Webhooks are event-based notifications that are received when a specific event related to the KYC verification occurs.
In rare cases, such as network retries, read timeouts, processing delays, or delivery failures, the same webhook might be sent more than once for the same event. To prevent unintended side effects, implement idempotency in your webhook handler to handle duplicate deliveries.
