Summary
This article explains how webhooks provide a more efficient alternative to polling for real-time cryptocurrency data updates. It contrasts polling's limitations (fixed schedules, wasted requests, latency, server overhead) with webhooks' event-driven push delivery model. The guide focuses on CoinGecko's webhook implementation for delivering real-time crypto updates like coin metadata changes, price-threshold alerts, and newly indexed token events, ultimately reducing API costs and operational overhead as applications scale.

With webhooks, it removes friction through event-driven push delivery
