Do I need webhook dead-letter handling for failed events?

Yes—if you care about reliability, you should have dead-letter handling for failed webhooks.

Why it matters

Webhook delivery can fail for reasons outside your control:

• your endpoint is temporarily down
• timeouts / network issues
• malformed payloads
• downstream dependency failures
• rate limiting or overload

Without a dead-letter path, failed events can just disappear after retries are exhausted.

What dead-letter handling gives you

• Visibility: see which events failed and why
• Recovery: replay events after fixing the issue
• Data safety: avoid silent data loss
• Operations: separate transient failures from permanent ones

Typical pattern

1. Try delivery
2. Retry with backoff for transient errors
3. After max retries, move the event to a dead-letter queue/table/log
4. Alert on dead-letter accumulation
5. Provide a way to reprocess or manually inspect

When you might skip it

You might not need formal dead-letter handling if:

• webhooks are non-critical
• you can tolerate missed events
• the sender will handle retries and you don’t need to store failures
• the integration is low volume and manually recoverable

But even then, at least keep failure logs and alerting.

Practical recommendation

For most production systems:
Yes — implement retries + dead-letter handling + monitoring.

If you want, I can also suggest a simple webhook failure design pattern for your stack.
