Best practices for managing webhook event streams

LiveKit webhooks provide a mechanism for backend systems to receive near-realtime notifications about changes in rooms, participants, tracks, and lifecycle events, which can be used for application logic, auditing, billing, or initiating downstream jobs. The guide emphasizes building a reliable webhook consumer that can handle transient failures, suggesting that requests be acknowledged quickly while processing is deferred to a separate, asynchronous worker. Webhooks are delivered as push-based HTTP requests with JSON-encoded WebhookEvents and include a signed JWT for authenticity verification. Since delivery isn't guaranteed and retries can occur, consumers should be idempotent, storing raw payloads and using unique event IDs for deduplication. The document also advises against performing complex operations synchronously within the request path to prevent increased retries and potential duplicate processing. Monitoring for request rates, delivery success, and processing lags is crucial, and a suggested architecture includes capturing raw bodies, verifying signatures, enqueuing payloads, and using a worker to handle validation, state updates, and triggering further actions.
