I am trying to use youtube api to get a list of subscribers to my own channel, and then check the user’s email to see if he is signed or not. Now I use this page to check my first step https://developers.google.com/youtube/v3/docs/subscriptions/list and insert the data as follows, and all other fields are empty
As you can see, I get this error, and the part label contains an error, and the value is a snippet. how to solve this problem, and if it is resolved as necessary, will it be available to receive a list of all the addresses of users subscribed to my channel in the form of a list?
