Redis Rate Limiting for Low-Code n8n APIs

Implement API rate limiting using Redis in n8n: track requests by API key, increment counters with TTL, and block excess usage before processing data like Airtable queries.

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

How to import this workflow into n8n

  1. 1Purchase or download the workflow to get the n8n workflow JSON file.
  2. 2In your n8n instance, open Workflows and choose "Import from File" (or paste the JSON with Ctrl+V on the canvas).
  3. 3Open each node marked with a credential warning and connect your own accounts and API keys.
  4. 4Run the workflow once manually to verify the data flow, then toggle it to Active.
