League Setup

Connect your Sleeper league

Search by username or paste a public league ID. No Sleeper login required.

Sleeper league connection

Connect your league

Search by Sleeper username or paste a public league ID. Sunday Signal uses league settings, roster, scoring, and draft context to power the real Draft Room.

What you need

A public Sleeper league

Use username search if you know your Sleeper account. Use league ID if you have the league URL open.

  1. 1. Find the ID in a Sleeper league URL after /league/.
  2. 2. Pick your roster so Sunday Signal can read team needs.
  3. 3. Continue to Draft Room with your real scoring and draft board.

Safe boundary

No Sleeper login is required. Sunday Signal only reads public league, roster, draft, and scoring context.

Find leagues by username

Best if your leagues are public and you know your Sleeper account name.

Paste league ID

In Sleeper, open the league and copy the number after /league/.
