Delphi ile Youtube data API işlemleri
Merhabalar,
Youtube’un bize sağladığı apileri Delphi uygulaması ile nasıl kullanabiliriz (in) cevabı bu yazıda olacak.
Öncelikle Buradaki youtube developer sitesinden bir api key edinmeniz gerekiyor.
Api keyinizi aldıktan sonra aşağıdaki hazırladığımUV3 .pas dosyasını inceleyebilirsiniz. nerede ne yaptığımı uzun uzun anlatmaya zamanım yok ancak sorunuz olur ise aşağıdan sorabilirsiniz.
