n8n

n8n is a workflow automation tool whose HTTP Request node accepts a proxy per request. Useful for low-code pipelines that scrape, monitor, or post to web services through helodata.

HTTP Request node

1. Drop an HTTP Request node.
2. Settings → Proxy (under the gear icon).
3. Fill in:

Residential / Mobile (gateway)

Field	Value
Proxy URL	http://helo_s1a2b3c4d5e-type-res-region-us:[e-mail]:7777

ISP

Field	Value
Proxy URL	http://helo_s1a2b3c4d5e:PASSWORD@198.51.100.42:8000

1. Save → Execute Node to test.

Workflow-wide proxy via env vars

For the n8n process itself (so every HTTP node inherits), set environment variables before launch:

export HTTP_PROXY="http://helo_s1a2b3c4d5e-type-res-region-us:[e-mail]:7777"
export HTTPS_PROXY="$HTTP_PROXY"
n8n start

n8n's underlying axios/HTTP layer honors these.

Rotating IPs across runs

Use n8n's Function node to generate a fresh session per execution:

const sid = Math.random().toString(36).slice(2, 10);
const user = `helo_s1a2b3c4d5e-type-res-region-us-session-${sid}-sesstime-10`;
return [{
  json: {
    proxy_url: `http://${user}:[e-mail]:7777`,
  },
}];

Pass {{ $json.proxy_url }} into the HTTP Request node's Proxy field.

ISP IP pool

Store your ISP list in a Set node (or fetch from a sheet/DB), pick a row via a Function node, and feed it into HTTP Request:

const ips = $input.first().json.lines;       // array of "ip:port:user:pass"
const line = ips[Math.floor(Math.random() * ips.length)];
const [ip, port, user, pass] = line.split(":");
return [{ json: { proxy_url: `http://${user}:${pass}@${ip}:${port}` } }];

Verify

Point the HTTP Request at https://ipv4.icanhazip.com and inspect the response.

Common pitfalls

• Self-hosted n8n behind a corporate proxy — n8n's HTTP node doesn't chain proxies. Only the last-set proxy wins.
• Special characters in password — URL-encode (@ → %40).
• Webhook trigger nodes don't go through proxies — they receive inbound traffic. Only outbound HTTP Request nodes do.
