+### Notifications
+Ozon can send push-notifications to your REST server. There is an implementation of REST server that handles notifications in this library.
+
+[Official documentation](https://docs.ozon.ru/api/seller/en/#tag/push_intro)
+
+How to use:
+```Golang
+package main
+

+
+	"github.com/diphantxm/ozon-api-client/ozon/notifications"
+)
+
+func main() {

+	// Register handlers passing message type and handler itself
+	server.Register(notifications.ChatClosedType, func(req interface{}) error {
+		notification := req.(*notifications.ChatClosed)
+
+		// Do something with the notification here...

+	})
+
+	// Run server
