N8n circuit breaker api

N8n circuit breaker api is an n8n automation template that implements the circuit breaker pattern to protect pipelines from cascading failures when calling external APIs. Trigger: webhook. Integrations: none declared. Reach for it when a third-party service goes down intermittently and you need the workflow to stop hammering a dead endpoint automatically, or when one flaky API keeps breaking an entire automation chain and you want self-healing recovery without manual restarts. The template contains state-switching logic (closed → open → half-open), an error counter, and a cooldown delay before retrying. Deploy by importing the JSON template into any n8n instance, self-hosted or cloud. The direction is outbound API call protection, not inbound traffic monitoring or rate-limiting of webhook consumers. Works well for teams shipping production integrations with unstable external services; not a substitute for infrastructure-level circuit breakers like Istio or Resilience4j when you need distributed fault tolerance across multiple services.
