View Fantasy Football Rosters via Telegram & Sleeper API

This n8n workflow powers a Telegram chatbot that lets fantasy football users instantly view their Sleeper roster by sending their username. It extracts the username, fetches the Sleeper User ID, retrieves leagues (defaulting to the first), pulls league rosters, identifies the user's team, maps player_ids to full details (names, positions, teams) from a database like Airtable or Google Sheets, and sends a formatted response back to Telegram.

Benefits include seamless, app-free roster checks during games or drafts, reducing time spent navigating Sleeper's interface. It's highly useful for in-season monitoring, trade evaluations, or casual league chats, saving users minutes per query and enabling conversational automation.

Ideal use cases: Quick roster lookups for managers in multiple leagues, pre-draft player reviews, or integrating with daily player sync workflows for real-time data. Customization options allow league selection logic or multi-league support.

Setup is straightforward: Import into n8n, configure Telegram bot credentials and database (e.g., Airtable), and pair with a player database sync template. No coding required for basic use.
