Webhook 502 handling and dead letter queue

Our DFO endpoint is throwing 502 Bad Gateway when CXone retries the delivery. The standard retry logic just keeps hammering the failing URL. Need a way to route these failures to a dead letter queue for manual replay instead of infinite loops.

Is there a config flag in the webhook definition to enable DLQ routing, or do I need to handle this entirely on the consumer side?
