Webhooks, essential for real-time data notifications, can be marked as unhealthy if issues arise. This guide from Unified.to provides a comprehensive approach to diagnosing and troubleshooting such webhooks, starting with checking the API call logs for errors. Common errors include bad requests (400), authentication failures (401), and permission issues (403), each requiring specific actions to resolve. Additionally, it discusses the importance of subscribing to a notifications webhook for immediate alerts on failures, and outlines various failure scenarios such as issues with subscription, token refresh, data reading, dispatching, and processing. The guide emphasizes verifying authentication credentials and scope settings, recreating connections if necessary, and ensuring correct server configurations. It also details a robust webhook retry mechanism using a Fibonacci backoff strategy to maximize delivery reliability over two weeks in cases of endpoint or API provider unavailability.
