Webhook Troubleshooting Guide

Comprehensive guide for diagnosing and resolving webhook verification failures

Quick Diagnostic Checklist
Run through these checks first
No Signature Detected in Header
The stripe-signature header is missing or empty

Symptoms

  • Error: "No signature found in stripe-signature header"
  • Webhook events fail with 400 status code
  • Signature verification throws "No signatures found" error

Common Causes

1. Reverse Proxy Stripping Headers

Some reverse proxies (nginx, cloudflare) may strip the stripe-signature header. Ensure your proxy configuration forwards all headers.

# Nginx: Add to your server block proxy_pass_request_headers on; proxy_set_header Stripe-Signature $http_stripe_signature;

2. Request Not Coming from Stripe

Direct browser requests or non-Stripe sources won't have the signature header. Verify the request is actually from Stripe's servers.

3. Middleware Consuming the Request

Body-parsing middleware may consume the raw body before it reaches your webhook handler.

// Next.js: Disable body parsing for webhook route export const config = { api: { bodyParser: false, }, };

Verification Steps

  1. Check if the header exists in incoming requests by logging all headers
  2. Verify your hosting platform forwards custom headers
  3. Test with Stripe CLI which always includes the signature
// Debug: Log all incoming headers console.log('Headers:', Object.fromEntries(request.headers.entries()));
Webhook Secret Mismatch
Signature verification fails due to incorrect secret
Timestamp & Clock Synchronization Issues
Server time drift causing signature validation failures
Endpoint URL Misconfiguration
Webhook URL is incorrect or inaccessible
Local Testing with Stripe CLI
Validate webhook reception and signature verification locally
Network & Firewall Issues
Connectivity problems blocking webhook delivery
Security Best Practices
Ensure secure webhook communication
Emergency Recovery
Steps to recover from webhook failures

1. Check Stripe Dashboard for Failed Events

Go to Developers → Webhooks → Select your endpoint → View recent deliveries

Open Webhook Dashboard

2. Resend Failed Events

Click on any failed event and use "Resend" to retry delivery

3. Fetch Events via API

If webhooks are unreliable, you can poll for events directly

stripe events list --limit 100

4. Manual Event Retrieval

Retrieve specific events by ID for manual processing

stripe events retrieve evt_xxxxxxxxxxxxx
