+## Доступ

+`APIKey` — это per-project Admin Key: поле «Admin Key» в настройках проекта
+в дашборде (app.rudder.build → проект → Settings). Ключ сам определяет
+проект, отдельный project ID не нужен. Храните его только на сервере —
+никогда не вшивайте в игровые клиенты.
 
 ## Usage

 client, err := rudder.New(rudder.Config{

-    ProjectID: "your-project-id",
