How do you handle webhook delivery failures?

Implement retry mechanisms with exponential backoff, dead letter queues for persistent failures, and proper alerting for manual intervention when needed.

What security measures are essential for webhook systems?

Use HMAC signatures for payload verification, validate SSL certificates, implement secret tokens, and consider IP whitelisting for critical endpoints.

How do you scale webhook systems during traffic spikes?

Use message queues to buffer requests, implement auto-scaling worker pools, and consider rate limiting with proper HTTP 429 responses to prevent overwhelming receivers.
