TL;DR

• Polling for real-time crypto updates consumes API credits, introduces latency, and repeatedly checks for changes. Crypto webhooks replace that loop with event-driven delivery, sending updates only when a relevant event occurs.

• CoinGecko’s cg.coin.info.updated webhook pushes coin metadata changes such as contract migrations, symbol and logo updates, category changes, and public notices directly to your endpoint, keeping swap interfaces, security alerts, and portfolio trackers in sync.
