+### 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
+
+import (
+	"log"
+
+	"github.com/diphantxm/ozon-api-client/ozon/notifications"
+)
+
+func main() {
+	// Create server
+	port := 5000
+	server := notifications.NewNotificationServer(port)
+
+	// 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...
+		log.Printf("chat %s has been closed\n", notification.ChatId)
+
+		return nil
+	})
+
+	// Run server
+	if err := server.Run(); err != nil {
+		log.Printf("error while running notification server: %s", err)

+}
+```

 If you need some endpoints ASAP, create an issue and list all the endpoints. I will add them to library soon.
