Frequently Asked Questions

How do I set a proxy in Apify SDK?

In Apify SDK, you set the proxy endpoint (host:port), choose HTTP/HTTPS or SOCKS5, and add username/password credentials or allowlist your server IP. Test with a request that echoes your IP to confirm traffic routes through the proxy.

Why do I get proxy errors in Apify SDK?

Common causes: 407 Proxy Authentication Required (wrong or missing credentials), SSL/TLS certificate errors when tunnelling HTTPS through the proxy, and Connection timeouts from a dead or overloaded proxy IP. Verify auth, protocol, and that the proxy is live.

Should I use HTTP or SOCKS5?

HTTP/HTTPS covers almost all scraping. Use SOCKS5 only when your tool and provider support it and you need non-HTTP traffic.

How do I confirm the proxy is being used?

Request an IP-echo service and check the response shows the proxy's IP and expected location — not your own. Do this before building anything on top.

Why am I getting authentication errors?

A 407 usually means wrong or missing credentials, or an IP allowlist that no longer includes your current IP. Re-check the username/password and the allowlist.

How much bandwidth will Rotating Proxies in Apify SDK use?

It depends on page weight, retries, and how much media you load. Measure GB per successful result on a small run, then multiply by your target volume to estimate cost.

What is the best first provider to evaluate for Rotating Proxies in Apify SDK?

Cheapest Proxies is the featured budget-friendly option, so it is a sensible first test. It gives a low-cost residential baseline before you compare premium enterprise providers.
