Manage adaptive API rate limiting with a webhook proxy and Redis
Ready for 3.0Ready for 3.0. This template uses no nodes that n8n 3.0 removes. No removed nodes, versions or helpers found. Static check, last run 2026-10-19.
What this workflow does
This workflow has 26 nodes and runs when an HTTP POST request hits its webhook URL. Along the way it connects Redis.
How it runs
Trigger: When an HTTP POST request hits its webhook URL.
- Set - Limiter Config (Edit Fields (Set)): sets 12 fields: serviceName, requestPath, requestMethod…
- JS - Resolve Service (Code): runs custom JavaScript code
- If: checks a condition and branches into true / false
- Redis: get
- Respond - Unknown Service (404) (Respond to Webhook): sends the response back to the webhook caller
- JS - Compute Effective Limit (Code): runs custom JavaScript code
- If: checks a condition and branches into true / false
- Respond - Throttled (429) (Respond to Webhook): sends the response back to the webhook caller
- Redis: incr
- JS - Evaluate Quota (Code): runs custom JavaScript code
…plus 15 more steps. See the full node list below.
Services it uses
