Summary

Reliable webhook handling is essential for KYC and identity-verification workflows because failed notifications can delay onboarding, create data inconsistencies, and introduce compliance risks. Recommended practices include retrying transient failures with exponential backoff and random jitter, limiting attempts to avoid resource exhaustion, and distinguishing retryable issues such as timeouts or 5xx responses from permanent 4xx errors. Events that continue to fail should be placed in a Dead Letter Queue for inspection, reprocessing, archiving, and prevention of data loss. Webhook consumers should also be idempotent so duplicate deliveries do not create repeated records or side effects, using event identifiers, transactional processing, and, where necessary, locking mechanisms. Didit states that its platform provides signed webhook delivery, automatic retries, status reporting, APIs, and tools intended to support reliable delivery of identity-verification results, while organizations can add their own DLQs and processing safeguards.
