Os exemplos de código a seguir, que usam a biblioteca de cliente de APIs do Google para Ruby, estão disponíveis para YouTube Data API. Você pode fazer o download desses exemplos de código na pasta ruby do repositório de exemplos de código das APIs do YouTube no GitHub (link em inglês).
Adicionar uma inscrição de canal
Este exemplo chama o método subscriptions.insert da API para adicionar uma assinatura para um canal específico.

Autorizar uma solicitação
O exemplo de código a seguir executa a autorização OAuth 2.0 verificando a presença de um que contém as credenciais de autorização. Se o arquivo não estiver presente, o script abrirá um navegador e aguardará para uma resposta e salva localmente as credenciais retornadas.

Recuperar meus envios
Este exemplo chama o método playlistItems.list da API para recuperar uma lista de vídeos enviados ao canal associado à solicitação. O código também chama o método channels.list com a O parâmetro mine é definido como true para recuperar o ID da playlist que identifica o vídeos enviados.
