title: Allow other services to post in my twitter acoount
body: <p>Some of my customers want to use my bot that will automatically post some content in their twitter account.</p>
  <p>I have an elevated twitter dev account.</p>
  <p>Do my customers also need an elevated twitter dev account and I need to use their api keys in order to post in their accounts or is there another way in which they authrize my bot to post in their twitter accounts without the need to create dev accounts?</p>
