I am working on a script , and i need to check if a user has already subscribed to my youtube channel, is there any API call or any script to check if the user already subscribed or not ? Any type of help/hint will be heartly appreciated :)
Yes,youtube Api can help you,follow this link: https://developers.google.com/youtube/2.0/developers_guide_protocol#Saving_and_collecting_videos
But I'm not sure it need user authorization or not.
Sorry,wrong link,follow this: https://developers.google.com/youtube/2.0/developers_guide_protocol#Retrieving_subscriptions
the api just like
https://gdata.youtube.com/feeds/api/users/userId/subscriptions?v=2
You can get a user's subscriptions,then you can check your channel is in it or not. This request does not require authentication.
