إعداد المصادقة

عند استخدام مكتبات برامج، عليك استخدام بيانات الاعتماد التلقائية للتطبيق (ADC) لإجراء المصادقة. للحصول على معلومات حول إعداد ADC، يُرجى الاطّلاع على توفير بيانات الاعتماد لـ "بيانات الاعتماد التلقائية للتطبيق". للحصول على معلومات حول استخدام ADC مع مكتبات البرامج، راجِع مقالة المصادقة باستخدام مكتبات البرامج.
