N8n dead letter queue

N8n dead letter queue is an n8n automation template that implements a dead letter queue pattern for reliable error handling in webhook-driven pipelines. Reach for it when events are silently lost during downstream service outages, when you need automatic retry logic for failed requests without manual intervention, or when no incoming webhook event can be dropped even under transient failures. Trigger: webhook. Integrations: not specified in metadata. The template catches and buffers problematic messages so they can be reprocessed once the downstream step recovers — this is about fault tolerance and message retention, not primary routing or data transformation. Suitable for teams that want resilient n8n automations without building custom error-handling code; not a replacement for infrastructure-level message brokers like RabbitMQ or Kafka when hard delivery guarantees are required.
