[GUIDE] Actually Setting Up Your Proxies After You Buy Them
Bought a plan, applied the code (CBFHWA_724137 if you haven't yet — promo field at checkout, verify the total drops), and now you're staring at a list of IPs and ports wondering what to do with them. This is that guide.
What you get after purchase
Typically: a list of proxy addresses with ports, plus authentication details, plus documentation on which protocols are supported. Before touching anything, confirm which protocol your tool actually needs, because that determines a lot downstream.
Authentication: pick the right one for your setup
Two options, and picking wrong causes confusing failures.
IP whitelisting — you register your own connecting IP with the provider, and it just works without credentials. Clean and simple if your IP is static. If you're on a typical home or office connection where the IP changes periodically, this will silently break on you and you'll spend an afternoon wondering why authentication suddenly fails.
Username/password — works from any connecting IP. More flexible, and the safer default for most people. Just store the credentials properly (environment variables, secrets manager — not hardcoded in a script you might share or commit).
If you're unsure, use credentials.
Protocol: HTTP/HTTPS vs SOCKS5
- HTTP/HTTPS — fine for standard web requests, which covers most scraping and monitoring work
- SOCKS5 — handles a broader range of traffic types, more flexible, but not every tool supports it
Check what your actual tooling supports before you assume. This is easier to verify upfront than to debug later.
Browser setup
If you're working through a browser rather than scripts:
System-wide proxy settings work but route everything through one address, which is rarely what you want if you've got a pool.
A proxy management extension is usually the better move — lets you switch between configured proxies, apply different ones to different profiles, and store credentials so you're not re-entering them constantly.
Anti-detect / multi-profile browsers are what you want if you specifically need multiple isolated identities that don't share cookies, storage, or fingerprint characteristics. A standard browser wasn't built to keep separate identities separate, no matter how you configure the proxy layer. Relevant mainly for multi-account work.
Script setup
For automated work, proxies get configured directly in whatever HTTP library or framework you're using. Most modern libraries accept a proxy address and credentials as part of the request config, so you can route specific requests without touching system settings.
Two things people get wrong here:
Retry logic written for a single IP. If your existing code assumes one consistent address, introducing rotation can break assumptions in subtle ways. A retry that lands on a different IP than the original attempt behaves differently than a retry from the same IP. Worth reviewing your error handling when you first add a proxy layer.
Rotation logic in the wrong place. Some providers offer a single rotating endpoint that handles distribution server-side, which is simpler than managing a list of addresses and rotation logic yourself. Check whether that's available before writing your own.
Rotation settings — get this right
This trips people up more than anything else in setup.
Sticky session — holds the same IP for a set window. Use this for anything with continuity: logins, multi-step forms, carts, authenticated sessions. If your session window is shorter than your task takes to complete, the IP rotates mid-task and things break in weird, hard-to-diagnose ways.
Per-request rotation — new IP every request. Use for broad, stateless collection where each request stands alone.
Getting this backwards produces intermittent failures that look like random flakiness rather than a config issue, which is why it eats so much debugging time.
Test before you build on it
Before wiring proxies into a larger workflow, do a quick sanity check: connect through the proxy to something that reports back the IP it sees, and confirm it matches your pool rather than your own address. This catches the case where your config is silently falling back to a direct connection — which absolutely happens and is very easy to miss.
Then test against your actual targets, not just an IP checker. Connecting successfully in general doesn't mean a specific site will accept it.
Common setup failures, quick list
- Wrong protocol for the tool
- Whitelisting configured but connecting from a different IP
- Credentials updated in one place but not others
- Session window shorter than task duration
- Config silently falling back to direct connection
Work through those systematically and you'll resolve most issues without needing support.
Note
None of this changes based on whether you used a discount code. The setup is identical either way — the code just affected what you paid.
