Proxy tester

A web-based tester for verifying credentials, debugging usernames, and inspecting what helodata reports back. Found at Dashboard → Resources → Proxy tester (and a public version at helodata.com/tools/proxy-tester).

What it does

Paste credentials, hit Test, and see:

• Whether auth succeeded
• The exit IP, country, state, city, ASN, and ISP
• Latency breakdown (connect / TLS / TTFB / total)
• The full Proxy-Authorization header that was sent
• Parsed username segments — useful when debugging bad-username errors
• Raw response headers from the gateway

When to use it

• Before deploying — confirm a sub-user's credentials and limits work
• Debugging 407 — see exactly what authorization header is being sent
• Verifying geo — does the exit IP match your region / state / city?
• Measuring latency — get a baseline for the gateway from your location
• Validating ASN targeting — confirm the carrier you wanted

Username parser

The tester accepts the full proxy URL or separate fields:

http://helo_s1a2b3c4d5e-type-res-region-us-state-ca-city-la:[e-mail]:7777

And displays:

prefix:    helo_
subuser:   s1a2b3c4d5e
type:      res         (residential)
region:    us
state:     ca
city:      la
session:   —           (none)
sesstime:  —
asn:       —

If a segment is malformed, the parser highlights it in red with a hint.

Geo verification

The tester reports:

• helodata-claimed geo (what X-Helodata-Exit-Geo says)
• MaxMind geo (a popular third-party DB used by many targets)
• IPinfo geo (a second third-party reference)

If these disagree, see IP location mismatch.

Programmatic test

For automated checks (CI smoke tests), use the API equivalent:

curl -X POST -H "Authorization: Bearer API_KEY" \
     -H "Content-Type: application/json" \
     -d '{
       "username": "helo_s1a2b3c4d5e-type-res-region-us",
       "password": "PASSWORD"
     }' \
     https://api.helodata.com/v1/tools/proxy-test

Response:

{
  "auth_ok":     true,
  "exit_ip":     "198.51.100.42",
  "exit_geo":    { "country": "us", "state": "ca", "city": "los angeles" },
  "exit_asn":    7922,
  "latency_ms":  { "connect": 24, "tls": 89, "ttfb": 178, "total": 312 },
  "parsed":      { "subuser": "s1a2b3c4d5e", "type": "res", "region": "us", "state": null, "city": null, "session_id": null, "sesstime": null, "asn": null }
}

Privacy

The tester never logs the password (it's masked from our internal logs even for support). The full request is held for 24 hours so you can compare results across runs, then deleted.

Common pitfalls

• Pasted with trailing whitespace — the tester catches this and warns, but many other clients silently fail. Trim.
• Tested on a different account's credentials — easy to do if you have multiple. The tester runs against the account whose API key it was issued for.
