Every guide belongs to one of the tasks below. Each task opens with the guide that answers it most completely, followed by the ones that go deeper.
Get one request routing through a proxy, then work out which proxy type the job actually needs.
Start with Send your first proxy request. The shortest path from a new account to a request that comes back through a Node4 IP.
Working proxy configuration for the HTTP clients and browser automation tools most projects already run.
Start with Proxy setup for Python requests, httpx and aiohttp. The three clients most Python scrapers are built on, with the exact proxy argument each one expects.
What an HTTP proxy and a SOCKS5 proxy each carry, and when switching changes the result you get.
Start with SOCKS5 proxy setup, and when it beats HTTP. SOCKS5 carries traffic an HTTP proxy cannot, and this guide covers both the setup and the cases where that shows up.
Prove a request is yours, then keep the credentials that unlock the account out of the wrong hands.
Start with Credentials, IP whitelisting and API keys compared. The three ways to authenticate, and which one suits a laptop, a fixed server or a CI runner.
Decide how often the exit IP changes, how long a session holds it, and where in the world it sits.
Start with Three ways to rotate proxy IPs. Per request, per session and on demand rotation side by side, with the request each one needs.
Create, rotate and audit proxies from your own code instead of clicking through the dashboard.
Start with Automate proxies with the management REST API. The dashboard actions that matter, available as authenticated HTTP calls your scripts can make.
Read the error you actually got, then work back to the cause in the order that is cheapest to rule out.
Start with Diagnose proxy connection failures. Refused connections, timeouts and TLS errors, separated by what each one proves about where the fault is.
Understand what you are billed for, and change a plan or add bandwidth without guessing at the result.
Start with Unmetered rotating access vs paying per gigabyte. How unmetered rotating access is measured, and when per gigabyte billing is the cheaper shape for the same work.
