If you’re using Stripe to handle payments, webhooks are critical. They notify your system in real time when events happen—like successful payments, failed charges, or subscriptions.
So when a Stripe webhook error occurs, your system can break silently. Orders may not update, users may not get access, and automation fails.
Let’s fix that.
What Is a Stripe Webhook Error?
A webhook error happens when Stripe sends an event to your server, but your endpoint:
- Fails to respond correctly
- Takes too long to respond
- Returns an error status code
Result: Stripe retries delivery, and your workflow becomes unreliable.
Common Causes of Stripe Webhook Errors
1. Server Returning Non-200 Status Code
Stripe expects a 200 OK response.
If your server returns:
- 400 (Bad Request)
- 500 (Server Error)
Stripe marks the webhook as failed.
2. Signature Verification Failure
Stripe signs each webhook request for security.
If your code fails to verify the signature:
- The request is rejected
- Event processing stops
3. Slow Response Time
If your server takes too long (usually over a few seconds):
- Stripe times out
- Retries begin
4. Incorrect Endpoint URL
- Wrong route
- Typos in webhook URL
- Endpoint not deployed
5. JSON Parsing Errors
- Invalid request body handling
- Middleware interfering with raw payload
6. Webhook Endpoint Down
- Server crash
- Hosting downtime
- DNS issues
How to Fix Stripe Webhook Errors
Step 1: Check Stripe Dashboard Logs
Go to:
Stripe Dashboard → Developers → Webhooks
- Click on failed events
- Review error messages
- Check response codes
Step 2: Ensure 200 OK Response
Your endpoint must return:
200 OK
Even if you process the event later.
Step 3: Verify Webhook Signature Properly
Use Stripe’s official libraries to validate:
- Signing secret must match
- Use raw request body (not parsed JSON)
Step 4: Handle Events Asynchronously
Don’t do heavy processing inside the webhook.
Instead:
- Receive event
- Queue it
- Process in background
Step 5: Fix Endpoint URL
- Double-check webhook URL in Stripe
- Ensure route is live and accessible
Step 6: Test Using Stripe CLI
Stripe provides tools to simulate events:
stripe listen --forward-to localhost:3000/webhook
This helps debug locally.
Best Practices for Reliable Webhooks
1. Always Acknowledge Fast
Return 200 OK immediately, then process later.
2. Implement Idempotency
Handle duplicate events safely.
Stripe may retry multiple times.
3. Log Everything
Store:
- Event ID
- Payload
- Processing status
4. Secure Your Endpoint
- Verify signatures
- Use HTTPS only
5. Monitor Failures
Set up alerts for repeated webhook failures.
How Long Does Stripe Retry?
Stripe retries failed webhook deliveries for up to:
- 3 days (live mode)
- With exponential backoff
What NOT to Do
- Don’t ignore failed webhook logs
- Don’t process events synchronously
- Don’t skip signature verification
- Don’t rely on a single webhook attempt
