The most likely answer is that you need to buy the ticket for The International / Dota 2 event through the official sale page, and for some events you may also need an early access code from eligible Dota purchases or subscriptions. For older Dota 2 league-style tickets, Steam Support says you sign up on the league page and get redirected to the league admin to complete it.

How it works

  • For The International tickets, official sales are handled through the event’s ticketing partner, and tickets can sell out fast.
  • Some ticket windows give early access to players who owned Battle Pass or Dota Plus at the qualifying time.
  • If you’re asking about a league ticket in Dota TV, you usually register through the league sign-up flow first.

Practical steps

  1. Check the official Dota 2 event announcement for the sale date and ticketing link.
  1. Make sure your account is ready before sales open.
  1. If the event offers early access, verify whether you qualify through Battle Pass or Dota Plus status.
  1. Buy only from the official seller to avoid reseller markups.

If you mean “The Stars”

Your phrase looks incomplete, so I treated it as a Dota 2 ticket question. If “The Stars” is the name of a specific team, event, or community tournament, the buying process could be different and may use a league signup page instead.
