N8n webhook replay backfill

N8n webhook replay backfill is an n8n automation template that re-plays incoming webhook requests and recovers missed events when the main workflow was down or failed during delivery. Reach for it when a webhook fired during an outage and the payload was lost, when you need to catch up a backlog of queued events without manually re-triggering each one, or when data integrity across integrations is non-negotiable and silent drops are unacceptable. Trigger: webhook. Integrations: none listed — relies on n8n-native buffering and replay logic nodes. The workflow is deployed by importing its JSON into a self-hosted or cloud n8n instance. The direction is replay and backfill of missed webhook events, not real-time routing of live incoming requests — for that, use standard webhook workflows in the catalogue. Works well for teams with unstable third-party integrations where every event must be accounted for; not suitable if the upstream webhook source has no ability to resend historical events from its own side.
