When running a high-volume Telegram bot in Laravel—such as an automated customer booking bot or localized order notification system—blindly accepting incoming HTTP requests on a public controller route exposes your application to spoofed hits, database duplication, and cascading worker timeouts.

Telegram's webhook architecture operates under strict execution rules. When Telegram sends an Update object to your server, it expects an HTTP 200 OK response almost instantly. If your server takes longer than a few seconds due to database transactions, third-party API calls, or email dispatching, Telegram considers the delivery attempt a failure. It will abort the connection and retry the exact same update repeatedly.
