What are webhooks?
Webhooks allow your application to react to real-time events in your Fireblocks workspace, such as deposits, withdrawals, transaction status changes, and more, by delivering structured event data directly to your servers as they happen.
They are ideal for automating operational workflows, keeping systems in sync, and reducing the need for manual processes or inefficient polling.
Fireblocks webhooks are particularly useful for:
- Triggering internal workflows on deposit confirmations or transaction completions
- Integrating with external systems such as CRMs, compliance tools, or accounting platforms
- Creating custom alerts for specific event types
Instead of continuously polling Fireblocks APIs, webhooks provide a more scalable, responsive, and performant way to receive updates as soon as they occur.
Webhooks vs. polling
Polling APIs involves repeatedly asking Fireblocks, “Has anything changed yet?” This process can be inefficient, slow, and make it easy to miss critical updates.
Webhooks flip that model: instead of constantly checking, your system gets notified the moment something happens. This makes webhooks ideal for real-time use cases where speed, efficiency, and reliability matter.
With polling:
- You risk missing events that happen between requests
- You consume unnecessary API quota and system resources
- You often need to write extra logic to check for changes and handle duplicates
With webhooks:
- You get immediate, push-based updates as soon as events occur
- You can subscribe only to the event types you care about
- You reduce latency, improve performance, and simplify your integration
