Redis Rate Limiting for Low-Code n8n APIs

This n8n workflow demonstrates robust rate limiting for low-code APIs using Redis. It starts with a Webhook node that captures incoming requests authenticated via header, extracting the API key from the payload. The key serves as a unique Redis identifier for the user. A Redis node increments the request counter and sets a 1-hour TTL for automatic expiration, ensuring counters reset periodically. Subsequent nodes, including another Redis increment and conditional logic (via IF nodes), evaluate
