+# Address processing
+
+С версии `4.3.8` изменена логика работы с адресами.
+
+В заказ CRM c заказа WooCommerce будет передаваться, только shipping адрес. Если при оформлении заказа указан только billing адрес, то WooCommerce записывает в БД эти же данные в shipping, то есть shipping = billing.
+
+При создании обычных/корпоративных клиентов в CRM будет передаваться billing адрес с заказа/пользователя WooCommerce. Если клиент гость и у него нет данных по billing адресу, тогда будет передан billing адрес заказа.
+
+Для кастомизаций адресов в CRM, добавили новые фильтры:
+* `retailcrm_process_order_address`
+* `retailcrm_process_customer_address`
+* `retailcrm_process_customer_corporate_address`
+
+## Пример работы фильтров
+В приведенном ниже примере показано, как возможно кастомизировать адрес заказа:
+
+```php
+<?php
+
+add_filter('retailcrm_process_order_address', 'editOrderAddress', 10, 2);
+
+function editOrderAddress($address, $order)
+{
+    $address['text'] = 'Test';
+    
+    return $address;
+}
+```
