How to Secure and Deduplicate Telegram Webhooks in Laravel Using Redis

A Laravel tutorial outlines how to build a production-ready Telegram webhook ingestion pipeline that handles duplicate updates and slow processing. The approach uses a custom middleware to validate Telegram's secret token header, ensuring only legitimate requests reach the application. Incoming payloads are immediately dispatched to a queued job and a 200 OK response is returned, preventing Telegram from timing out and resending updates. Redis is used to enforce idempotency by storing processed update IDs with a 24-hour expiry, using atomic SET NX operations to block duplicate processing. The guide focuses strictly on the webhook ingestion layer and does not cover full bot framework setup or worker daemon management.
