What are Webhooks?
Webhooks in the web3 context are tools and services that enable real-time event notifications from blockchain networks or related infrastructure to external applications. These tools listen for specific on-chain events, such as transactions, contract state changes, or token transfers, and send HTTP callbacks to developers' endpoints when those events occur. This allows applications to react immediately without continuously polling the blockchain.
Tools in this category typically include webhook providers integrated with blockchain nodes, smart contract event listeners, and notification services that support filtering and custom triggers. Primary users are developers building dapps, wallets, analytics platforms, or any system requiring timely updates from blockchain activity. Key characteristics include reliability, low latency, event filtering, and secure delivery of payloads.
Webhooks often complement monitoring and infrastructure services by providing push-based event delivery rather than pull-based data retrieval. Related categories include blockchain infrastructure providers and monitoring tools. Developers should consider webhook tools when they need efficient, scalable, and automated ways to respond to blockchain events in real time without managing complex polling logic.
