JWT Webhook Token & Claims Validator
Inspect, decode, and verify JSON Web Token (JWT) authorization headers in inbound webhooks
Direct Answer / Tool Overview
SafeWebhook automatically detects and decodes JWT tokens in `Authorization: Bearer <token>` headers. View decoded headers, claims, expiration timestamps, and verify cryptographic RS256/HS256 signatures.
Key Capabilities & Benefits
Auto-decodes JWT Header, Payload, and Signature components
Validates expiration timestamps (exp) and clock skew in real-time
Verify asymmetric RS256 / ES256 and symmetric HS256 tokens
Zero server-side retention protects sensitive bearer tokens
How to Use: Step-by-Step Practical Guide
Follow these simple steps to configure and utilize this feature:
1
Send a request containing an Authorization: Bearer <JWT> header to SafeWebhook.
2
Click the request in your timeline and navigate to the "Headers" inspector.
3
SafeWebhook displays the decoded JSON claims and signature status.
4
Export the verification script to implement in your production gateway.
Code Configuration & Integration Recipe
cURL / JavaScript API// Node.js JWT Verification with jsonwebtoken
import jwt from 'jsonwebtoken';
export function verifyWebhookJwt(authHeader, publicKey) {
const token = authHeader.replace('Bearer ', '');
try {
const decoded = jwt.verify(token, publicKey, { algorithms: ['RS256'] });
console.log('Valid JWT Subject:', decoded.sub);
return decoded;
} catch (err) {
console.error('Invalid JWT:', err.message);
return null;
}
}Frequently Asked Questions
Can SafeWebhook verify JWKS (JSON Web Key Set) endpoints?
Yes. You can paste your JWKS URI into our validation helper to fetch the corresponding public key and verify RS256 signatures.
