# Webhook Signatures

> Verify webhook signatures to ensure callbacks originate from Caibo.

## Why verify

Webhook signatures protect you from spoofed callbacks.

## How to verify

1. Retrieve the signature header sent with the callback
2. Compute your own signature using the shared secret
3. Compare calculated vs received values
