run unit tests you must call in command line
+
+```shell
+make test-unit
+```
+
+### Integration tests
+
+**Slow** tests with full lifecycle with your **test** Bitrix24 portal via webhook.
+
+❗️Do not run integration tests with production portals
+
+For run integration test you must:
+
+1. Create new Bitrix24 portal for development tests.
+2. Go to left menu, click «Sitemap».
+3. Find menu item «Developer resources».
+4. Click on menu item «Other».
+5. Click on menu item «Inbound webhook».
+6. Assign all permisions with webhook and click «save» button.
+7. Create file `/tests/.env.local` with same settings, see comments in `/tests/.env` file.
+
+```yaml
+APP_ENV=dev
+BITRIX24_WEBHOOK=https:// your portal webhook url
+INTEGRATION_TEST_LOG_LEVEL=500
+```
+
+8. call in command line
+
+```shell
+make test-integration-core
+make test-integration-scope-telephony
+make test-integration-scope-workflows
+make test-integration-scope-user
 ```

+        //
+        // В потенциале для ускорения можно попытаться параллельно передвигаться по списку сущностей в два потока:
+        // с начала списка и с конца, продолжая получать страницы, пока ID в двух потоках не пересекутся.
