Thank you, brandonmblack.
I not use @vodinhtoan twitter account.
I use another account for development @aerobeacon.
This account has developer access level(Ads API).
Please check app_id 8346565.
Both app, and twurl have same error: {“code”:“UNAUTHORIZED_CLIENT_APPLICATION”,“message”:“The client application making this request does not have access to this API”}
Please help me check for my app_id problem. I can’t did anything last week. Many thanhk for your hep.
