I am really confuse because i saw i can generate an Acces token at https://apps.twitter.com. But does this Acces token will work for posting tweet for all user that login in my application ?
No. That access token is specifically for the Twitter user that is currently logged into Twitter (AKA the owner of the application).
Thank you for your reply and is this the way to get Acces token for my user https://developer.twitter.com/en/docs/basics/authentication/guides/authorizing-a-request?
