Telegram bots that receive updates via webhook need to be both secure and idempotent. A lead‑generation Mini App, for example, sends a JSON payload with the user’s contact details to your Laravel endpoint. If you accept the request blindly, an attacker can replay the same update or forge a request…

Designing retry-safe financial operations across clients, workers, databases, and external providers. Payment clients retry requests. Load balancers retry requests. Background workers retry tasks. Users press a button again when the screen appears stuck. Providers may time out after accepting an…
For NestJS production error tracking, use one normalized failure envelope at every execution boundary, then measure latency and estimated cost separately from exceptions. An HTTP filter and interceptor cover only the request path; a media AI agent loop also needs explicit capture around scheduled…
