Real-time on-chain data is the key to unlocking everything from trading bots to live dashboards, but with current data products, you're often stuck sacrificing speed, quality of data, or ease of setup. Today we’re changing that. Webhooks lets you go from zero to live blockchain data in seconds.

什么是Webhooks？

Quicknode Webhooks is a serverless, pay-per-match data alerts tool that pushes real-time blockchain events directly to your HTTP endpoint. It allows you to filter on-chain data with JavaScript or prebuilt templates, subscribe in seconds, and pay only when your filter actually matches.

Why Webhooks are the right choice for easy real-time data

• Go live in seconds
  Pick a template (contract events, token transfers) or paste your custom JS filter, enter your URL, and hit Create. Your Webhook is live in less than 60 seconds.

• Push-based delivery
  No polling, no queues. Matching blocks and events fire off to your endpoint the moment they occur, so you never miss a beat.

• Exactly-once & reorg-safe
  Every payload is retried until delivered and reordered correctly after chain reorganizations, so your app sees each event exactly once, in order.

• 90+ networks, one interface
  Set up Webhooks for Ethereum, Solana, Avalanche, Arbitrum, and more, all under one roof.

• Pay-per-match pricing
  Only pay credits when your filter delivers a payload. Empty blocks or non-matching events cost you nothing.

What apps and workflows can benefit the most from Webhooks?

• Trading Bots & Automation: Trigger strategies on specific token swaps or DeFi events in real time.

• Wallet & Smart Contract Monitoring: Track wallet balances, token approvals, and contract events as they happen.

• Alerts & Notifications: Power Telegram or Discord bots to notify communities of big transfers, DAO moves, or rare mints.

• Analytics Pipelines: Get live filtered transactions directly into your data warehouse—no batch lag, no wasted credits.
