I have my own website (online service). I want to notify users of my service through various channels. Including Twitter. I was planning to implement the auto-posting feature in my Twitter feed. But I was refused to create an application and a developer account.

now there is no way to use API to publish tweets on your own behalf?

I. e. I have only two options:

  1. do not use Twitter for the convenience of my users
  2. add the same tweets only manually
