FAQ
What are Blockchain Webhooks and how do they work?
Blockchain Webhooks are automated HTTP callbacks that monitor tracked blockchain addresses and send a POST request to your server when a balance update occurs. Instead of maintaining a constant connection, the system checks blockchain data internally and triggers delivery only when changes happen.
How are Blockchain Webhooks different from WebSocket connections?
WebSockets require a persistent WSS connection and push events in real time, but delivery isn’t guaranteed if the connection drops. Webhooks, on the other hand, send HTTP requests only when balance changes occur and retry until they receive a 200 OK response, ensuring higher delivery reliability.
What blockchain events can Webhooks track?
Current Webhooks track balance updates for specified addresses. They are not customizable for other event types like new blocks or specific transaction filters.
How do you set up a Blockchain Webhook?
You create a Webhook in your dashboard by selecting a network and adding the addresses you want to monitor. You then provide a destination URL where notifications will be delivered. A test notification can be sent before activation to verify integration.
