Informationen zum Installieren und Verwenden der Clientbibliothek für die Live Stream API findest du unter Live Stream API-Clientbibliotheken. Weitere Informationen finden Sie in der C# API-Referenzdokumentation zur Live Stream API.

Damit du dich bei der Live Stream API authentifizieren kannst, musst du Standardanmeldedaten für Anwendungen einrichten. Weitere Informationen finden Sie unter Authentifizierung für eine lokale Entwicklungsumgebung einrichten.
