I would like to know how to request access permission for membership API.I am wondering where I should inquire to gain access permission.
Tried to make this request on OAuth 2.0 Playground and always got the same response.Doc says that I must contact my youtube representative but I don't know where.
{"error": {"message": "Access forbidden. The request may not be properly authorized.", "code": 403, "errors": [ {"reason": "forbidden", "message": "Access forbidden. The request may not be properly authorized.", "domain": "youtube.common" } ] }}
